Auswirkungen der Dürre 2018/19: Trockene Böden nach nassem Sommer
Authors: Kleine Lukas , Tetzlaff Dörthe , Smith Aaron
Published: March 2022

Die Sommermonate 2021 prägten Starkregen und mancherorts extreme Überflutungen – scheinbar ausreichend Niederschläge, um die Trockenheit der letzten Jahre auszugleichen. Untersuchungen des IGB in einem Teileinzugsgebiet der Spree (Brandenburg) zeigen, dass das vorhandene Wasserdefizit in dieser Region noch lange nicht ausgeglichen ist.
Brüssel rechnet mit Verknappung von Getreide
Authors: Mönch Axel
Published: March 2022

Weltweit dürften sich Warenströme durch den Krieg gegen die Ukraine verschieben. Seit russische Militärtruppen versuchen, die Ukraine zu übernehmen, ist der Getreidehandel aus dem Land ins Stocken geraten. Die Europäische Kommission versucht nun, die Produktion im EU-Binnenmarkt zu erhöhen. Für brachliegende Flächen könnten kurzfristig Ausnahmen gelten. Vor allem will die Brüsseler Behörde die Versorgung in nordafrikanischen Ländern, die Getreideerzeugnisse aus der Ukraine importieren, sichern. Der ukrainische Präsident Wolodymyr Selenskij bittet derweil um eine Aufnahme in die Europäische Union. Diese verweist allerdings auf ein langwieriges Beitrittsverfahren.

Kinetics of changes in the redox state of soils during their moistening and drying
Authors:   RGAU-MSHA named after K.A. Timiryazev, Tazin Ivan , Savich Vitaliy , Polyakov Alexei , Rashkovich Vasily
Published: March 2022

The development of excessive moisture in soils in early spring leads to the emergence of anaerobic conditions that limit the cultivation of agricultural crops. To predict the development of this process, an assessment of soil buffering in the redox interval, the buffer capacity of soils in the redox interval, and an assessment of the kinetics of the development of reducing conditions during soil anaerobiosis is proposed. According to the data obtained in chernozems, in comparison with sod-podzolic soils, the rate of fall of H during flooding is lower, the capacity of soils in the recovery interval is greater. The addition of KNO3 to the soil on the 14th day of flooding changes the Eh mv in sod-podzolic soil from -135 to +125 mv, in chernozem - from -105 to +170, pHO3 in sod-podzolic soil - from 4.0 to 2.0; in chernozem - from 3.0 to 2.0. It is proposed to apply these patterns when adjusting the components of farming systems on soils of excessive moisture in spring. Keywords: SOIL, REDOX STATE, ANAEROBIOSIS, AGROECOLOGICAL ASSESSMENT

The Environmental Stress Screening test objective is to validate proper manufacturing and find any manufacturing defects in a flight unit before delivery by using temperature modulation and vibration simulations. The ESS test performs temperature cycling and employs random vibrations to test the reliability of the unit. Temperature regulation is also provided via the poly-alpha-olefin (PAO) coolant flowing through the unit under test (UUT), which is controlled by a cooling system.
In-Situ Temperature Calibration Capability for Dimensional Metrology
Authors:   National Institute of Standards and Technology, Rachakonda P.
Published: March 2022

The Dimensional Metrology Group (DMG) at the National Institute of Standards and Technology (NIST) has the capability to perform large range dimensional measurements in a facility called the Tape Tunnel. The Tape Tunnel is equipped with a 60 m long steel bench and a reference interferometer. Various artifacts and instruments, such as tape measures, optical cables, laser trackers, laser distance meters etc. are calibrated against the reference interferometer. The relative uncertainty (Uk=2) in the displacement measurement is 2.4×10-7. A major component of this uncertainty is the uncertainty in measuring the temperature in the Tape Tunnel. There are 14 temperature probes installed along the length of the steel bench; two each at seven equidistant locations. One probe measures the air temperature and the other measures the material temperature (of the steel bench). Historically, calibrating these probes involved removing all the 14 probes and sending them to the NIST Thermodynamic Metrology Group. This process introduced a considerable amount of downtime to the DMG’s measurement capabilities. This also introduced uncertainties due to a) variation in the contact geometry of the material probe with the steel bench during reinstallation, and b) variation in the resistances of the probes’ cables due to pinching and/or elongation. In an attempt to address these issues, a new in-situ temperature calibration system was developed. This paper discusses the system components, an in-situ calibration procedure, the uncertainty sources involved in the calibration process, presents an uncertainty budget, and examines it with a Monte Carlo simulation. This system enables the DMG to perform quicker in-situ temperature calibration, at frequent intervals, with minimal downtime and provides better uncertainties in the dimensional measurements.
Issues in the testing of Portable Coordinate Measuring Systems (CMS)
Authors:   Center for Precision Metrology, Morse Edward
Published: March 2022

Historically, coordinate measuring machines (CMMs) are delivered to a room provided by the customer, with environmental controls (primarily temperature) that meet the CMM manufacturer's requirements. More sophisticated compensation methods and the use of advanced materials have led to the ability to place CMMs on the factory floor, but there are still environmental limits which must be satisfied in order for the CMM to perform as specified. Performance testing of CMMs follows (in general) the rubric that the error observed in a length measurement of a reference artifact must not exceed the CMM specification, provided the required environmental conditions are met. If we consider portable coordinate measuring systems (CMSs), such as articulating arm CMMs and laser trackers, the same general guidelines pertain to performance testing. There are, however, two differences in these instruments that introduce ambiguity with respect to the testing and calibration of these instruments. The first difference is that these instruments use an operator to perform measurements, where a CMM is computer controlled and largely independent of the operator. It is possible that an inexperienced operator may have difficulty in successfully completing a performance test of the instrument. If a technician representing the instrument manufacturer can successfully complete the test, is this adequate? Or must it be possible for any properly trained operator to achieve a successful result? The second difference in portable CMS is that . due to their portability . they are often sent to an offsite laboratory for performance testing and calibration. These offsite laboratories often have very good temperature control, performing the tests at 20 .C ™} 2.C, while the instruments are specified to perform at (for example) .5 .C to +40 .C. How then is the user able to be confident that the instrument will perform as designed in their own environment? What avenues are available to determine that the instrument continues to remain in conformance to the manufacturer specifications?
Estimating Thermal Effects for Granite Surface Plate Calibration
Authors:   ASQ Fellow, CQE, CCT, Skattum Gordon A.
Published: March 2022

SME B89.3.7-2013, Granite Surface Plates, is a revision of the 1973 Federal Specification GGG-P-463c which has been used exclusively in American industry since its publication as the standard for calibration practices. Accredited and non-accredited calibration services cite compliance to the Federal Specification and are now becoming aware of the new ASME replacement. The calibration and acceptance of overall flatness for new certification, recertification in the field, and recertification after resurfacing is highly influenced by temperature variation and spatial thermal gradients. However, a complete understanding and application of thermal effects by users and calibration services has been hit-or-miss. The 2013 standard, in Nonmandatory Appendix F Guidance to Estimating Uncertainty in Surface Plate Measurement, identifies the importance of temperature but provides limited guidance for estimating uncertainty in flatness due to thermal effects. This paper will explore the sources of variation and thermal effects applied to granite surface plate calibration and impact on the quality, uncertainty, and appropriate decisions when to resurface. It will also address ASME B89.3.7-2013, Appendix F, section F-4.1 Temperature, and provide an approach for estimating uncertainty components due to these temperature related sources. The components, especially temperature stability, are always present and can significantly affect or dominate uncertainty in calibration of overall flatness. Examples will demonstrate that thermal effects should be included in any uncertainty budget for calibration of overall flatness as required by ANSI/ISO/IEC 17025:2005(E). [2] Finally, the session will demonstrate an Excel application to assist evaluation of thermal effects on granite surface plate calibration. An important and ongoing effort related to this paper seeks to research, identify and document current industry practices so as to provide guidelines for “best practice” calibration of granite surface plates.
Removing the Skills Gap in Manufacturing
Authors:   Purdue University, Pippenger Brian
Published: March 2022

This paper will look into the growing problem of the skills gap in manufacturing. The speed at which technology is changing in the work place is phenomenal. Many of the manual functions of the past are run from computers. Computers run many of the machining functions; computer controllers are keeping track of every move the tools make, robots move parts from one operation to the next and conveyor systems controlled by computers that move the parts in automated cells. Processes that originally required ten or more employees now only need two or three. The dilemma is that these two or three employees need to be highly skilled in many areas of the process not just the operation of one machine in the process. This is where in the problem lies. How do companies address this skills gap in order to bring their employees to a skill level that will afford a level of confidence in operating of the automated processes that are now being implemented into our manufacturing systems? Many of the newest technologies are obsolete before they hit the floor. Organizations will need to evaluate their need for upgrading their technology to keep up with the competition. Will the implementation of new technology be essential in the future of the manufacturing process and staying ahead of the competition? What will the learning curve be for the new technology? Can training in advance of the implementation be feasible? Are the employees adding to their existing skill set or will this new technology require a new skill for them to learn? Providing an opportunity for training is only part of the answer. Many of the employees have not had structured education for many years or do not have the skill set needed for the new technologies that are being released. Removing the fear in the workplace so that everyone may work effectively for the company, institute a vigorous program of education and self-improvement, and allow the employee the freedom to have pride in their work will make the transition as painless as possible for the employee and the organization.

Highly supercooled riming and unusual triple-frequency radar signatures over Antarctica
Authors: Tridon Frédéric , Silber Israel , Battaglia Alessandro , Kneifel Stefan , Fridlind Ann , Kalogeras Petros , Dhillon Ranvir
Published: March 2022

Abstract. Riming of ice crystals by supercooled water droplets is an efficient ice growth process, but its basic properties are still poorly known. While it has been shown to contribute significantly to surface precipitation at mid-latitudes, little is known about its occurrence at high latitudes. In Antarctica, two competing effects can influence the occurrence of riming: the scarcity of supercooled liquid water clouds due to the extremely low tropospheric temperatures and the low aerosol concentration, which may lead to the formation of fewer and larger supercooled drops potentially resulting in an enhanced riming efficiency. In this work, by exploiting the deployment of an unprecedented number of multi-wavelength active and passive remote sensing systems (including triple-frequency radar measurements) in West Antarctica, during the Atmospheric Radiation Measurements West Antarctic Radiation Experiment (AWARE) field campaign, we evaluate the importance of riming incidence in Antarctica and find that riming occurs at much lower temperatures compared to the mid-latitudes. We then focus on a case study featuring a persistent layer of unexpectedly pronounced triple-frequency radar signatures but only a relatively modest amount of supercooled liquid water. In-depth analysis of the radar observations suggests that such signatures can only be explained by the combined effects of moderately rimed aggregates or similarly shaped florid polycrystals and a narrow particle size distribution (PSD). Simulations of this case study performed with a 1D bin model %by introducing an additional class corresponding to rimed ice indicate that similar triple frequency radar observations can be reproduced when narrow PSDs are simulated. Such narrow PSDs can in turn be explained by two key factors: (i) the presence of a shallow homogeneous droplet or humidified aerosol freezing layer aloft seeding an underlying supercooled liquid layer, and (ii) the absence of turbulent mixing throughout a stable polar atmosphere that sustains narrow PSDs, as hydrometeors grow from the nucleation region aloft to several millimeter ice particles, by vapor deposition and then riming.
Theoretical and numerical considerations of rivers in a tectonically inactive foreland
Authors: Hergarten Stefan
Published: March 2022

Abstract. Recent advances in the numerics of fluvial landform evolution models allow for large-scale simulations of erosion and sediment transportover time spans of several million years. This study aims at finding out fundamental properties of rivers in a tectonically inactive foreland of a mountain range by investigating a simple reference scenario. This scenario consists of a mountain range and a foreland in a quasi-steady state where the material eroded in the mountain range is routed through the foreland. In order to understand the properties of foreland rivers, a subdivision into two classes – carriers and redistributors – is introduced. Carriers originate in the mountain range and are thus responsible for the large-scale sediment transport to the ocean. In turn,redistributors are rivers whose entire catchment is located in the foreland. Using the concept of carriers and redistributors, it is shown that the drainage network in the foreland permanently reorganizes, so that a steady state in the strict sense is impossible. However, the longitudinal profiles of carriers are described well by a steady-state approximation. Their concavity index is considerably greater than that of rivers in the mountain range. Carriers are predominantly depositing sediment at high rates, while redistributors are eroding at much lower rates. Despite the low erosion rates, the sediment flux from redistributors into carriers is a major component of the overall sediment budget and finally the main driver of the highly dynamic behavior of the carriers.
A new snow module improves predictions of the isotope-enabled MAIDENiso forest growth model
Authors: Hermoso de Mendoza Ignacio , Boucher Etienne , Gennaretti Fabio , Lavergne Aliénor , Field Robert , Andreu-Hayles Laia
Published: March 2022

Abstract. The representation of snow processes in forest growth models is necessary to accurately predict the hydrological cycle in boreal ecosystems and the isotopic signature of soil water extracted by trees, photosynthates and tree-ring cellulose. Yet, most process-based models do not include a snow module; consequently, their simulations may be biased in cold environments. Here, we modified the MAIDENiso model to incorporate a new snow module that simulates snow accumulation, melting and sublimation, as well as thermal exchanges driving freezing and thawing of the snow and the soil. We tested these implementations in two sites in eastern and western Canada for black spruce (Picea mariana (Mill.) B.S.P.) and white spruce (Picea glauca (Moench) Voss) forests, respectively. The new snow module improves the skills of the model to predict components of the hydrological cycle. The MAIDENiso model is now able to reproduce the spring discharge peak and to simulate stable oxygen isotopes in tree-ring cellulose more realistically than in the original snow-free version of the model. The new implementation also results in simulations with a higher contribution from the source water on the oxygen isotopic composition of the simulated cellulose, leading to more accurate estimates of cellulose isotopic composition. Future work may include the development of inverse modelling with this new version of MAIDENiso to produce robust reconstructions of the hydrological cycle and isotope processes in cold environments.
Geometric remapping of particle distributions in the Discrete Element Model for Sea Ice (DEMSI v0.0)
Authors: Turner Adrian K. , Peterson Kara J. , Bolintineanu Dan
Published: March 2022

Abstract. A new sea ice dynamical core, the Discrete Element Model for Sea Ice (DEMSI), is under development for use in coupled Earth system models. DEMSI is
based on the discrete element method, which models collections of ice floes as interacting Lagrangian particles. In basin-scale sea ice simulations
the Lagrangian motion results in significant convergence and ridging, which requires periodic remapping of sea ice variables from a deformed
particle configuration back to an undeformed initial distribution. At the resolution required for Earth system models we cannot resolve individual
sea ice floes, so we adopt the sub-grid-scale thickness distribution used in continuum sea ice models. This choice leads to a series of hierarchical
tracers depending on ice fractional area or concentration that must be remapped consistently. The circular discrete elements employed in DEMSI help
improve the computational efficiency at the cost of increased complexity in the effective element area definitions for sea ice cover that are
required for the accurate enforcement of conservation. An additional challenge is the accurate remapping of element values along the ice edge, the
location of which varies due to the Lagrangian motion of the particles. In this paper we describe a particle-to-particle remapping approach based on
well-established geometric remapping ideas that enforces conservation, bounds preservation, and compatibility between associated tracer quantities,
while also robustly managing remapping at the ice edge. One element of the remapping algorithm is a novel optimization-based flux correction that
enforces concentration bounds in the case of nonuniform motion. We demonstrate the accuracy and utility of the algorithm in a series of numerical
test cases.

Abstract. Future hydrological behavior in a changing world is typically predicted based on models that are calibrated on past observations, disregarding that hydrological systems and, therefore, model parameters may change as well. In reality, hydrological systems experience almost continuous change over a wide spectrum of temporal and spatial scales. In particular, there is growing evidence that vegetation adapts to changing climatic conditions by adjusting its root zone storage capacity, which is the key parameter of any terrestrial hydrological system. In addition, other species may become dominant, both under natural and anthropogenic influence. In this study, we test the sensitivity of hydrological model predictions to changes in vegetation parameters that reflect ecosystem adaptation to climate and potential land use changes. We propose a top-down approach, which directly uses projected climate data to estimate how vegetation adapts its root zone storage capacity at the catchment scale in response to changes in the magnitude and seasonality of hydro-climatic variables. Additionally, long-term water balance characteristics of different dominant ecosystems are used to predict the hydrological behavior of potential future land use change in a space-for-time exchange. We hypothesize that changes in the predicted hydrological response as a result of 2 K global warming are more pronounced when explicitly considering changes in the subsurface system properties induced by vegetation adaptation to changing environmental conditions. We test our hypothesis in the Meuse basin in four scenarios designed to predict the hydrological response to 2 K global warming in comparison to current-day conditions, using a process-based hydrological model with (a) a stationary system, i.e., no assumed changes in the root zone storage capacity of vegetation and historical land use, (b) an adapted root zone storage capacity in response to a changing climate but with historical land use and (c, d) an adapted root zone storage capacity considering two hypothetical changes in land use. We found that the larger root zone storage capacities (+34 %) in response to a more pronounced climatic seasonality with warmer summers under 2 K global warming result in strong seasonal changes in the hydrological response. More specifically, streamflow and groundwater storage are up to −15 % and −10 % lower in autumn, respectively, due to an up to +14 % higher summer evaporation in the non-stationary scenarios compared to the stationary benchmark scenario. By integrating a time-dynamic representation of changing vegetation properties in hydrological models, we make a potential step towards more reliable hydrological predictions under change.
Structure of digital metrological twins as software for uncertainty estimation
Authors: Poroskun Ivan , Rothleitner Christian , Heißelmann Daniel
Published: March 2022

Abstract. Ongoing digitalization in metrology and the ever-growing complexity of measurement systems have increased the effort required to create complex software for uncertainty estimation. To address this issue, a general structure for uncertainty estimation software will be presented in this work. The structure was derived from the Virtual Coordinate Measuring Machine (VCMM), which is a well-established tool for uncertainty estimation in the field of coordinate metrology. To make it easy to apply the software structure to specific projects, a supporting software library was created. The library is written in a portable and extensible way using the C++ programming language. The software structure and library proposed can be used in different domains of metrology. The library provides all the components necessary for uncertainty estimation (i.e., random number generators and GUM S1-compliant routines). Only the project-specific parts of the software must be developed by potential users. To verify the usability of the software structure and the library, a Virtual Planck-Balance, which is the digital metrological twin of a Kibble balance, is currently being developed.
Characterizing the Rate of Spread of Wildfires in Emerging Fire Environments of Northwestern Europe
Authors: Tapia Victor Mario , Monedero Santiago , Little Kerryn , de-Miguel Sergio , Stoof Cathelijne , Cardíl Adrián
Published: March 2022

Abstract. In recent years fires of greater magnitude have been documented throughout northwest Europe, and with several climate projections indicating future increases in fire activity in this temperate area, it is imperative to identify the status of fire in this region. This study unravels important unknowns about the state of the fire regime in northwest Europe by characterizing one of the key aspects of fire behavior, the rate of spread (ROS). Using an innovative approach to cluster VIIRS hotspots into fire perimeter isochrones to derive ROS, we identify the effects of land cover and season on fire rate of spread of 254 landscape fires that occurred between 2012 and 2020. Results reveal no significant differences between land cover types and there is a clear peak of ROS and burned area in the months of April and May. During this late spring period, 67 % of the burned area occurs and median fire runs are approximately 0.16 km/hr during a 12 hour overpass. Heightened ROS and burned area values persist in the bordering months of March and June suggesting that may present the extent of the fire season in northwestern Europe. Accurate data on ROS among the represented land cover types as well as periods of peak activity are essential for determining periods of elevated fire risk, the effectiveness of available suppression techniques as well as appropriate mitigation strategies (land and fuel management).
Challenges assessing the effect of AMVs to improve the predictability of a medicane weather event using the EnKF. Storm-scale analysis and short-range forecast
Authors: Carrió Diego Saúl
Published: March 2022

Abstract. Coastal population in the Western Mediterranean basin is frequently affected by high-impact weather events that produce loss of life and property for an invaluable amount. Among the wide spectrum of maritime severe weather events, tropical-like Mediterranean cyclones (a.k.a. medicanes) draw particular attention, specially due to their poor predictability. The accurate prediction of this kind of events still remains a key challenge to our community, mainly because of (i) the errors in the initial conditions, (ii) the lack of accuracy modeling micro-scale physic processes and (iii) the chaotic behavior inherent to current numerical weather prediction models. In particular, the 7th October 2014 Qendresa medicane, that took place over the Sicilian channel, affecting the Islands of Lampedusa, Pantelleria and Malta was selected for this study because of its extremely low predictability behavior in terms of its track and intensity. To enhance the prediction of Qendresa, a high-resolution (4-km) ensemble-based data assimilation technique, known as Ensemble Kalman Filter (EnKF) is used. In this study both in-situ conventional and satellite-derived observations are assimilated with the main objective of improving Qendresa's model initial conditions and thus, its subsequent forecast. The performance of the EnKF system and its impact on the Qendresa forecast is quantitatively assessed using different deterministic and probabilistic verification methods. A discussion in terms of the relevant physical mechanisms adjusted by the EnKF is also provided. Results reveal that the assimilation of both conventional and satellite-derived observations improves the short-range forecasts of the trajectory and intensity of Qendresa. In this context, it is shown the relevance of assimilating satellite-derived observations to improve the pre-convective estimation of Qendresa's upper-level dynamics, which is key to obtain a realistic track and intensity forecast of this event.
Interactions between precipitation, evapotranspiration and soil moisture-based indices to characterize drought with high-resolution remote sensing and land-surface model data

Published: March 2022

Abstract. The Iberian Peninsula is prone to drought due to the high variability of the Mediterranean climate with severe consequences for drinking water supply, agriculture, hydropower, and ecosystems functioning. In view of the complexity and relevance of droughts in this region, it is necessary to increase our understanding of the temporal interactions of precipitation, evapotranspiration and soil moisture that originate drought within the Ebro basin, in northeast Spain, as study region. Remote sensing and land-surface models provide high spatial and temporal resolution data to characterize evapotranspiration and soil moisture anomalies in detail. The increasing availability of these datasets has potential to overcome the lack of in-situ observations of evapotranspiration and soil moisture. In this study, remote sensing data of evapotranspiration from MOD16A2ET and soil moisture data from SMOS1km as well as SURFEX-ISBA land-surface model data are used to calculate the EvapoTranspiration Deficit Index (ETDI) and the Soil Moisture Deficit Index (SMDI) for the period 2010–2017. The study compares the remote sensing time series of these ETDI and SMDI indices with the ones estimated using the land-surface model SURFEX-ISBA, including the Standardized Precipitation Index (SPI) computed at weekly scale. The study focuses on the analysis of the temporal lags between the indices to identify the synchronicity and memory of the anomalies between precipitation, evapotranspiration and soil moisture to interpret factors involved in drought onset. Lag analysis results demonstrate the capabilities of the SPI, ETDI and SMDI drought indices to inform about the mechanisms of drought propagation at distinct levels of the land-atmosphere system. Relevant feedbacks both for antecedent and subsequent conditions are identified, with a preeminent role of evapotranspiration in the link between rainfall and soil moisture. Both remote sensing and land-surface model show capable to characterize drought events, with specific advantages and drawbacks of the remote sensing and land-surface model datasets. Results underline the value of analyzing drought with dedicated indices, preferably at weekly scale, to better identify the quick self-intensifying and mitigating mechanisms governing drought, which are relevant for drought monitoring in semi-arid areas.

Abstract. First analyses of landslide distribution and triggering factors are presented for the region affected by the August, 14, 2021, Nippes, earthquake (Mw = 7.2) in Haiti. Landslide mapping was mainly carried out by comparing pre- and post-event remote imagery (~0.5–1-m resolution) available on Google Earth Pro® and Sentinel-2 (10-m resolution) satellite images. The first covered about 50 % of the affected region (for post-event imagery and before completion of the map in January 2022), the latter were selected to cover the entire potentially affected zone. On the basis of the completed landslide inventory, comparisons are made with catalogues compiled by others both for the August 2021 and the January 2010 seismic events, including one open inventory (by the United States Geological Survey) that was also used for further statistical analyses. Additionally, we studied the pre-2021 earthquake slope stability conditions. These comparisons show that the total number of landslides mapped for the 2021 earthquake (7091) is smaller than the one observed by two other research teams for the 2010 event (e.g., 23,567, for the open inventory). However, these fewer landslides triggered in 2021 cover much wider areas of slopes (> 80 km2) than those induced by the 2010 event (~25 km2 – considering the open inventory). A simple statistical analysis indicates that the lower number of 2021-landslides can be explained by the ‘under-mapping’ of smallest landslides triggered in 2021, partly due to the lower resolution imagery available for most of the areas affected by the recent earthquake; this is also confirmed by an inventory completeness analysis based on size-frequency statistics. The much larger total area of landslides triggered in 2021, compared to the 2010 earthquake, can be related to different physical reasons: a) the larger earthquake magnitude in 2021; b) the more central location of the fault segment that ruptured in 2021 with respect to coastal zones; c) and possible climatic preconditioning of slope stability in the 2021-affected area. These observations are supported by (1) a new pre-2021 earthquake landslide map, (2) rainfall distribution maps presented for different periods (including October 2016 – when Hurricane Matthew had crossed the western part of Haiti), covering both the 2010 and 2021 affected zones, as well as (3) shaking intensity prediction maps.

Published: March 2022

This article discusses the three Finnish city names Helsinki, Espoo, and Vantaa, and the urban discourses that surround them. The study reveals patterns of socio-spatial differentiation by examining what meanings people attach to these capital region cities and investigating how these meanings are expressed in online discourses. Using the methodological approach of corpus-assisted onomastics (CAO), this study incorporates onomastics, geographical information systems (GIS), and corpus linguistics. This interdisciplinary research also examines how corpus-assisted discourse studies (CADS) and GIS can be combined to reveal and visualize the contextual information and discursive patterns of toponyms. For this investigation, a data set of 2.7 billion words was collected from the Suomi24 Corpus, one of the biggest discussion fora in Finland. The use of social media corpus as a data source increases the authenticity of this research, as the data was not collected specifically for this study. The analysis reveals that the most frequent digital discourses about the cities refer to places and directions, housing, and mobility. The occurrences differ quantitatively and qualitatively between each city. This paper paves the way for future onomastic studies to research actual name usage using this new methodology. Knowledge gained from such research may not only enrich the field of onomastics, but also facilitate more socially sustainable urban planning.
