Published: March 2023

This study aimed to examine the relationship between psychological well-being and self-confidence in exercise participants and investigate the effect on it. Personal Information Form, Psychological Well-Being Scale, and Self-Confidence Scale were data collection tools. Participants were reached by convenience sampling method, one of the sampling methods not based on probability. The research population consisted of individuals aged 18-45 who regularly exercise (30 minutes at least three days a week for one year). The study sample consisted of 306 participants, 145 men (47.39%), and 161 women (52.61%), who exercise regularly. Pearson Correlation and Regression analysis were used through the SPSS package program to analyze the obtained data. When the research results were examined, it was seen that psychological well-being had a positive and significant effect on internal and external self-confidence (p<0.05). As a result, psychological well-being is an important predictor of internal self-confidence (62.0%) and external self-confidence (41.0%) in exercise participants.

Atmospheric composition and climate impacts of a future hydrogen economy

Published: March 2023

Abstract. Hydrogen is expected to play a key role in the global energy transition to net zero emissions in many scenarios. However, fugitive emissions of hydrogen into the atmosphere during its production, storage, distribution and use could reduce the climate benefit and also have implications for air quality. Here we explore the atmospheric composition and climate impacts of increases in atmospheric hydrogen abundance using the UKESM1 chemistry-climate model. We find that increases in hydrogen result in increases in methane, tropospheric ozone and stratospheric water vapour, resulting in a positive radiative forcing. However, some of the impacts of hydrogen leakage are partially offset by potential reductions in emissions of methane, carbon monoxide, nitrogen oxides and volatile organic compounds from the consumption of fossil fuels. We derive a new methodology for determining indirect Global Warming Potentials from steady-state simulations which is applicable to both shorter-lived species and those with intermediate and longer lifetimes, such as hydrogen. Using this methodology, we determine a 100-year Global Warming Potential for hydrogen of 12 ± 6. To maximise the benefit of hydrogen as an energy source, emissions associated with hydrogen leakage and emissions of the ozone precursor gases need to be minimised.
Airborne coherent wind lidar measurements of the momentum flux profile from orographically induced gravity waves

Published: March 2023

Abstract. In the course of the GW-LCYCLE II campaign, conducted in Jan/Feb 2016 from Kiruna, Sweden, coherent Doppler wind lidar (2 µm DWL) measurements were performed from the DLR Falcon aircraft to investigate gravity waves induced by flow across the Scandinavian Alps. During a mountain wave event on 28 January 2016, a novel momentum flux (MF) scan pattern with fore and aft propagating laser beams was applied to the 2 µm DWL. This allows us to measure the vertical wind and the horizontal wind along the flight track simultaneously with a high horizontal resolution of ≈800 m and hence enables us to derive the horizontal MF profile for a broad wavelength spectrum from a few hundred meters to several hundred kilometers. The functionality of this method and the corresponding retrieval algorithm is validated using a comparison against in situ wind data measured by the High Altitude and Long Range (HALO) aircraft which was also deployed in Kiruna for the POLSTRACC (Polar Stratosphere in a Changing Climate) campaign. Based on that, the systematic and random error of the wind speeds retrieved from the 2 µm DWL observations are determined. Further, the measurements performed on that day are used to reveal significant changes in the horizontal wavelengths of the vertical wind speed and of the leg-averaged momentum fluxes in the tropopause inversion layer (TIL) region, which are likely to be induced by interfacial waves as recently presented by Gisinger et al. (2020).

Published: March 2023

Abstract. Aerosol electrometers are widely applied to measure the number concentration and other physical parameters of particles. In this work, a new aerosol electrometer, i.e., Thermal Precipitation Aerosol Electrometer (TPAE), was designed and its performance was experimentally evaluated. The TPAE integrates a thermal precipitator with a micro- current measurement circuit board for measuring electrical charges carried by particles. The thermal precipitator was in the disk-to-disk configuration. Heating paster and air cooling were adopted to establish a temperature gradient in the precipitator. At a sample flow rate of 0.3 L/min and temperature gradient of 254 K/cm, the precipitation efficiency of particles reaches ~100 %. The measurement range of the designed aerosol electrometer was ±5×105 fA, with the accuracy of ±2 fA. In the evaluation, the electrical performance of TPAE was evaluated using DMA (differential mobility analyzer)-classified sodium chloride and soot particles and compared it to that of the reference faraday-cage aerosol electrometer. The precipitation performance of TPAE was then studied as the functions of temperature gradient, sampling flowrate and particle size. It is shown that the particle collection efficiency of built-in thermal precipitator is inversely proportional to the sampling flow rate, and proportional to the temperature gradient. The effect of particle size on the above efficiency was minor for sodium chloride particles. Different from that observed for NaCl particles, the slightly positive correlation of the collection efficiency with the electrical mobility size was observed for soot particles (in the size range of 30 ~ 160 nm). It might be due to soot agglomerates. The designed aerosol electrometer with the soft particle collection could be used in, e.g., field studies requiring to both measuring the particle charges and collecting particles for offline morphology, chemistry, and other studies.
Operational hail forecasting in Greece

Published: March 2023

Since 2021, the METEO unit of the National Observatory of Athens (NOA) in Greece implemented a multi-model operational hail forecasting system. In our forecasting system we make use of four high-resolution numerical weather prediction models, namely BOLAM, WRF-ARW, MOLOCH, and ICON. BOLAM, WRF-ARW and MOLOCH are operated by NOA and run twice per day at 00Z and 12Z, while ICON is operated by the German Weather Service (DWD) and runs eight times per day. For the purpose of our application here we use the 00Z and 12Z initialization times for all four models and we focus our analysis over the domain of Greece extending from 18˚ to 30˚E and from 34˚ to 43˚ N. Here we apply the newly developed Hail Size Index (HSI) as an offline diagnostic tool in the four models for forecasting the expected maximum hail size. We choose HSI against other commonly used indices (e.g. significant hail parameter) because by construction it is more suitable for estimating hail size in European thunderstorms. The computation of HSI takes into account the atmospheric instability, wind shear, freezing level height, lifting condensation level, equilibrium height and temperature lapse rate. Here we present preliminary results of a validation of our hail forecasting system using observations from the European Severe Weather Database (ESWD) provided by the European Severe Storms Laboratory (ESSL). Our analysis primarily focuses on the predictability of large hail (> 2.5 cm) events which can lead to significant economic losses. In addition, we also attempt to assess the predictability of high accumulation of small hail (< 2.5 cm) events which can still pose a threat to agriculture and travel safety.

Published: March 2023

The PERiLS (Propagation, Evolution and Rotation in Linear Storms) project is designed to study tornadoes produced by Quasi-Linear Convective Systems (QLCS) in the southeast United States.  QLCS-spawned tornadoes pose a significant threat to lives and property, but forecasting QLCS tornado events poses special challenges, more so than forecasting supercell tornadoes.  PERiLS is the largest and most ambitious field project focusing on QLCSs tornadoes, combining a dense, adaptable X- and C-band research radar array, including substantial instrumentation from the Flexible Array of Radars and Mesonets (FARM) including  the new quickly-assembled C-band On Wheels (COW), two Doppler On Wheels (DOW) a multitude of quickly-deployable surface instruments (PODNET), the UI deployable wind profiler, Mobile Mesonets, and several upper air sounding systems, to provide the sampling necessary to address environmental factors and storm processes that lead to QLCS tornadogenesis.  PERiLS is a multi-year field project; the first field phase occurred from 1 March to 1 May 2022; and the second field phase from 8 February to 8 May 2023.  

Preliminary data and analyses that address the science objectives of the National Science Foundation research teams, the pre-scouting and design of a radar network for each IOP, and other unique experimental field project design will be discussed.  During the 2022 field phase, PERiLS conducted four IOPs, during which tornado strength rotations were observed.  Preliminary analyses of IOPs 1 and 3 will be presented and an overview of the data collected during PERILS-2023 will be presented. 

 
Reconstruction of tornado environments in Romania (1981-2020) using the ERA5 reanalysis

Published: March 2023

The general interest in tornado studies has been stimulated by scientific challenges, such as a better understanding of their genesis and development, and by applications and practical issues, such as forecast, building engineering, and risk analysis. This context justifies the interest in reconstructing tornado characteristics based on different approaches. The recently released ERA5 reanalysis data set at 31 km-horizontal resolution, and hourly temporal resolution holds significant potential for many climate applications. In this paper, the tornado environments in Romania between 1981-2020 are reconstructed using a series of thermodynamic and kinematic parameters (e.g., 0-1 km bulk wind shear, 0-6 km bulk wind shear, 0-500m mixed-layer CAPE, ML WMAX*SHEAR) calculated based on ERA5 data. A previous paper on the climatology of tornadoes in Romania showed that in the 1980s there was a minimum in the tornado activity (1 tornado report) followed by a period with a large number of reports (138 reports, approximately 4 tornadoes per year). The aim of the paper is twofold. First, we want to investigate the changes in the occurrence of tornado environments in Romania and thus understand if the minimum in tornado reporting in 1980 is due to tornadoes being ignored by the researchers and meteorologists (and reported as swerve wind events) or natural variability. Second, to study the spatial and temporal variability of the tornadoes in Romania in relation to large-scale patterns. The results show that the frequency of occurrence of tornado environments has increased in Romania since 1980, especially over southeastern Romania. This work has been financed within project „Dezvoltarea Centrului de Competență pentru Adaptarea Comunităților Locale la Schimbările Climatice prin parteneriate de tip public-privat în domeniul CDI” cod 3/16.11.2022 finanțat prin Planul Național de Redresare și Reziliență Apel nr.

Influence of Moscow megacity on severe atmospheric convective events: results of high-resolution modeling for multiple summers
Authors: Platonov Vladimir , Chernokulsky Alexander V. , Varentsov Mikhail , Shikhov Andrey , Yarinich Yulia
Published: March 2023

During the warm season in the Moscow region, severe convective events like squalls, heavy showers, large hail, and tornadoes are regularly observed. Moscow megacity may intensify such phenomena due to various urban effects including modulation of heat and moisture fluxes. To quantitatively estimate this effect, we used datasets from two long-term numerical experiments based on the high-resolution COSMO-CLM mesoscale model (grid size ~1 km, output step 1 hour) for the summer seasons of 2007–2016. Experiments differ by switching on/off the urban canopy layer parameterization of TERRA_URB (labeled as URB and noURB, respectively).

We analyzed the maximum surface wind speed, the vertical component of wind speed at different levels, the hourly intensity and daily precipitation amount, and high quantiles for wind and precipitation. To analyze the possibility of mesocyclones formation, we used the Updraft Helicity (UH25) parameter.

We revealed statistically significant differences between the two experiments for the distributions of intense precipitation, vertical wind speed, and the UH25 parameter. The URB experiment showed an increase of the highest quantiles, standard deviations and partially mean values directly above Moscow and to the northeast of the city, in the leeward region compared to the noURB experiment. The compound events were analyzed as well (when both extreme precipitation and extreme surface wind speeds were noted). We found a statistically significant growth of compound events frequency for URB sample and inside the 18-km radius around the center of Moscow indicating the influence of the city.
A machine learning approach to mitigate problems with estimated winds in severe thunderstorm wind damage reports

Published: March 2023

In the United States, the official database of severe thunderstorm wind reports arguably has more serious deficiencies than those of tornadoes and hail. Roughly 90% of the thunderstorm wind reports in the Storm Events database during the period 2007-2021 are estimates without any nearby measurement, and the fact that 40% of the estimates have a value of exactly 50 knots compared to only 13% of the measurements strongly suggests that many may be overestimates since 50 knots is the minimum threshold to be considered a severe wind.   The problems in the database negatively impact development of new forecasting tools and verification.  We have tested six different machine learning approaches, training on roughly 20,000 measured reports during 2007-2017 to create a tool that assigns a probability that any severe thunderstorm wind report is due to winds of 50 knots or greater.  Training is based on date, time, location, and episode and event narrative data from the Storm Events database along with 31 near-storm weather parameters from the Storm Prediction Center mesoanalysis output.  In addition, population density and elevation are used.  Land use and radar reflectivity were also tested but found to not improve the performance. The best-performing algorithm, the Stacked Generalized Linear Model has been found to show large skill with Areas Under ROC curves as high as .90 and Brier Scores around 0.1.  When a supplemental sub-severe database is added for testing, reliability is shown to be good.  Subjective evaluations from testing during three years of NOAA Hazardous Weather Testbed Spring Forecast Experiments have been favorable and will be discussed, along with implications for forecasters.  A recent test found that the average probability for estimated 50 knot wind reports is only 57% whereas it is 81% for measured 50 knot reports, supporting the view of many forecasters that overestimates are a large problem among the estimated reports in the database.
Influence of the Orography of West-Central European Low Mountain Ranges on the Intensity of Deep Moist Convection
Authors: Sperschneider Aaron , Bott Andreas
Published: March 2023

Deep moist convection comes in many different forms and degrees of organization while producing a wide spectrum of severe weather. It is long known that orography can influence the appearance of deep moist convection. In this work, which is based on the bachelor thesis of the first author, we examine whether and to what extent orography influences the intensity of deep moist convection. Therefore, two case studies with typical single cell environments (weak shear and little synoptic forcing) are simulated using COSMO-DE, a numerical weather prediction model provided by the German Weather Service (Deutscher Wetterdienst, DWD). The simulations were performed with a grid spacing of 2.8 km with a temporal resolution of 15 min. In both cases deep moist convection occurred over western Germany, Belgium and The Netherlands over low mountain ranges (below 1000 m) and over adjacent lowlands. In order to investigate the influence of the orography on the simulated deep moist convective cells, maximum updraft speed and maximum precipitation rate over the cells’ lifetime was analyzed. The intensity of the convective cells located over the low mountain ranges is compared to that of the convective cells located over the lowlands. The results show that convective cells over the mountain ranges differ to convective cells over the lowlands. However, these differences are small, if an additional initiation mechanism on the larger scale such as a convergence line is in place. In contrast, major intensity differences occur if there is no such larger scale initiation mechanism. In this case, the deep moist convection is far more intense over the low mountain ranges compared to the lowlands, which provides an important result for nowcasting and forecasting of deep moist convection in these regions and to assess whether convective cells might reach severe weather criteria or not. In addition to these results of the first author's bachelor thesis, recent simulations performed with the Cloud Model 1 (CM1) of the National Center for Atmospheric Research (NCAR) are also presented. Idealized simulations of the two cases with a higher spatio-temporal resolution were examined with regard to updraft speeds and precipitation rates of the simulated cells.
Contrasting impacts of humidity on the ozonolysis of monoterpenes: insights into the multi-generation chemical mechanism
Authors: Zhang Shan , Du Lin , Yang Zhaomin , Tchinda Narcisse Tsona , Li Jianlong , Li Kun
Published: March 2023

Abstract. Secondary organic aerosol (SOA) formed from the ozonolysis of biogenic monoterpenes is a major source of atmospheric organic aerosol. It has been previously found that relative humidity (RH) can influence the SOA formation from some monoterpenes, yet most studies only observed the increase or decrease in SOA yield without further explanations of molecular-level mechanisms. In this study, we chose two structurally different monoterpenes (limonene with an endocyclic double bond and an exocyclic double bond, Δ3-carene with only an endocyclic double bond) to investigate the effect of RH in a set of oxidation flow reactor experiments. We find contrasting impacts of RH on the SOA formation: limonene SOA yield increases by ~100 % as RH increases, while there is a slight decrease in Δ3-carene SOA yield. By analyzing SOA chemical composition and reaction mechanisms, the enhancement in limonene SOA yield can be attributed to the water-influenced reactions after ozone attack on the exocyclic double bond of limonene, which leads to the increment of lower volatile organic compounds under high RH condition. However, as Δ3-carene only has an endocyclic double bond, it cannot undergo such reactions. This hypothesis is further proved by the SOA yield enhancement of β-caryophyllene, a sesquiterpene that also has an exocyclic double bond. These results greatly improve our understanding of how water vapor influences the ozonolysis of biogenic organic compounds and subsequent SOA formation processes.
Model-driven reverse engineering of software processes managing business object relationships in an enterprise system
Authors:   , Paul Jessica
Published: March 2023

Traditionally enterprise software systems have been designed and developed with a monolithic architecture, consisting of a central database managing thousands of business objects. To make such systems suitable for modern distributed computing environments we must first identify these objects, and their lifecycles and interdependencies. This thesis shows how to do so by formally defining the possible lifecycle relationships between business objects, by developing an automatable process for extracting objects and their dependencies from enterprise system program code, and by demonstrating the solution's effectiveness on a large-scale Enterprise Resource Planning.

An exploration of radiographer decision-making regarding rejected or sub-optimal plain x-ray images
Authors:   , O'Keefe Katrina
Published: March 2023

Radiographers acquiring x-ray images are responsible for accepting or rejecting images based on technical image quality criteria. This research explored radiographer decision-making regarding other non-technical parameters for rejecting or accepting images, including radiographer experience, gender and emotional state (at the time of imaging), and patient presentation and age. Radiographer decision making was correlated with a reporting radiologist. Radiographer emotional state was found to be a significant predictor of rejecting images (odds ratio = 4.97, 95% CI 1.4 – 17.3, p = 0.012). Radiographer-radiologist correlation was ‘minimal’ (Kappa = 0.221, p = 0.016).
