Lagrangian transport simulations using the extreme convection parameterization: an assessment for the ECMWF reanalyses
Authors: Hoffmann Lars , Konopka Paul , Clemens Jan , Vogel Bärbel
Published: July 2023

Abstract. Atmospheric convection plays a key role in tracer transport from the planetary boundary layer to the free troposphere. Lagrangian transport simulations driven by meteorological fields from global models or reanalysis products, such as the European Centre for Medium-Range Weather Forecasts' (ECMWF's) ERA5 and ERA-Interim reanalysis, typically lack proper explicit representations of convective updrafts and downdrafts because of the limited spatiotemporal resolution of the meteorology. Lagrangian transport simulations for the troposphere can be improved by applying parameterizations to better represent the effects of unresolved convective transport in the global meteorological reanalyses. Here, we implemented and assessed the effects of the extreme convection parameterization (ECP) in the Massive-Parallel Trajectory Calculations (MPTRAC) model. The ECP is conceptually simple. It requires the convective available potential energy (CAPE) and the height of the equilibrium level (EL) as input parameters. Assuming that unresolved convective events yield well-mixed vertical columns of air, the ECP randomly redistributes the air parcels vertically between the surface and the EL if CAPE is present. We analyzed statistics of explicitly resolved and parameterized convective updrafts and found that the frequencies of strong updrafts due to the ECP, i.e., 20 K potential temperature increase over 6 h or more, increase by 2 to 3 orders of magnitude for ERA5 and 3 to 5 orders of magnitude for ERA-Interim compared to the explicitly resolved updrafts. To assess the effects of the ECP on tropospheric tracer transport, we conducted transport simulations for the artificial tracer e90, which is released globally near the surface and which has a constant e-folding lifetime of 90 d throughout the atmosphere. The e90 simulations were conducted for the year 2017 with both ERA5 and ERA-Interim. Next to sensitivity tests on the choice of the CAPE threshold, an important tuning parameter of the ECP, we suggest a modification of the ECP method, i.e., to take into account the convective inhibition (CIN) indicating the presence of warm, stable layers that prevent convective updrafts in the real atmosphere. While ERA5 has higher spatiotemporal resolution and explicitly resolves more convective updrafts than ERA-Interim, we found there is still a need for both reanalyses to apply a convection parameterization such as the ECP to better represent tracer transport from the planetary boundary layer into the free troposphere on the global scale.

Published: July 2023

Abstract. Low-level (cloud tops below 2 km) mixed-phase clouds are important in amplifying warming in the Arctic region through positive feedback in cloud fraction, water content and phase. In order to understand the cloud feedbacks in the Arctic region, good knowledge of the vertical distribution of the cloud water content, particle size and phase is required. Here we investigate the vertical extent of the cloud-phase and ice-phase optical properties in six case studies measured in the European Arctic during the ACLOUD campaign. Late spring- and summertime stratiform clouds were sampled in situ over pack ice, marginal sea ice zone and open-ocean surface, with cloud top temperatures varying between −15 and
−1.5 ∘C. The results show that, although the liquid phase dominates the upper parts of the clouds, the ice phase was frequently observed in the lower parts down to cloud top temperatures as warm as −3.8 ∘C.
In the studied vertical cloud profiles, the maximum of average liquid phase microphysical properties, droplet number concentration, effective radius and liquid water content, varied between 23 and 152 cm−3, 19 and
26 µm, 0.09 and 0.63 g m−3, respectively.
The maximum of average ice-phase microphysical properties varied between 0.1 and 57 L−1 for the ice number concentration, 40 and 70 µm for the effective radius, and 0.005 and 0.08 g m−3 for the ice water content. The elevated ice crystal number concentrations and ice water paths observed for clouds, with cloud top temperatures between −3.8 and −8.7 ∘C can be likely attributed to secondary ice production through rime splintering.
Low asymmetry parameters between 0.69 and 0.76 were measured for the mixed-phase ice crystals with a mean value of 0.72.
The effect of the ice-phase optical properties on the radiative transfer calculations was investigated for the four cloud cases potentially affected by secondary ice production. Generally the choice of ice-phase optical properties only has a minor effect on the cloud transmissivity and albedo, except in a case where the ice phase dominated the upper cloud layer extinction. In this case, cloud albedo at solar wavelengths was increased by 10 % when the ice phase was given its measured optical properties instead of treating it as liquid phase.
The presented results highlight the importance of accurate vertical information on cloud phase for radiative transfer and provide a suitable data set for testing microphysical parameterizations in models.

Published: July 2023

Abstract. The shallow-water hydrothermal vents (SVs) located off Kueishan (KS) Island, Taiwan, are one of the world's most intensively studied vent systems. It has long been known that white vents (WVs) and yellow vents (YVs) differ in the color and composition of the vent plumes. The endemic vent crabs (Xenograpsus testudinatus) are abundant in both vent types, and ovigerous females migrate to the vent periphery with a distance of 100–200 m to release their offspring. However, most research on the vent crabs was associated with WV or unspecified vent areas. To increase our knowledge of the crabs dwelling in other vent types, we compared the feeding habits of the vent crabs living in WV and YV with 2 sampling months. Specifically, we examined the benthic community of WV and YV, the isotopic niche width, and protein expression patterns of the crabs from the two vents at a distance of 100 m and sampled in July and August 2010. The coverage of sessile organisms and low-mobility fauna in WV was more abundant than in YV, based on the survey in August 2010. The
δ13C and δ15N values of crabs differed spatially
and temporally (multivariate analysis of variance test; p<0.05). The niche width of the vent crabs from YV-August (0.88 ‰2) narrowed substantially compared to the rest, i.e., YV-July (2.94 ‰2), WV-July (2.88 ‰2), and WV-August (3.62 ‰2; p<0.05), respectively. Based on the protein expression patterns, the vent crabs exhibited three groups, i.e., WV-July and YV-July, WV-August, and YV-August, respectively. Our results indicated that the dwelling crabs were associated with their living vent, and within-vent variability was more noticeable in YV compared to WV. We suggested that vent crabs inhabit their resident vent. Even at a scale of meters, trans-vent movement is probably rare as an adaptation to minimize predation risk.
Revisiting and attributing the global controls over terrestrial ecosystem functions of climate and plant traits at FLUXNET sites via causal graphical models
Authors: Shi Haiyang , Luo Geping , Hellwich Olaf , Kurban Alishir , De Maeyer Philippe , Van de Voorde Tim
Published: July 2023

Abstract. Using statistical methods that do not directly represent the causality
between variables to attribute climate and plant traits as controlling ecosystem
functions may lead to biased perceptions. We revisited this issue using a
causal graphical model, the Bayesian network (BN), capable of quantifying
causality by conditional probability tables. Based on expert knowledge and
climate, vegetation, and ecosystem function data from the FLUXNET flux
stations, we constructed a BN representing the causal relationship of climate–plant-trait–ecosystem functions. Based on the sensitivity analysis
function of the BN, we attributed the control of climate and plant traits
over ecosystem functions and compared the results with those based on random
forests and correlation analysis. The main conclusions of this study
include the following: BN can be used for the quantification of causal relationships
between complex ecosystems in response to climate change and enables the
analysis of indirect effects among variables. The causality reflected in the
BN is as good as the expert knowledge of the causal links. Compared to BN,
the feature importance difference between “mean vapor pressure deficit and
cumulative soil water index” and “maximum leaf area index and maximum
vegetation height” reported by random forests is higher and can be
overestimated. With the causality relation between correlated variables
constructed, a BN-based sensitivity analysis can reduce the uncertainty in
quantifying the importance of correlated variables. The understanding of the
mechanism of indirect effects of climate variables on ecosystem functions
through plant traits can be deepened by the chain casuality quantification
in BNs.
Diabatic effects on the evolution of storm tracks
Authors: Marcheggiani Andrea , Spengler Thomas
Published: July 2023

Abstract. Despite the crucial role of moist diabatic processes in midlatitude storm tracks and related model biases, we still lack a more complete theoretical understanding of how diabatic processes affect the evolution of storm tracks. To alleviate this shortcoming, we investigate the role of diabatic processes in the evolution of the Northern Hemispheric storm tracks using a framework based on the tendency of the slope of isentropic surfaces as a measure of baroclinic development. We identify opposing behaviours in the near-surface and free troposphere for the relationship between the flattening of the slope of isentropic surfaces and its restoration by diabatic processes. Near the surface (900–800hPa), cold air advection associated with cold air outbreaks initially acts to flatten isentropic surfaces, with air–sea interactions ensuing to restore surface baroclinicity. In the free troposphere (750–350hPa), on the other hand, diabatic generation of slope of isentropic surfaces precedes its depletion due to tilting by eddies, suggesting the primary importance of moist diabatic processes in triggering subsequent baroclinic development. The observed phasing of the diabatic and tilting tendencies of the slope is observed both in upstream and downstream sectors of the North Atlantic and North Pacific storm tracks, rendering the phasing a general feature of midlatitude storm tracks. In addition, we find a correspondence between the diabatic generation of slope of isentropic surfaces and enhanced precipitation as well as moisture availability, further underlining the crucial role of moisture and moist processes in the self-maintenance of storm tracks.
A coarse pixel scale ground "truth" dataset based on the global in situ site measurements to support validation and bias correction of satellite surface albedo products

Published: July 2023

Abstract. In situ measurements from sparsely distributed networks worldwide are a valuable source of the reference data for validating or correcting the bias of satellite products. However, the significant differences in spatial scale between in situ and satellite measurements make them incomparable except for that the underlying surface of in situ sites is absolutely homogeneous. Instead, in site measurements need to be upscaled to be matched with satellite pixel. Based on the upscaling model we proposed as well as the consideration that in-situ observation generally lacks spatial representativeness due to the widely distributed spatial heterogeneity, we have developed a coarse pixel-scale ground "truth" dataset based on ground measurements of 368 in situ sites from the sparsely distributed observation networks. Furthermore, the effectiveness of the dataset was carefully evaluated over the sites with different degrees of spatial representativeness. The results demonstrate that using this dataset in validation outperforms the direct comparison between satellite and in situ site measurements. The accuracy of the reference data employed for validation or bias correction can be enhanced by 3.5 % overall with this dataset. But the performance of the dataset show dependence on the degree of spatial heterogeneity. Specifically, the improvement of accuracy was the most significant over the regions with strong spatial heterogeneity, with the accuracy of reference data enhanced by 7.3 %. To the best of our knowledge, this dataset is unique in providing coarse pixel scale ground truth with the widest spatial distribution and longest time series. Its ability to capture both spatial and temporal variations of surface albedo at coarse spatial scales makes it an invaluable resource for validating and correcting global surface albedo products.
A new simplified parameterization of secondary organic aerosol in the Community Earth System Model Version 2 (CESM2; CAM6.3)
Authors: Jo Duseong S. , Tilmes Simone , Emmons Louisa K. , Wang Siyuan , Vitt Francis
Published: July 2023

Abstract. The Community Earth System Model (CESM) community has been
providing versatile modeling options, with simple to complex chemistry and
aerosol schemes in a single model, in order to support the broad scientific
community with various research interests. While different model
configurations are available in CESM and these can be used for different
fields of Earth system science, simulation results that are consistent
across configurations are still desirable. Here we develop a new simple
secondary organic aerosol (SOA) scheme in the Community Atmosphere Model
(CAM) version 6.3, the atmospheric component of the CESM. The main purpose
of this simplified SOA scheme is to reduce the differences in aerosol
concentrations and radiative fluxes between CAM and CAM with detailed
chemistry (CAM-chem) while maintaining the computational efficiency of CAM.
CAM simulation results using the default CAM6 and the new SOA schemes are
compared to CAM-chem results as a reference. More consistent SOA
concentrations are obtained globally when using the new SOA scheme for both
temporal and spatial variabilities. The new SOA scheme shows that 62 % of grid
cells globally are within a factor of 2 compared to the CAM-chem SOA
concentrations, which is improved from 24 % when using the default CAM6
SOA scheme. Furthermore, other carbonaceous aerosols (black carbon and
primary organic aerosol) in CAM6 become closer to CAM-chem results due to
more similar microphysical aging timescales influenced by SOA coating,
which in turn leads to comparable wet deposition fluxes. This results in an
improved global atmospheric burden and concentrations at the high latitudes
of the Northern Hemisphere compared to the full chemistry version
(CAM-chem). As a consequence, the radiative flux differences between
CAM-chem and CAM in the Arctic region (up to 6 W m−2) are significantly
reduced for both nudged and free-running simulations. We find that the CAM6
SOA scheme can still be used for radiative forcing calculation as the high
biases exist both in pre-industrial and present conditions, but studies
focusing on the instantaneous radiative effects would benefit from using the
SOA scheme developed in this study. The new SOA scheme also has technical
advantages including the use of identical SOA precursor emissions as
CAM-chem from the online biogenic emissions instead of pre-calculated
emissions that may introduce differences. Future parameter updates to the
CAM-chem SOA scheme can be easily translated to the new CAM SOA scheme as it
is derived from the CAM-chem SOA scheme.
Brief communication: Is vertical shear in an ice shelf (still) negligible?
Authors: Miele Chris , Bartholomaus Timothy C. , Enderlin Ellyn M.
Published: July 2023

Abstract. Vertical shear is recognized today as a key component of the stress balance of ice shelves. However, the first ice shelf models were built on the neglect of vertical shear. Partly due to its historical treatment, it remains common to discuss vertical shear as though it were still considered negligible in ice shelf models. Here, we offer a historical perspective on the changing treatment of vertical shear over time, and we emphasize the term's non-negligibility in current ice shelf modeling. We illustrate our discussion in the simplest context of an analytic, isothermal, shallow-ice-shelf model.
Brief communication: On the definition of the low-level jet

Published: July 2023

Abstract. Low-level jets (LLJ) are examples of non-ideal wind speed profiles affecting wind turbine power production, wake recovery, and structural/aerodynamic loading. However, there is no consensus regarding which definition should be applied for jet identification. In this study we argue that a shear definition is more relevant for wind energy than a falloff definition. The shear definition is demonstrated and validated through development of an ERA5 LLJ climatology for six sites. Identification of LLJ and their morphology, frequency, and intensity is critically dependent on the i) vertical window of data from which LLJ are extracted and ii) the definition employed.

Los confinamientos y distanciamientos por la transmisión del coronavirus en el 2020 aceleraron las transformaciones digitales y provocaron contradictorias conductas y reacciones sociales. En este marco, este artículo analiza los discursos sobre el servicio de delivery que realizaron los venezolanos migrantes durante la pandemia y la nueva normalidad por la COVID-19 en Lima-Perú e identifica los recursos lingüísticos que los cibernautas emplearon en la elaboración de estos. Metodológicamente, esta es una investigación cualitativa de tipo interpretativo que estudia un conjunto de diecisiete tuits principalmente de peruanos y venezolanos sobre el delivery venezolano en Twitter. El artículo concluye que el servicio de delivery generó dos tipos de discursos: de un lado, discursos de discriminación y rechazo, que se repiten en la sociedad peruana y que se plasman en el ciberespacio, y de otro lado, admiración por parte de los venezolanos, quienes destacan también los enfrentamientos que atraviesan frente a la alternativa de un empleo que permitía la sobrevivencia. Dichos razonamientos se revelan a través de las estrategias lingüísticas utilizadas.

Published: July 2023

This study investigates the influence of sustainable practices in human resources on employee environmental performance by exploiting environmental maturity and proactiveness. Ability-motivation-opportunity theory was utilized as the theoretical foundation for this endeavour. Social Exchange Theories provide a significant basis for supporting the framework. Data was gathered from employees working in Pakistani private sector banks within the Punjab district Sahiwal. An organized questionnaire was utilized to collect data, while a self-administered survey was administered to gather information. Three hundred questionnaires were distributed among respondents; 254 could be completed for further analysis; 55 surveys were returned as eligible responses. This study helps human resource professionals better appreciate the role played by proactive environmental management. Studies of the effects of green practices in human resource management on employee environmental performance within the banking industry can play an integral part in making decisions about it. Unfortunately, many human resource managers in Pakistani banks don't fully appreciate how green practices impact employee sustainability in this industry.

Procesje parafialne i klasztorne w oktawie Bożego ciała w dziewiętnastowiecznym Krakowie (1795-1918)
Authors: Fedorowicz Szymon
Published: July 2023

Najstarsze procesje organizowane z okazji tego święta sięgające XIV wieku opuściły katedrę, ale te procesje pomijam w tej rozprawie. Jednak procesje z poszczególnych kościołów (według najstarszych źródeł z XVI w.) były połączone z procesją katedralną, natomiast w oktawie Bożego Ciała szły oddzielnie do kościoła kazimierskiego pod wezwaniem Bożego Ciała. Tradycja ta była niepraktyczna i dokuczliwa, więc starano się wprowadzić nowe praktyki, ale nie zostały one zaakceptowane. W tej poważnej sytuacji biskup Załuski dokonał radykalnych zmian koncepcyjnych i organizacyjnych i wprowadził je dekretem. Wprowadził też wiele dekretów dyscyplinarnych i porządkowych, aby procesje te stały się bardziej liturgiczne i bardziej wyraziste. Harmonogram procesji w tym uroczystym tygodniu wraz z deklaracją późniejszej praktyki XIX wiecznej znajduje się w załączonym wykresie. Harmonogram ten pokazuje, jak uroczysty charakter miała oktawa Bożego Ciała w Krakowie. Nie wszystkie procesje cieszyły się popularnością wśród wiernych, nie wszystkie miały tę samą oprawę, ale niektóre z nich miały charakter religijny i ludowy. Jedną z nich była procesja maryjna i dominikańska, ponieważ ich trasa przebiegała wokół Rynku, jako procesja wawelska. Jeśli wierzyć w słowa kronikarzy, te nabożeństwa zgromadziły rzesze ludzi. Pozostałe procesje nie były tak znaczące, zwłaszcza pod koniec omawianego okresu, ponieważ prawie każdy kościół miał swoją procesję. Ich trasy ograniczały się do ulic przylegających do konkretnego kościoła. Zachowane materiały archiwalne ujawniają niekiedy szczegółowe i ciekawe informacje, ale nie pozwalają na odtworzenie całego obrazu tych obchodów.

Ductal carcinoma in situ (DCIS) is a breast carcinoma (BC) consisting of malignant cells in the ductal lumen of the breast without invasion beyond the epithelial membrane. The article presents a rare clinical case of the combined course of chronic mastitis and ductal carcinoma in situ in a 47-year-old female patient who was diagnosed with chronic mastitis during instrumental examination, and only after trepan biopsy and subsequent histological examination, intraductal breast cancer in situ was verified. This may indicate that instrumental methods and techniques are insufficiently informative in diagnosing ductal carcinoma in situ against the background of chronic mastitis.

Introducion: Spasticity is persistent increased muscle resistance to joint movement. Treatments for this condition aim to prevent or minimize its evolution into severe movement restrictions. Among the therapeutic options are the use of oral medications or the surgical approach for continuous baclofen infusion, in which two forms of administration can be used: intraventricular or intrathecal. However, the intraventricular approach has been replaced by the intrathecal approach in most cases, making it necessary to investigate in the literature the possible reasons for such a change. Perhaps it is a forgotten therapy? Objectives: The present paper aims to address spasticity, as well as review the main indications and results of the use of intraventricular baclofen when compared to the intrathecal approach. Methods: This is an integrative literature review. The database used was PubMed. Using the terms “Baclofen”, “Intraventricular”, “Intratecal” and “Spasticity”, associated with the Boolean term “AND” to direct the search. Articles from the last five years that addressed the intraventricular and intrathecal techniques of baclofen administration were included. Discussion: Spasticity has several forms of surgical treatment. The intraventricular approach is indicated in cases of cerebral palsy, spinal cord injury and stroke, but mainly for cases of dystonia and spasticity refractory to conventional drug treatment. Conclusion: When comparing the use of intraventricular and intrathecal baclofen, the intrathecal approach, despite being a technique used for over 30 years and for similar conditions, is still an effective therapeutic measure with low complication rates, depending on the technique used.

Introduction: Multiple sclerosis (MS) is an inflammatory, immune-mediated disease of the central nervous system, characterized by multifocal areas of demyelination. There is a knowledge gap in understanding the disease, particularly the progressive forms in different regions of the country, such as the Northeast. Objectives: To report the profile of progressive MS at a reference center in Ceará. Methods: This observational and cross-sectional study was conducted through a review of medical records and interviews at a Reference Center for Demyelinating Diseases in the city of Fortaleza, Ceará. Results: From 283 patients with MS diagnosis according to the 2017 McDonald criteria, 36 (12.7%) had progressive phenotype, 20 (56%) secondary progressive and 16 (44%) primary progressive. From those 36 patients currently followed up, 25 (69.4%) were women, 19 (52.8%) were caucasian and 18 (50%) were high educated. The median follow-up time was five years and the peak prevalence was between the 4th and 5th decades. Regarding disability, 27.8% already used support in the first assessment (EDSS 6.0), and in the last assessment, considering the last EDSS recorded, the percentage of patients in need of support almost doubled: 52.8%. Regarding the first disease-modifying drugs (DMD), there was a prevalence of interferons, considering that it was the most used class in the 1990s. Considering the current DMD, there is a prevalence of monoclonal antibodies (47%), with Natalizumab (25%) and Ocrelizumab (22%). In a comparative analysis, there is a drop in the use of interferons (8%). Conclusion: Understanding the clinical-epidemiological profile of MS patients with a progressive phenotype is essential to guide the propaedeutic reasoning, guise the conduct and restructure the dynamics of health services.

Introduction: We present a case of a patient with atypical manifestations of Erdheim-Chester Disease. We aim to describe the neurological manifestations of Erdheim-Chester disease and the main radiologic findings in magnetic resonance imaging. We carried out a literature review in the PubMed and SciELO electronic library databases. Case: 71-year-old men presented with memory loss, inattention and apathy, developed in the last month. Within the symptoms onset, he had ictal episodes of transient loss of conscience, oromastigatory automatisms and right gaze deviation, with daily recurrence. Physical examination revealed disorientation, right hemiparesis and ideomotor dyspraxia. Magnetic resonance imaging revealed subdural laminar collections on the left hemisphere, with focus of restricted diffusion, thickening of the pachymeninges and also a nodular lesion in the left posterior corona radiata, with granulomatous aspect. Cerebrospinal fluid analysis showed lynphomonocytic pleocytosis (26 cels) and high protein (229 mg/dL). A meningeal biopsy was performed and the anatomopathological examination showed lymphoplasmocytic and histiocytic infiltrate with xanthomized histiocytes, positive for CD68, negative for CD1a and Protein S-100. At this point, we made a diagnosis of Erdheim-Chester disease. Discussion: Erdheim-Chester disease is a non-Langerhans histiocytosis with diverse clinical manifestations. Neurological symptoms include headache, motor deficit, ataxia, encephalopathy and seizures. Radiologic features are heterogeneous, including tumoral, vascular and pseudodegenerative presentations, as well as pachymeningitis and subdural collections. Conclusion: Erdheim Chester disease has multiple neurological presentations and must be considered as a differential diagnosis in the setting of pachymeningitis and granulomatous solid lesions.
