Effects of Arctic ozone on the stratospheric spring onset and its surface response

Published: July 2022

Abstract. Ozone in the Arctic stratosphere is subject to large interannual variability, driven by both chemical ozone depletion and dynamical variability. Anomalies in Arctic stratospheric ozone become particularly important in spring, when returning sunlight allows them to alter stratospheric temperatures via shortwave heating, thus modifying atmospheric dynamics. At the same time, the stratospheric circulation undergoes a transition in spring with the Stratospheric Final Warming (FSW), which marks the end of winter. A causal link between stratospheric ozone anomalies and FSWs is plausible and might increase the predictability of stratospheric and tropospheric responses on sub-seasonal to seasonal timescales. However, it remains to be fully understood how ozone influences the timing and evolution of the springtime vortex breakdown. Here, we contrast results from chemistry climate models with and without interactive ozone chemistry to quantify the impact of ozone anomalies on the timing of the FSW and its effects on surface climate. We find that ozone feedbacks increase the variability in the timing of the FSW, especially in the lower stratosphere. In ozone-deficient springs, a persistent strong polar vortex and a delayed FSW in the lower stratosphere are partly due to lacking heating by ozone in that region. High ozone anomalies, on the other hand, result in additional shortwave heating in the lower stratosphere, where the FSW therefore occurs earlier. We further show that FSWs in high ozone springs are predominantly followed by a negative phase of the Arctic Oscillation (AO) with positive sea level pressure anomalies over the Arctic and cold anomalies over Eurasia and Europe. These conditions are to a significant extent (at least 50 %) driven by ozone. In contrast, FSWs in low ozone springs are not associated with a discernible surface climate response. These results highlight the importance of ozone-circulation coupling in the climate system and the potential value of interactive ozone chemistry for sub-seasonal to seasonal predictability.
Aerosol cloud interaction in the atmospheric chemistry model GRAPES_Meso5.1/CUACE and its impacts on mesoscale numerical weather prediction under haze pollution conditions in Jing-Jin-Ji in China

Published: July 2022

Abstract. The representation of aerosol-cloud interaction (ACI) and its impacts in the current climate or weather model remains a challenge, especially for the severely polluted region with high aerosol concentration, which is even more important and worthy of study. Here, ACI is first implemented in the atmospheric chemistry model GRAPES_Meso5.1/CUACE by allowing for real-time aerosol activation in the Thompson cloud microphysics scheme. Two experiments are conducted focusing on a haze pollution case with coexisted high aerosol and stratus cloud over the Jing-Jin-Ji region in China to investigate the impact of the ACI on the mesoscale numerical weather prediction (NWP). Study results show that the ACI increases cloud droplets number concentration, water mixing ratio, liquid water path (CLWP), and optical thickness (COT), as a result, improving the underestimated CLWP and COT (reducing the mean bias by 21 % and 37 %, respectively) over a certain subarea by the model without ACI. Cooling in temperature at daytime below 950 hPa occurs due to ACI, which can reduce the mean bias of 2 m temperature at daytime by up to 14 % (~0.6 °C) in the subarea with the greatest change in CLWP and COT. The 24 h cumulative precipitation in this subarea corresponding to moderate rainfall events increases with reduced the mean bias by 18 %, depending on the enhanced melting of the snow by more cloud droplets. In other areas or periods with a slight change in CLWP and COT, the impact of the ACI on NWP is not significant, suggesting the inhomogeneity of the ACI. This study demonstrates the critical role of the ACI in the current NWP model over the severely polluted region and the complexity of the ACI effect.
Doppler spectra from DWD's operational C-band radar birdbath scan: sampling strategy, spectral postprocessing, and multimodal analysis for the retrieval of precipitation processes
Authors: Gergely Mathias , Schaper Maximilian , Toussaint Matthias , Frech Michael
Published: July 2022

Abstract. This study explores the potential of using Doppler (power) spectra from vertically pointing C-band radar birdbath scans to investigate precipitating clouds above the radar. First, the novel birdbath scan strategy for the network of dual-polarization C-band radars operated by the German Meteorological Service (Deutscher Wetterdienst, DWD) is outlined, and a newly developed spectral postprocessing and analysis method is presented. The postprocessing algorithm isolates the weather signal from non-meteorological contributions in the radar output based on polarimetric attributes, identifies the statistically significant precipitation modes contained in each Doppler spectrum, and calculates characteristics of every precipitation mode as well as multimodal properties that describe the relation among different modes when more than a single mode is identified. To achieve a high degree of automation and flexibility, the postprocessing chain combines classical signal processing with clustering algorithms. Uncertainties in the calculated modal and multimodal properties are estimated from the small variations associated with smoothing the measured radar signal. The analysis of five birdbath scans recorded at different radar sites and for various precipitation conditions delivers reliable profiles of the derived modal and multimodal properties for two snowfall cases and for stratiform precipitation above and below the melting layer. To help identify the dominant precipitation growth mechanism, Doppler spectra from DWD's birdbath scans can be used to retrieve the typical degree of riming for individual snow modes. Here, the automatically identified snow modes span a wide range of riming conditions with estimated rime mass fractions of up to RMF > 0.5. The evaluation of Doppler spectra inside the melting layer and for an intense frontal shower, with observed radar reflectivities of up to about 40 dBZ, occasionally shows erroneously identified precipitation modes and spurious results for the calculated higher-order Doppler moments of skewness and kurtosis. Nonetheless, the Doppler spectra from DWD's operational C-band radar birdbath scan provide a detailed view into the precipitating clouds and allow for calculating a high-resolution profile of radar reflectivity, mean Doppler velocity, and spectral width even in intense frontal precipitation.

Abstract. Numerical simulation models that are used to investigate the near-Earth space plasma environment require sophisticated methods and algorithms together with high computational power. Vlasiator is a hybrid-Vlasov plasma simulation code that, as of recent technological developments, has been able to perform 6D (3D in ordinary space and 3D in velocity space) simulations using Adaptive Mesh Refinement (AMR). In this work we describe a side effect of using AMR in Vlasiator where the heterologous grid approach creates resolution induced discontinuities due to the different grid resolution levels. The discontinuities cause spurious oscillations in the electromagnetic fields that alter the global results. We present and test a spatial filtering operator for alleviating this artifact without significantly increasing the computational overhead. We demonstrate the operator's use case in large 6D AMR simulations and evaluate its performance with different implementations.
UVBoost (v0.5): a hybrid radiative transfer and machine learning model for estimating ultraviolet radiation
Authors: de Paula Corrêa Marcelo
Published: July 2022

Abstract. This article presents UVBoost, a hybrid radiative transfer estimator based on a Supervised Machine Learning (SML) regression model powered by high precision ultraviolet radiation (UVR) calculations provided by a conventional Radiative Transference Model (RTM). The proposed regression model takes UVR as a dependent variable, and the Solar Zenith Angle (SZA), Total Ozone Content (TOC), and Aerosol Optical Depth (AOD), as the independent predictive variables. UVBoost was developed to increase computational speed for conducting calculations with large databases, without sacrificing result accuracy. Furthermore, this method employs a user-friendly code, which can be used by laymen or researchers in other areas. UVBoost can be used to disseminate UVR data online anywhere in different spatiotemporal scales, or for climatological projection studies on a global scale. The model was developed by comparing seven regression SML tools via cross validation. These results were validated using non-parametric statistical tests. Of all the tested tools, the Categorical Boosting (CatBoost) method showed the best accuracy at the lowest computational cost. Two additional studies were carried out, one at the global scale, and another at the local scale, to compare the traditional RTM vs. the UVBoost results. The first study simulated a global UVR field (1°x1°), with 64800 grid points, with input data from CMIP6, available at https://pcmdi.llnl.gov/CMIP6/. The differences between the RTM and the UVBoost were less than ±5 % for approximately 95 % of all points, except for points with high SZA. The computational speed of UVBoost surpassed that of the RTM by more than three orders of magnitude. The second study simulated the daily UVR at eight different locations on Earth. The results showed that the UVBoost was very efficient in simulating accumulated UVR doses during the day, with negligible differences (< ±3 %), which means it can be used in studies on UVR and human health. In the future, UVBoost will include other geophysical parameters and be extended to other bands in the electromagnetic spectrum.
Reanalyses of Maskelyne’s Tidal Data at St. Helena in 1761
Authors: Woodworth Philip Leslie , Vassie John McLauchlan
Published: July 2022

Abstract. The construction of an electronic data set of the tidal measurements made at St. Helena in 1761 by Nevil Maskelyne is described. These data were first analysed by Cartwright (1971, 1972) in papers which have importance within studies of changing tides. However, Cartwright’s data files were never archived for the benefit of other researchers, demonstrating that ‘old data’ at risk can sometimes take the form of electronic rather than paper records. In the present paper, the newly digitised Maskelyne data have been reanalysed by several techniques in order to obtain an updated impression of whether the tide has changed at that location in over two and a half centuries. Our main conclusion, consistent with that of Cartwright, is that the major tidal constituent (M2) has changed little. However, the results of the various techniques demonstrate how difficult it is to obtain reliable conclusions for the smaller constituents.
FEOTS: A New Offline Code for the Fast Equilibration of Tracers in the Ocean
Authors: Schoonover Joseph , Weijer Wilbert , Zhang Jiaxu
Published: July 2022

Abstract. In this paper we introduce a new software framework for the offline calculation of tracer transport in the ocean. The Fast Equilibration of Ocean Tracers Software (FEOTS) is an end-to-end set of tools to efficiently calculate tracer distributions on a global or regional sub-domain using transport operators diagnosed from a comprehensive ocean model. To the best of our knowledge, this is the first application of a Transport Matrix Model to an eddying ocean state. We demonstrate the capabilities of FEOTS in an application focused on the Argentine Basin, where intense eddy activity and the Zapiola Anticyclone lead to strong mixing of water masses. The demonstration clearly shows the benefits of the approach, while at the same time highlighting the limitations of the Impulse Response Functions approach in capturing tracer transports by a non-linear advection scheme. Our future work will focus on improving the computational efficiency of the code to reduce time-to-solution, and on using different basis functions to better represent non-linear advection operators.

New data science education programs, which are being launched at a growing rate, are designed for multiple levels, beginning with elementary school pupils. Machine learning is an important element of data science that requires an extensive background in mathematics. While it is possible to teach the principles of machine learning as a black box, it might be difficult to improve algorithm performance without a white box understanding of the underlaying learning algorithms. In this paper, we suggest pedagogical methods to support white box understanding of machine learning algorithms for learners who lack the needed graduate level of mathematics, particularly high school computer science pupils.
Association of Cognitive Learning Style with Attitude towards Science

Published: July 2022

Scientific literacy has become an indispensable modern skill set. For a long time, cognitive psychologists and educators have been focused on the understanding of individual differences and its influence on teaching and motivation to learn science. This research was executed to find the association of Field Dependent- Field Independent cognitive learning styles and attitude towards science. Quantitative approach was used in this research and survey research method was used in it. A sample of 478 undergraduate science students was selected through stratified random sampling from three strata: BS Physics, Mathematics and Biosciences programs. The sample consisted of 158 male and 320 female undergraduate science students. The hypotheses were tested using chi-square , t-test and coefficient of correlation at 95% significance level. The data was collected through standardized test named as “SHAPES” to identify the cognitive learning style of students. The attitude towards science was measured through self-developed tool. The findings revealed that female undergraduate science students were significantly Field Independent and possess greater attitude towards science than Field Dependent undergraduate male science students. Significant relationship was found between attitude towards science and Field Dependent-Field Independent cognitive learning style. It is recommended that educators and curriculum developers focus on student’s individual difference so they can learn according to their respective learning styles. In this way, Field Dependent undergraduate science students may also possess better science related attitude in support of improved academic achievement.

Resilience theory in started of an examination has created into a wide, energetic and energizing field of ponder. Current strength hypothesis addresses people (both children and grown-ups), families, communities, working environments and approaches are connected with human creatures related to social terms and political conditions. There are a few zones of life that have not been touched in one way or another by resistance hypothesis, counting the military community. In this research, analyzing the resilience pretending to impelemntation enterpreneur. This research using bibliometric method by the index of Scopus anda data analyse using the Vosviewer. In enhancing the strategy for developing resilience reveal that an economist uses the term 'standard human capital' to mean that human capital is a resource in people in the form of skills, knowledge and abilities that significantly affect their productive capacity and which determines individual employability. Human Resource Management or is a critical perspective related to resilience theory that is not only included in the company's philosophy but also in the strategic planning process. An example of human resource management is planning, organizing, directing and controlling the procurement, development, compensation, integration, maintenance and termination of labor relations with a view to helping achieve company, individual and community goals

Published: July 2022

The paper evaluates the priorities of the US and China with regards to economic, geopolitical, military technology, and alliance formation. In the economic aspect, we will study China's BRI policy and USA's B3W counter project. The goal of both states in this regard is to dominate the international market. Both the countries are investing in Hyper Sonic technology to gain an upper hand in the Military expanse. The formation of alliances is another clever tactic in the name of establishing mutual security. China's relationship with the US arch-enemy Russia and the Chabahar Port and CPEC projects with Iran and Pakistan respectively appear to be an alarming situation for the US. To counter China's increasing advancement, the US formed QUAD and AUKUS with India, Japan, Australia, and the UK, along with the Reciprocal Access Agreement to limit the escalating approach of China. The blame game between the US and China regarding the COVID-19 pandemic also sparked many controversies. The increased threat perceptions and more crucial political elements between the two powers are dynamics of global hegemony. Analytical and Descriptive methods of research are applied in the paper.

Published: July 2022

Защита и поддержание качества окружающей среды касается каждого, от индивидуального до глобального уровня. Этот процесс должен охватывать все страны мира и все организации в этих странах. С целью привлечения предприятий к охране окружающей среды в последние годы в компаниях ведутся дискуссии об экологическом менеджменте. Многочисленные стандарты и системы управления, определенные на местном, региональном и международном уровнях, усиливают растущее влияние экологического менеджмента. Окружающая среда является одним из ключевых вопросов в Европейском Союзе, где были определены система EMAS (Схема экологического менеджмента и аудита) и группа стандартов ISO 14000, касающихся охраны окружающей среды и отношения компаний к ней. В отличие от системы EMAS, которая является обязательной для членов ЕС, стандарты ISO не являются обязательными, но большинство компаний в ЕС применяют их в своей деятельности. Компании в Республике Сербия, в результате сотрудничества с компаниями из ЕС, часто принимают решение о внедрении этих стандартов, а также для облегчения сотрудничества с иностранными предприятиями, которые часто требуют внедрения этих стандартов. Чтобы выяснить, какое значение сербские компании придают рациональному природопользованию и охране окружающей среды, данное исследование содержит опрос, в ходе которого респонденты указывают, что они не очень верят в ответственное отношение сербских предприятий к окружающей среде. По этой причине необходимо добиться прогресса в этой области в будущем.

Published: July 2022

Несмотря на засушливый климат, в Астраханском регионе нередки сильные ливни и снегопады, приводящие к размыву и

насыщению покровных суглинистых грунтов. В отсутствие организованной системы ливневой канализации в городском хозяйстве происходит затопление дорог и дворовых территорий жилых кварталов. На примере многоэтажного жилого дома с эксплуатируемой кровлей в условиях точечной застройки в центральной части города предлагается оптимальная модель системы ливневой канализации с потенциально загрязненной территории. Применены оригинальные элементы системы открытого водоотвода: монолитные лотки с решетками, водовыпуски, конструкция водоприемного и смотрового колодцев. Выполнен прогноз качественного состава поверхностного стока по основным загрязнителям, подобран фильтр локальной очистки.
