In Ukraine, the consequences of climate change are exacerbated by military aggression Russian Federation (RF) not only in temporarily occupied territories but also for entire country, since all resources primarily directed at strengthening defense capabilities and confronting enemy. Nevertheless, has stopped rather intensified recent years. At same time, due to massive targeted shelling RF, almost generating capacities thermal power plants Ukraine have been destroyed, largest hydroelectric...
ABSTRACT In this work, we present results of the development an observation‐based gridded climate dataset (ClimUAd), which covers territory Ukraine for period 1946–2020. The spatial resolution developed data is 0.1° × (approximately 10 km in both longitude and latitude directions), with a 1‐day time step. Four essential variables are included dataset, namely daily sums atmospheric precipitation minimum, mean, maximum air temperature. created product based on complete collection station...
Abstract In this paper we present the results of quality control and homogenization procedures applied to long time series daily atmospheric precipitation sums (Rr) mean (Tm), maximum (Tx) minimum (Tn) air temperature collected in Ukraine. The data from 178 meteorological stations covering period 1946–2020 were analysed. order perform a thorough assurance check, used R package INQC, while Climatol software was detect remove breaks series. INQC tests revealed relatively small number erroneous...
In this contribution, we present the results of development long gridded climate time series, which cover territory Ukraine for period 1946-2020 (75 years). The spatial resolution developed data is 0.1o×0.1o (approximately 10 km in both longitude and latitude directions), while their discreteness 1 day. Four essential variables are included dataset, namely daily sums atmospheric precipitation minimum, mean maximum air temperature. created product based on complete collection weather...
The research deals with the structure of temporal changes in rainfall intensity and spatial distribution magnitude within separate processes fallout dangerous heavy rainfalls warm season. analysis based on data from Ukrainian hydrometeorological observation network (2005-2017) obtained during a special scientific experiment (Kyiv, Bagrynova Mt., period 1969). It has been determined 97 cases such rainfalls, characteristics their distribution, seasonal daily variations. For individual...
Precipitation detailed characteristics, namely spectrum of particles by their sizes, phase and precipitation intensity with high-resolution timestep, still need to be investigated due the complexity direct instrumental measurements but necessity for improving forecast different applications including hydrological emergency service. Our study is focused on stratiform associated cloud system (Ns-As) warm front during prolonged intense event 25th October 2023 in Kyiv, Ukraine. This was...
West Antarctica and the Antarctic Peninsula are considered to be climate tipping point regions where change processes can cause irreversible impacts. The region has a unique ecosystem, which harmfully affected by these changes. In past decades have from Pacific mid-latitudes specifically atmospheric rivers, accompanied mixed-phase clouds precipitation, lead surface melt on both sides of Peninsula. This study focused intense precipitation events during winter in Southern Hemisphere 2022...
The paper presents projections for the balanced scenario A1B of specialized climatic indicators heating period territory Ukraine decades until middle 21st century. Prediction mean temperature, duration and degree-days are based on calculations previously formed adapted to ensemble 10 regional climate models from European project ENSEMBLES. main calculated all nodes a regular grid 25×25 km were verified by E-Obs data 2001―2010. A negligible bias in temperature (in average less than 0.01°C) an...
The field of precipitation the plain territory Ukraine is investigated according to data evenly spaced 18 weather stations. annual analyzed for periods different duration (from beginning observations at station until 2015) and period 1961-2015. main statistical characteristics are calculated, patterns their changes in study area shown. Gradient decrease multi-year 1961-2015 (650 400 mm) directed from northwest south southeast country. value positive skewness kurtosis, coefficient variation...
The research investigates atmospheric precipitation, which according to Ukrainian national regulation has reached the criteria of heavy (≥ 50 mm at ≤ 12 hours) and dangerous (15 – 49 hours). A total 98 cases precipitation (2005 2018), 14 (2017 2018) were analyzed. focuses on formation conditions volumes surface runoff that forms various types underlying surface. To obtain a statistically valid classification, cluster analysis was carried out. allowed distinguish three blocks or clusters, one...
Intense moist intrusions originating from the lower latitudes of Pacific Ocean have been found to a significant impact on Antarctic Peninsula (AP), including enhancement surface melt events, increased runoff, reduction in sea-ice cover and ice shelves destabilization. Clouds play an important role energy budget during these events precipitation formation. Precipitation phase amounts determine local regional mass budget. Our  research focuses cloud microphysical dynamic...
In our work, we analyzed modern software products that are frequently used for quality control and homogenization of long climatological time series different variables, in particular, atmospheric precipitation. Based on analysis, the HOMER was selected to perform procedures monthly precipitation sums. The advantages using include possibility researcher make a decision confirming breakpoints at stage joint comparison (joint detection), which allows considering available information about...
<p>Antarctic Peninsula climate is a very sensitive system that strongly affected by the temperature increase, compared to other Antarctic regions. Moisture transport from lower latitudes influences this region indirectly through precipitation, radiative forcing, and heat advection. Our understanding of factors responsible for enhanced moisture its impact on surface energy balance incomplete, particularly, regarding cloud precipitation microphysics their temporal evolution....
The main focus of this study was to establish the feasibility working with intensity data individual events very heavy precipitation (50 mm or more in 12 hours less) observed over territory Ukraine using remote sensing (satellite GPM IMERG), as well verification satellite ground station (self-recording rain gauge data). consisted processing and maps – IMERG products, building tables graphs based on them, calculating statistical indices evaluating them. A total 7 parameters were involved,...
