The present study is aimed at the development of a novel empirical base for application to ground-based astronomical telescopes. A Weather Research and Forecasting (WRF) model used description atmospheric flow structure with high spatial resolution within Baikal Astrophysical Observatory (BAO) region. Mesoscale vortex structures are found boundary layer, which affect quality images. results simulations show that upward air motions in lower atmosphere suppressed both above cold surface Lake...
The spatial structure of land use and biophysical characteristics surface (albedo, leaf index, vegetation cover) are updated using the GLASS (Global Land Surface Satellite) GLC2019 Cover, 2019) modern satellite databases for mesoscale numerical weather prediction with WRF model territory Belarus. series WRF-based experiments was performed to verify influence on forecast quality some difficult predict winter cases. initialized by GFS Forecast System, NCEP) global model. It is shown that...
Two approaches are proposed for updating the geophysical characteristics of surface (land use, albedo, leaf index, fraction absorbed photosynthetically active radiation) in Weather Research and Forecasting (WRF) numerical model territory Belarus: monthly averages based on modern Earth remote sensing databases GLASS (Global Land Surface Satellite), GLC2019 Cover, 2019); daily update operational MODIS satellite composite products. To estimate impact initial data quality prediction temperature,...
The problem of improving the WRF numerical weather model performance for territory Belarus by assimilating Earth remote sensing data is considered. It shown that winter period, use satellite high spatial resolution, including on structure land , albedo, leaf index and photosynthetically active radiation absorbed underlying surface can reduce a root-mean-square error short-term forecast (up to 48 h) air temperature 0.53–1.11 °С. For summer basis experiments optimal correction factor albedo...
The article presents a quantitative estimation of intensity urban “heat islands” in Belarus and their changes as result global warming. potential opportunities for improving the microclimate by increasing area forest park zones city have been evaluated using mesoscale numerical simulation meteorological conditions cities. It is shown that summer, Belarusian regional centers are warmer than suburban areas within 2–3 °С during day 1.2–2.3 at night. Over period has passed since beginning this...
The article discusses the expected climate changes in Belarus as a result of two types land transformation – rewetting degraded peatlands and increasing forest cover. analysis was performed for growing season (May–September) based on long-term Earth remote sensing data, mesoscale modeling atmospheric processes, balance calculations using ERA5 reanalysis. It is shown that waterlogging, daytime temperature underlying surface southern part (below latitude Minsk) decreases within 1.5°С due to...
<p>Heavy precipitation forecast remains one of the biggest problems in numerical weather prediction. Modern remote sensing systems allow tracking rapidly developing convective processes and provide additional data for models practically real time. Assimilation Doppler radar also allows to specify position intensity atmospheric models.</p><p>The primary objective this study is evaluate impact Doppler  reflectivity velocity assimilation...
The forecasts of severe weather events obtained with the WRF numerical mesoscale model adapted system for assimilation reflectivity and radial velocity data from network Belarusian Doppler radars used in Belhydromet 2019 are analysed. A description echo quality control based on radar dual-polarisation characteristics method three-dimensional variational (3D-VAR) to assimilate described. results case studies simulation precipitation strong wind various circulation types Belarus without given....
In this article the study of comfort level climate has been performed on basis analysis spatiotemporal changes bioclimatic indexes: effective temperature, equivalent-effective temperature and air heat content index for period from 1966 to 2020. The increase in average temperatures, decrease wind speed insignificant humidity led improvement weather frequency days with very cold weather. Usually, was less evident mid-seasons than winter summer. total, since late 1970s most significant values...
