In the paper the results of calculation of the air surface temperature in the viscous layer obtained by the energybalance model of the surface layer “SLEB”, are analyzed. The calculated values of the air surface temperature in the viscous layer are compared with the values of the ground temperature derived from the weather obseravtions. The procedures used provide a good accordance of calculated and measured temperatures. Model “SLAB” is a compoment part of the meteorological preprocessor of the air dispersion model “MLAD”.
A review of the recent scientific investigations carried out in the Russian Hydrometeorological Center is presented. In these contributions the relationship between the quantative characteristics of atmospheric fronts and precipitation is examined by using the results of the numerical experiments for various prognostic models. The methods of the precipitation forecast in which it isn’t necessary to account for the vertical motions and the condensate, are proposed. To estimate the relationship between precipitation and intensity of the atmospheric fronts the synoptic situation with the heavy precipitation observed is studied.
The forecasts of regional climatic models results were verified with the monthly mean temperatures observed at the Ukrainian sites (Odessa, Poltava, Vinnytsia, Simferopol for 1961-2010; Zaporizhzhia, Sumy, Rivne for 1973- 2010). The skill of the models was determined; e.g. for the Odessa, best result was provided by the RACMO ECHAM5-r3 model (KNMI, Netherlands). The model result is conditioned the ability of regional model to reproduce some atmospheric processes as well as the input data
In the article shown that in the past decade has seen an increase amount of heat waves cases of, their intensity and duration. Shown of heat wave determinations, which are used as individual authors, as well as national weather services in different countries. Grounded, that definitions recommended by the WMO is the most convenient for the study of this atmospheric phenomenon in the Ukraine. Describe the consequences of heat waves influence on the human body, plants and animals and potential economic losses due to heat wave exposure.
Prognostic abilities of the different versions of WRF models, including non-hydrostatic (NMM) are compared. Models’ biases of the main meteorological variables in the short-term forecasts are defined, Individual case studies are analyzed. Optimal use of prognostic information to improve the quality of forecasts are shown.
On the example of blocking anticyclone, the vertical profiles of atmospheric energetics are considered. The content of different energies, as well as their conversions and transfers are calculated and analysed.
We study the spatiotemporal variability of different droughts using the standardized precipitation evapotranspiration index with time scales 1, 3, 6, 12 and 24 months for the territory of Eastern Europe during 1951-1980 and 1981-2010. It was found that the maximum number of droughts was registered in the period of global warming, i.e. during 1981-2010 years.
The estimation of change climatic recourse of the Lugansk region was examined in 2011-2030 and 2031-2050 years in connection with the changes of climate in compression by base period 1970-2010 years.
