Dynamics of snow cover in Kirovohrad region at the end of the XX and the beginning of the XXI centuries


 Snow cover significantly affects the formation of climate in winter. The snow over has low thermal conductivity, which protects soil from freezing. In spring, moistens and plays an important role surface water regime economic activity country. It should be noted that lack or insufficient height can cause freezing winter crops their death, leads to a decrease even loss yield. Accordingly, increase crop yields depends on proper use cover. purpose research is determine characteristics analyze changes Kirovohrad region late twentieth early twenty-first centuries. Data daily observations at meteorological stations for period 1996 2018 were used as primary information work. established appearance coincides two periods (1961-1990 1996-2018) was observed third decade October almost all stations, except area data distribution Dolynska weather station, where first during 1961-1990 occurred October. disappearance this April, contrast cadaster, 75% snowmelt second while station south March. At Kropyvnytskyi located central part region, both same dates. 1996-2018, values highest decadal peaks lower than climatic norm. frequency winters with different gradations varies greatly study periods. For maximum gradation 1-5 cm; norm greatest recurrence recorded 11-20 cm, significant indicators are 21-30 cm. recurrences 100% determined 0-5 cm cover.
