Summing up the brief meteorological results for April this year, he noted several important points. Almost throughout Ukraine, the second month of the calendar spring turned out to be excessively wet. The amount of precipitation exceeded the norm by 1.5 - 2 times, and in some areas even more than three monthly norms fell (for example, Odessa and some cities in the southeast).
The average air temperature was close to normal in most areas, but more cold days were observed in the western regions, including frosts at night and in the morning.. The highest temperature indicators were recorded in the eastern regions, in the extreme south and in the Crimea.
Based on information from world forecasting centers, as well as the Ukrainian Hydrometeorological Institute, he described some features in the atmospheric circulation that determine the weather in May 2023 in Ukraine and Europe.
In our country, the third month of spring will begin with anticyclonic activity that will cover Central and Eastern Europe. The first two days of May will see predominantly sunny and dry weather throughout the country.. But already from May 3-4, the thermobaric field will begin to turn into a cyclonic one.. As a result of this, a period of rains and cloudy skies should again be expected, lasting several days..
Unusually cool weather expected from May 6 to 10. Frosts are possible on the soil surface and in some places in the air at night. Approximately from May 11-12, a gradual increase in air temperature will begin, but it will still remain below the norm until mid-May.
More intense heat should be expected in the second half of the month. In the third decade of the month in the southern and western regions, the thermometers on some days can reach +30 ° C, the nights will become noticeably warmer. The onset of meteorological summer (at an average daily temperature of +15 °C and above) is also expected in the third decade of May.
Thus, there are obvious prerequisites for a cool, sometimes cold May in Ukraine.. The average monthly temperature is expected to be 1-3 °С below the climatic norm; in the western regions and in the Crimea close to normal. The coldest days are predicted from 5 to 15 May. The amount of precipitation in general for the month will fluctuate near the norm, in some places it may fall more than the norm by 20 - 50%.
The contribution of convective precipitation, which usually has a more local character and has significant differences in intensity, will noticeably increase.. There will be more days with thunderstorms and other dangerous phenomena associated with convection (hail, squalls). In the wind regime, air transfer from the north and northwest will be more often observed in the first half of the month and predominantly variable directions in the second half of May.
Beginning in the last month of spring will not bring the desired warmth. Recall that the weather forecaster gave a weather forecast for May 1-7, 2023.
