Обґрунтовано, що хвиля тепла липня–серпня 2010 р. була найпотужнішою та найтривалішою для східних областей за досліджуваний період. Охарактеризовано синоптичні процеси, що призвели до її формування та температурний режим під час цього метеорологічного феномену.The aims of the study were to determine the frequency of heat wave cases for Eastern regions of Ukraine in the summer months June to August in 1961-2015 and to analyze their duration and intensity. On the basis of 5 selected stations of the meteorological network, daily values of maximum air temperature in the summer months were used to determine heat wave episodes according to the definition recommended by the IPCC. The results indicate that the highest amount of the heat wave episodes Eastern regions occurred at the stations Lozova (31 cases) and Kharkiv (29 cases). In contrast to other decades, the number of heat wave episodes was highest for all stations in the period 2006–2010. The essential differences in the amount of HW events in modern period (1991–2015) and normal climatic period (1961–1990) were found. The amount of HW cases in Donetsk, Lugansk and Lozova in modern period is more than twice higher than during 1961 1990. In Mariupol during normal climatic period was determined only one heat wave, but during period 1991 2015 their amount raised ten times. The mean heat wave duration during researching period was between 7,2 and 9,1 days. The longest HW duration on different stations varied dramatically – from 13 days (in Lozova) to 24 (in Lugansk). For all the stations, the longest heat wave duration occurred at the end of July – first part of August 2010. Also this heat wave was the most intense and characterize by cumulative Ta,max from 51,6°C (in Mariupol) to 127,8°C (in Lugansk). The mean Ta,max for every station varied between 2,9 and 3,1°C, and only in Mariupol this paremeter was much lower – 2,1°C. Thus, was determined that the heat wave which observed at the end of July – first part of August 2010 was the longest and the most intense for Eastern regions of Ukraine during the period 1961–2015. In the article also was analyzed the influence of blocking anticyclone (the center of which was situated above European part of Russian Federation) on the forming this heat wave.ukхвиля теплаінтенсивність хвилі теплатривалість хвилі теплаheat waveheat wave durationheat wave intensityСтаття
