Розглянуто вплив фізико-географічних умов на гігрометричну океанічність в окремих регіонах України. Побудовано регресійні моделі показника гігрометричної океанічності залежно від фізико-географічних умов. Оцінено внесок окремих елементів географічного положення в загальну дисперсію розглядуваного показника на території України.
This article is devoted to the hygrometric oceanicity that represents the difference of the sums of atmospheric precipitation during August-October and during May-July. It characterizes differences of change of atmospheric precipitation during the warmest period of the year in various types of climate. The paper studied regularities of spatial distribution of hygrometric oceanicity index in Ukraine for the period 1961-1990 years. The data of 187 weather stations that quite uniformly distributed across the country and represent all its climatic zones were processed.
The degree of influence of components of the geographical environment was estimated using regression analysis techniques. The simple linear regression method was used for the estimation of hygrometric oceanicity depending on the geographical location of individual components of weather station - its longitude, latitude, altitude and average degree of closeness& of the horizon, and the method of multiple linear regression - on the totality of the conditions geographical location of weather stations.
It was found that weather station geographical coordinates and altitudes reveal a significant impact on the &hygrometric oceanicity across the country. The hygrometric oceanicity in most regions of the country decreases from west to east. Its value also decreases with distance from Black sea and Azov sea on the main part of the flat territory of Ukraine and& in Crimean mountains. The vertical gradient of hygrometric oceanicity is about -9.3 mm per 100 m of height. The largest absolute values of the oceanicity (14 mm) occur on the territory of Crimea, and the lowest value (-192 mm) - in Carpathian region&. The regional features of the hygrometric oceanicity distribution are the same to distribution of the unevenness indicator of atmospheric precipitation fall and annual precipitation.
The 3-factor regression model was built for the above elements of& the geographical location. It was determined that the contribution of geographic longitude in the total variance of hygrometric oceanicity is 36.0%, latitude - 27.4%, altitude - 36.5%. Рассмотрено влияние физико-географических условий на гигрометрич&ескую океаничность в отдельных регионах Украины. Построены регрессионные модели показателя гигрометрической океаничности в зависимости от физико-географических условий. Оценен вклад отдельных элементов географического положения в общую дисперсию расс&матриваемого показателя на территории Украины.
