Consideration of changes in the local climate in the region of the reservoir and lower pool of hydroelectric stations

Abstract

The positive and negative effects of large hydroelectric power plant reservoirs located in various physiographic zones of the Soviet Union on the local climate were characterized. These effects occur due to an increase in the volume of the water mass having a greater heat capacity and an increase of the area of the water surface compared with the river in an unregulated state. Comparisons were drawn between reservoirs in mountainous and plain territories and in northern and southern zones of the country. Warming and humidity trends along with extensions of frost-free periods into the colder seasons were assessed. The creation of large reservoirs in the southern zone of the Asian part of the country was determined to make the desert and steppe territories suitable for animal habitation. The impact of favorable climatic conditions on recreational development was also assessed.
