Abstract

The process of upwelling is the rise of cold water masses to the surface of the reservoir and is the subject of study around the world, because this process affects many water parameters. Upwelling increases biological productivity and provides nutrients to marine fauna, partially causes changes in the mass of coastal waters, and the influx of cold water can affect local changes in the climate cycle. In open and closed reservoirs, the process occurs in different ways. The Caspian Sea is a closed reservoir where the upwelling process is observed in the summer. In the article, based on satellite data of sea surface temperature, as well as local data on wind speed and direction, the phases of upwelling in the Kazakh part of the Caspian Sea, which occurred in the period from June 5 to August 22, 2017, are determined. The influence of constant North and North-East winds on the stages of upwelling development is shown, the spatial and temporal scales of the process development are determine.
