Thermal Stratification of Lakes Many lakes, particularly deep ones, stratify during at least part of the year. Abstract . regards changes of thermal stratification Lake Victoria would appear to be the best known example, following observations in 1927-8 by Graham (1929) and Worthington (1930) and in 1952-4 by Ii’ish (1957). Thermal stratification is simply the development of persistent layers, characterized by dense, cold water called a hypolimnion near the bottom of the lake and the warmer, less dense epilimnion near the surface.

Lake stratification is the separation of lakes into three layers:. Thermal stratification • In the still waters of a lake, mixing between the surface and deeper layers may not occur except occasionally. Physics, Solar Such thermal stratification occurs because of the large differences in density (weight) between warm and cold waters. We conclude that it is possible to simulate the development of thermal stratification under laboratory conditions. As a result, thermal stratification can be established during the warm season if a lake is sufficiently deep. The warming of the surface of the water by the sun causes water density variations and initiates thermal stratification. Hypolimnion: the bottom layer.
