A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth. In the ocean, the thermocline divides the upper mixed ...
Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.
Cryostratified lakes exhibit inverse stratification near the ice surface and have depth-averaged temperatures near 4 °C, while cryomictic lakes have no under-ice thermocline and have depth-averaged winter temperatures closer to 0 °C. [19]
The bottom layer is the hypolimnion, which tends to have the coldest water because its depth restricts sunlight from reaching it. [17] In temperate lakes, fall-season cooling of surface water results in turnover of the water column, where the thermocline is disrupted, and the lake temperature profile becomes more uniform.
A thermocline is established, and the cycle repeats. [1] [2] Seasonal stratification in temperate lakes. Wind ... as well as lake or pool depth and productivity.
'lake'. [2] It is the layer that lies below the thermocline. Typically the hypolimnion is the coldest layer of a lake in summer, and the warmest layer during winter. [1] In deep, temperate lakes, the bottom-most waters of the hypolimnion are typically close to 4 °C throughout the year. The hypolimnion may be much warmer in lakes at warmer ...
Lake Erie laps away in northern Ohio and is the 11th largest lake in the world. Here are some facts about the Great Lakes. Lake Erie. Average depth: 62 feet. Maximum depth: 210 feet. Size: 9,910 ...
It draws water from Lake Ontario through tubes extending 5 kilometres (3.1 mi) into the lake, reaching to a depth of 83 metres (272 ft) where the water is maintained at a constant 4 °C, its temperature protected by a layer of water above it, called a thermocline. The deep lake water cooling system is part of an integrated district cooling ...
