Lake seiche thermocline

Webb14 aug. 2003 · During the cool windy season (May to September), strong southerly winds tilt the thermocline, causing upwelling of deeper nutrient-rich waters at the south end of the lake and initiating seiche ... 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, … Visa mer Most of the heat energy of the sunlight that strikes the Earth is absorbed in the first few centimeters at the ocean's surface, which heats during the day and cools at night as heat energy is lost to space by radiation. Visa mer Thermoclines can also be observed in lakes. In colder climates, this leads to a phenomenon called stratification. During the summer, warm water, which is less dense, will sit on top of colder, denser, deeper water with a thermocline separating them. … Visa mer • Bathythermograph – Device to detect water temperature and pressure • Thermohaline circulation – Part of large-scale ocean circulation • Artificial upwelling – Replacement by deep water moving upwards of surface water driven offshore by wind Visa mer The thermocline in the ocean can vary in depth and strength seasonally. This is particularly noticeable in mid-latitudes with a thicker mixed layer in the winter and thinner mixed layer in summer. The cooler winter temperatures cause the thermocline to drop to further … Visa mer Thermocline - A gradiant based on distinct temperature differences within a body of similar matter. ie.

Basically it piles up the water above the … Seiches have been observed on both lakes and seas. The key requirement is that the body of water be partially constrained to allow formation of standing waves. Regularity of geometry is not required; even harbours with exceedingly irregular shapes are routinely observed to oscillate with very stable frequencies. Low rhythmic seiches are almost always present on larger lakes. They are us…
