Lake seiche thermocline

WebbEven quite shallow lake water can develop a thermocline in the short term but where there is a moderately windy climate, the circulation caused by wind drift is sufficient to break this up. (The surface is blown down-wind in a seiche and a return current passes either near the bottom or just above the thermocline if that is present at a sufficient … Webb22 juni 2001 · Since solitons are likely to break at the sloping boundaries, leading to localized turbulent mixing and enhanced dissipation, the transfer of energy from an initial basin-scale seiche to shorter solitons has important implications for the lake ecology.

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.

Quesnel Lake has a seiche period of about 6 days, thus wind events must be at least ~1.5 days long to excite a bar-oclinic seiche response (Laval et al., 2008).
