Witryna1 kwi 2024 · This model was first introduced by Stern (1967), who delineated three separate scales of motion: small, to describe double-diffusive processes on centimeter to meter scales; medium, to describe the scales of interleaving (order tens of meters vertically and kilometer scales laterally); and large, to characterize the background … Witryna1 maj 2000 · Abstract Hypotheses concerning the origin of thermohaline staircases in salt fingering regions are reviewed and assessed. One such hypothesis, that staircases arise from thermohaline intrusions, is developed into a quantitative theory. It is shown that growing intrusions evolve toward staircases when the background density ratio …

Such structures have been found in several regions of the world's oceans (Tait and Howe, 1971; Jacobs et al., 1981; Schmitt et a,1987). dayton daily news obituaries view by locationThe origin of thermohaline staircases relies on double diffusive convection, and specifically on the fact that heated water diffuses more readily than salty water. However, there is still much debate on which specific mechanism of layering plays a role. Six possible mechanisms are described below. This mechanism, involving collective instability, relies on the idea that after a period of active int… dayton daily news obituaries march 2019WitrynaThermohaline staircases form where the vertical gradients of temperature and salinity have the same sign.
