Origin of thermohaline staircases

Witrynathe widespread occurrence of thermohaline staircases in diffusively stable regions of the World Ocean. Key words: convection, double diffusive convection 1.Introduction … WitrynaThe 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. [2] Six possible mechanisms are described below. [4] Collective instability mechanism [ edit]

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 … butter creek lodge packwood https://baileylicensing.com

Thermohaline staircase - Wikipedia

Witryna1 maj 1996 · The stratification of a water column in which a series of homogeneous layers alternate with high gradient interfaces is known as a stepped staircase or a stepwise thermohaline structure. 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). Witryna1 sty 2006 · Prominent thermohaline staircases are evident in profiles of temperature and salinity at locations that appear to correlate with the presence of lateral property gradients and shear within the eddy, although such a connection is less than definitive due to the coarseness of horizontal sampling. ...
