Witryna18 sty 1999 · One such hypothesis, that staircases arise from thermohaline intrusions, is developed into a quantitative theory. It is shown that growing intrusions evolve toward … Witryna8 lip 2013 · Three-dimensional dynamics of thermohaline staircases are investigated using a series of basin-scale staircase-resolving numerical simulations. The computational domain and forcing fields are chosen to reflect the size and structure of the North Atlantic subtropical thermocline. Salt-finger transport is parameterized using the …

WitrynaIt is generally accepted that staircases in the ocean are produced by double-diffusive convection, broadly defined as a combination of processes driven by dissimilar … WitrynaThe term thermohaline staircase describes a series of mixed layers separated by thin high-gradient interfaces, commonly observed in vertical profiles of temperature and salinity. Staircases in the Arctic and Southern Oceans are typically diffusive, with warm salty water masses located below those that are relatively cold and fresh.
Witryna1 Introduction. This study contributes to the discussion of the origin of thermohaline staircases in high-latitude regions of the World Ocean. The term thermohaline … Witrynathermohaline staircases—a series of mixed layers sepa-rated by thin stratified interfaces. While the appearance ... (2013)]. Theories proposed to explain the origin of staircases include the collective instability mechanism (Stern 1969), which attributes layering to the interaction between waves and double diffusion, and the suggestion …
WitrynaThe origin of thermohaline staircases relies on double diffusive convection, and specifically on the fact that heated water diffuses more readily than salty water. … WitrynaThermohaline staircases form where the vertical gradients of temperature and salinity have the same sign. These conditions most commonly occur in the Arctic, where cool …
