These cold patches are what remains of the subsurface "engine" of the La Nina, now starting to turn off slowly as warmer waters move in. a. Since 86% of global evaporation and 78% of global precipitation occur over the ocean, ocean surface salinity is the key variable for understanding how fresh water input and output affects ocean dynamics. d. troponin All this heating and cooling and melting and thawing creates a layered ocean: warmer fresher water on top, cold salty water at the bottom. Comparison of TOPEX/Poseidon and Jason Altimetry with ARAMIS In Situ All rights reserved. These two components act simultaneously to drive the MOC, the movement of seawater across basins and depths. The gazell remains are ingested by hyenas and vultures. c. increased mosquito borne disease in tropical areas While this model does not depict the ocean circulation patterns that results from atmospheric wind and density differences in water masses, it summarizes the key concepts involved in explaining this process. Thermohaline circulation occurs because winds move warm surface waters from the equator towards the poles, where the water cools and increases in density. The results presented above can be concisely summarized using a regime diagram to illustrate circulation direction as a function of three variables: mean temperature, equator-pole temperature gradient, and equator-pole salinity gradient ( Fig. e.
