WebAs warm surface waters are pushed away by the wind, deep cold waters near shore upwell to the surface (see Big Sable Point bathymetry). South or southwest (or even straight west winds) cause warm water to ‘pile up’ in the bay. Under these conditions, warm waters will be found as deep as 150 feet or more (typical depth of warm water is 60-70 feet). WebAug 8, 2011 · And second, cold water from the deep ocean comes up to the surface through a process called upwelling. From March through September, wind blows southward along the coast. This wind, combined with the rotation of the earth, creates surface currents that move water from the coast out into the ocean.

WebNorth Atlantic Ocean, where cold water that surrounds the ice sinksthe , and starts to flow around the world. A current is created as warm water rushes to the surface to replace the sinking cold water. The cold, dense water moves southward in between the continents toward South America and Africa—and as it passes the equator, the water warms. WebAs the surface water moves west, it is replaced by cold, nutrient-rich deep water through upwelling (Figure 9.6.1). The coastal upwelling leads to a shallow thermocline in the eastern Pacific. In terms of atmospheric conditions, the trade winds are part of a convection cell called the Walker Cell. There is low pressure rockbeare facebook
