WebDownwelling leads to reduced productivity, as it extends the depth of the nutrient-limited layer. Upwelling occurs where surface currents are diverging, or moving away from each … WebDownwelling short-wave radiation at the surface has a component due to the direct solar beam, and a diffuse component scattered from atmospheric constituents and reflected from clouds. Upwelling short-wave radiation comes from reflection at the surface.

WebA coastal downwelling is the opposite of a coastal upwelling. Warm surface water can be blown towards the shore by Ekman transport. This warm water mass pushes cold water down and away from the shore. Another kind of downwelling occurs when there is a buildup of the water in the center of a hurricane or in other low-pressure centers. Webnet gain or loss of radiation = downwelling solar + downwelling IR - upwelling IR This simple equation can be used to get a rough idea of the temperature trend of the surface. For example, using the graph above, look at the values of the three components at 1800Z.
