Effects of Surface Heating on Coastal Upwelling Intensity

Numerical experiments were conducted to evaluate the effects of surface heating on coastal upwelling intensity. Offshore transport, isopycnal slope, and sea temperature (SST) difference between offshore regions, which represent intensity, estimated. Surface decreases Ekman transport but increases pumping by changing air-sea stability conditions. However, does not change significantly with heating. Our experimental results revealed that increase in slope SST difference. Both are closely related boundary layer (SBL). Strong thins surface-mixed layer, vertical eddy viscosity. The decreased viscosity SBL enhances its velocity. weakens because thin SBL, while becomes stronger enhanced velocity despite same transport. present study may be relevant systems as under future global warming.
