Abstract
A surface wind (seabreeze), thermally generated by differential sea surface temperature, is introduced to Gil-Clarke's model (1974) through wind stress for investigating the effects of seabreeze on coastal upwelling. A coupled air-sea system is treated as an eigenvalue problem. The solutions show that the thermally forced local winds break down the coast Kelvin wave into three parts; small-scale (L>100 km) growing and stationary models, mesocale (100 km 200 km) coastl Kelvin modes. The consistency of the length scale between the most growing mode predicted by this model and the observed cold/warm alteration pattern of surface water near the Peruvian Coast (around 15 *S) implies that seabreeze may play some role in coastal upwelling.
