Generation of upwelling near the Pacific Coast of Mexico

Abstract

In a series of numerical experiments, we simulate the process of generation of coastal upwelling induced by the winds of various directions in the central part of the Pacific Coast of Mexico (18N, 103-107W). The numerical nonlinear multilevel model [see .N. Mikhailova, I. M. Semenyuk, and N. B. Shapiro, "Modeling of the variability of hydrophysical fields in the Tropical Atlantic," Izv. Akad. Nauk SSSR, Fiz. Atmosf. Okean., 27, No. 10, 1139-1148 (1991)] is adapted to the region of investigations with 9-km space resolution by specifying the conditions of flow through the open lateral boundaries. The results of numerical experiments demonstrate that the NW, N, NE, and E winds are especially favorable for the generation of intense upwelling. 2005 Springer Science+Business Media, Inc.
