Numerical model of the circulation induced by the wind at Bahia de Los Angeles, B.C., Mexico

Abstract

The circulation induced by the M2 component of the tide and wind at Bahía de los Angeles was predicted. The tide amplitude and the phase are practically the same at the bay, the tide currents values are 3 cm/s and the tide residuals 0.5 cm/s. Otherwise, the induced currents by the wind reach until 25 cm/s at the intensification areas. The coast configuration and the bathymetry dominate the main characteristics of the circulation. There is a strong interchange with the exterior to any dominant direction of the wind, and a persistent gyre at the inlet of La Gringa and at the middle of the bay. The most intenses flux zones are the southern channel and the coastal zone to the South of La Gringa inlet.
