Abstract

The Colombian Pacific Basin is characterized by the influence of the North and South Trade Winds, which generate the denominated Intertropical Convergence Zone. This presented dynamics in the wind vectors on the region, is associated with a strong convective activity, explaining the high pluviosity indexes over that region. Also, it is considered of great importance to identify the behaviour of the surface winds in the Gulf of Panama, keeping in mind that in this region atmospheric processes of important magnitude are made, as it is it the Panama wind jet. The present work quantifies the horizontal winds field of the Colombian Pacific marine and coastal zone by means of in situ and satellite data, with a 25 Km of spatial scale. In addition, it is obtained the annual, semiannual and multianual behavior of the zonal and southern superficial horizontal wind over the studied areas. It is developed a correlation analysis between the in situ and satellite data in march 2006. The established climatology indicates that Colombian Pacific Basin (CPB) and the Gulf of Panama show a semiannual seasonal behavior. During the first semester the North Trade winds predominate, with average intensities between 5 and 7m.s-1, during this period the Panama wind jet is detected on the CPB, regulating the CPB oceanographic conditions. In the second semester (July-December), the ITCZ and the Panama Wind jet remain absented on the CPB, being presented prevalence of South-west Trade winds of the Chocó wind jet on the study areas. Finally it is present the relation between the annual and semiannual magnitudes of the CPB and the Chocó wind jet.
