Asymmetry of the Intertropical Convergence Zone it is the equatorial upwelling that prevents the ITCZ being created at the equator. To explain this simply, upwelling brings cold water to the surface, which will cool the above atmosphere and make it stable because of relative high air density due to low temperature. Thus, this area of the equator is different compared to the strong vertical convection and abundant precipitation of the ITCZ. As a result, the SST is latitudinally asymmetric. Asymmetry of the Intertropical Convergence Zone There are a number of explanations of the asymmetry of the Intertropical Convergence Zone (ITCZ), known by sailors as The Doldrums.
Colón Free Trade Zone Colón Free Trade Zone The Colón Free Trade Zone is a large entity near the Atlantic entrance to the Panama Canal, located in Panama dedicated to re-exporting a wide variety of merchandise to Latin America and the Caribbean. It is a free port. The Colón Free Trade Zone is the largest free port in the Americas, and second largest in the world. It started operations in 1948 and occupies about . It is divided in two large areas: one located in Colón, segregated from the city by a wall, and the other relatively new, in the harbor area, which is
