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.
Geography of the British Virgin Islands sea and exclusive a fishing zone. It has a tropical, humid climate, with temperatures moderated by trade winds. Its terrain consists of coral islands, and is relatively flat. It has volcanic islands and is steep and hilly. Its lowest point is the Caribbean Sea and its highest point is Mount Sage at above sea level. Its natural resources are negligible. In terms of land use, it is 20% arable land, 6.67% permanent crops and 73.33% other as of a 2005 figure. Its natural hazards consist of hurricanes and tropical storms from July to October. There is limited natural fresh water
