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.
Tropical rainforest climate year. One day in an equatorial climate can be very similar to the next, while the change in temperature between day and night may be larger than the average change in temperature during the year. A tropical rainforest climate is usually found at latitudes within 15 degrees North and South of the equator, which are dominated by the Intertropical Convergence Zone. The climate is most commonly found in South America, Central Africa, Southeast Asia and Oceania. These rainforests are uniformly and monotonously wet throughout the year.
