Asymmetry of the Intertropical Convergence Zone 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. The ITCZ would be expected to overlie the geographic equator according to symmetric solar radiation. However, the ITCZ is mostly perennial in the northern hemisphere and in the eastern Pacific and Atlantic Oceans. It was originally explained by the asymmetrical distribution of continents. However, the distribution of land and ocean is severely asymmetric in the Indian Ocean, yet the ITCZ moves back and forth there between the southern and northern hemispheres. Continents surround
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.
