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
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
