Trade winds Fontaine Maury collected enough information to create wind and current charts for the world's oceans. As part of the Hadley cell, surface air flows toward the equator while the flow aloft is towards the poles. A low-pressure area of calm, light variable winds near the equator is known as the doldrums, near-equatorial trough, intertropical front, or the Intertropical Convergence Zone. When located within a monsoon region, this zone of low pressure and wind convergence is also known as the monsoon trough. Around 30° in both hemispheres, air begins to descend toward the surface in subtropical high-pressure belts known as subtropical
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
