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
Inter-Collegiate Sailing Association World War. Harvard and Yale held a sailing event in 1911, but this was a long-distance 'cruise' rather than a fleet or team race, and only one Yale yacht attended the event! What is now the US Inter-Collegiate Sailing Association (ICSA) was established in 1930 as the ICYRA, although inter-collegiate fleet racing had started in Eight-Metres in 1928 for what is now the McMillan Cup. The first inter-collegiate dinghy fleet event, the Boston Dinghy Club Challenge Cup, took place with 34 entrants in 1930 (in parallel with the founding of the ICYA), and there was a dinghy event between Princeton
