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

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
