摘要利用SMS-1地球同步卫星的优质资料，确定了GATE在东大西洋和西非三个阶段发生的扰动线。这些扰动线大多在陆地上产生并衰减。创世纪主要发生在下午的陆地上，而在清晨的水面上。它们发展到与西南季风相关的云系统的北部，在那里，潮湿层较浅，上部的干燥空气有利于通过降水蒸发产生下沉气流，而形成在很大程度上取决于与行波相关的日晒和低层辐合。
Abstract The disturbance lines which occurred during the three phases of GATE over the eastern Atlantic Ocean and West Africa have been identified utilizing the excellent data from the SMS-1 geostationary satellite. The majority of these disturbance lines generated and decayed over land. Genesis occurred predominantly in the afternoon over land and in the early morning over water. They develop to the north of the cloud systems associated with the southwest monsoon, where the moist layer is shallow and the overriding dry air favors the production of downdrafts by the evaporation of precipitation and genesis is to a large extent dependent on insolation and low-level convergence associated with traveling waves.
