通过对湖北省几个典型伏旱年的同期环流特征的分析，揭示了与湖北严重伏旱灾害密切联系的几种大气环流系统，并进行了分型。指出造成严重伏旱的主要天气系统有西太平洋副热带高压、西风带环流和西太平洋台风，并根据伏旱期大气环流的不同型式，将造成湖北伏旱的环流特征主要归结为两类，一是副高势力强盛，西伸强烈，稳定控制长江中下游地区；中高纬度纬向环流占优势；台风活动较少。另一类是副高压势力较弱，主体位于太平洋海面上空；西北太平洋多台风活动，但不易登陆北移。
Through the analysis of the circulation characteristics of several typical summer months in Hubei Province, several types of atmospheric circulation systems closely related to the severe drought disaster in Hubei were revealed and classified. It is pointed out that the main weather systems causing serious drought are the western Pacific subtropical high, the westerly circulation and the western Pacific typhoon. According to different types of atmospheric circulation during the drought period, the circulation characteristics that cause the drought in Hubei can be mainly divided into two types. One is the subtropical high Strong, strong westward expansion, stable control of the middle and lower reaches of the Yangtze River; zonal circulation prevails in the middle and high latitudes; typhoon activity is less. The other is the subtropical pressure weaker forces, located in the Pacific Ocean over the sea; more typhoons in the northwest Pacific, but not easy to land north.
