| Abstract: | The analysis of the causes and characteristics of the serious drought occurred between summer and autumn of 2000 in Yulin and Guigang shows that the prevailing zonal circulation in the middle and high Europe Asia latitude between surmmer and autumn obstruct the southwards flow of cold air to Guangxi, resulting in the reducing of precipitation on frontal surface In the mean time, the sub high pressure persists in a weak status and it locates a little bit eastwards and northwards, resulting in the eastwards deflecting of typhoon route, which means that it didn't directly influence the east south part of Guangxi, and reduced the precipitaion in this part of Guangxi |
