Guangxi is located in the northern hemisphere low latitude, a subtropical monsoon climate zone, vulnerable to atmospheric circulation in the southern hemisphere. Analysis of the relationship between the atmospheric circulation in the southern hemisphere and drought and flood in Guangxi is one of the important tasks in the search for precursors of drought and flood. Based on a large number of correlation analysis and comparative analysis, this paper searches for some important information for forecasting drought and flood in flood season in Guangxi from the circulation changes in the southern hemisphere. 1 data precipitation amount of capital
