| Abstract: | The precipitation data of 38 years from 1958 to 1995 from 24 stations areused to analyze the precipitation characteristics in June in Guanzhong and SouthernShaanxi. 12 stations are selected as data station. The precipitation index of June is calculated and drought characteristics are studied for the two regions. Upper air circulationat 500 hPa when drought occurred in early summer is analytically compared with the average situation of calendar year and prediction is made to early summer drought. |
