| Abstract: | The statistical relationship between El Nino and flooding in Dongting Lake region of Hunan was analysed.The results showed that flooding occurred in the year after El Nino year with great probability in above mentioned region.The relationship between subtropical high of west Pacific and flooding of this region in 1998 was studied.It was demonstrated that abnormality of the former is a major cause of formation of this flooding.Then mechanism between El Nino and subtropical high of west Pacific was discussed.It was pointed out that the former can affect the change of the latter.The influence of adjustment of atmosphere general circulation on strong precipitation of Dongting Lake region in summer of 1998 was also studied. |
