Abstract:
The time coefficient series of the first characteristic vector of May-September precipitation at twenty-five stations is regarded as the drought/flood index over the Changjiang River valley. The correlation between the index and SST of the North Pacific and 500hPa height in the Northern Hemisphere is analysed and seven, factors have been examined and the stability of the factors are selected. The drought/flood trend of the area is predicted by use of the multiple fuzzy regression analysis.
