Description :
Based on the drought/flood grades of 90 meterological stations over eastern China and summer average sea-level pressure (SLP) during 1850–2008 and BPCCA statistical methods, the coupling relationship between the drought/flood grades and the East Asian summer SLP is analyzed. The results show that there are 4 typical drought and flood spatial distribution patterns in eastern China, i.e. the distribution of drought/flood in southern China is contrary to the other regions. It is suggested that there is a relationship between solar activity and the East Asian summer monsoon and the interdecadal variation of drought/flood distributions.
