  • By application of normalization of the SLP data from Hadley and NCEP/NCAR, the East Asian Summer Monsoon (EASM) index from 1850 to 2011 are obtained. EMD method is adopted to analyze the periodic characteristics and get the EASM index cycles on various time scales. With three times analyses, the 11-year cycle component is obvious and has the highest correlation with the original data. Both the sunspot activity and the EASM activity have the same cycle component of 11-year and 80-year, especially the 11-year cycle component is obvious. With comparison between 11-year cycle component of sunspot number and that of EASM index, both of the fluctuation amplitude changes are basically identical.
