Abstract: Based on the mean monthly wind field reanalysis data from the NCEP/NCAR and temperature data at 160 weather stations provided by the national climate center from 1951 to 2010, the mass stream function scheme and circulation center value were used to analyze Hadley circulation intensity changes and their relations with temperature in the eastern China. The results show that the mean meridian circulation can well be described by the mass stream function, and circulation center value can represent its intensity vividly. The winter Hadley intensity in the northern hemisphere has a linear increasing trend in the past 60 years, while the summer Hadley intensity in the southern hemisphere has a turning point of inter-decadal change from decreasing trend to increasing trend in the early of 1980s. The inter-decadal change of temperature in the eastern China could be explained well by changes of Hadley circulation intensity. Both relationships are positive, while they are different with the change of seasons in the significant correlation areas.
