Relevant Analysis Between Hadley Circulation Intensity and Temperature in Middle and Eastern China
Abstract：Based on the NCEP/NCAR reanalysis monthly wind data and 160 meteorological stations temperature data provided by National Climate Center, the mass stream function scheme and circulation center value were used to analyze Hadley circulation intensity changes from 1951 to 2010 and their relations with temperature in middle and eastern China. The results are as follows. 1） Mean meridional circulation can well be described by mass stream function, and circulation center value can represent its in- tensity vividly. 2） During the past 60 years, the intensity of boreal Hadley cell in winter tends to stronger, while the southern Hadley cell in summer shows interdecadal change from weakening trend to significant increasing trend in 1980s. 3） The interdecadal change of temperature in middle and eastern China could be explained well by changes of Hadley circulation intensity, and there exist some positive correlation between them. High related areas are changed with the season.
