Abstract:
The daily meteorological data at 37 stations in Jiangsu Province, the NCEP/NCAR reanalysis data of monthly mean geopotential height and wind fields, and the data of the North Pacific sea surface temperature (SST) from 1980 to 2009 are analyzed by methods of composite and teleconnection. The characteristics of atmospheric circulation and North Pacific SST were studied when comfort index of human body (CIHB) was anomalous in winter and summer. The results indicated that: （1) the cold air force in winter is weaker when the CIHB is higher than that when the CIHB is lower. Because East Asian trough is shallower, winter monsoon is weaker especially the north wind and downdraft are also weaker at the stage of higher CIHB than lower CIHB. In summer, subtropical high was found to be westward and strengtherning and South Asia high lies easterly and northerly and strengtherns in the higher CIHB stage, including the stronger summer monsoon and weaker vertical convection. （2) In winter, SST in the Midwest Pacific at the stage of higher CIHB is warmer than the lower CIHB, particularly in Kuroshio in China eastern offshore. No matter the leading or contemporaneous correlation, the correlation between the West Pacific SST and the CIHB in winter is positive mainly, especially in Kuroshio.
