WATER VAPOR CONTENT AND MEAN TRANSFER IN THE ATMOSPHERE OVER NORTHWEST CHINA

摘要

The interannual and intermonthly climatic features of the water vapor content (hereafter WVC)and its mean transfer in the atmosphere over Northwest China(hereafter NWC)are Calculated and analyzed by using the NCEP/CNAR global reanalysis grid data(2.5°×2.5°Lat/Lon) For 40 years(1958-1997). The results show that the WVCin the total air colum over NWC in Four seasons of the year is mainly concentrated on eastern and western NWC respectively.
