IMPACTS OF ANTARCTIC OSCILLATION ON SUMMER MOISTURE TRANSPORT AND PRECIPITATION IN EASTERN CHINA
Using NCEP/NCAR reanalysis data and monthly precipitation over 160 conventional stations in China,analyses of moisture transport characteristics and corresponding precipitation variation in the east part of China in summer are made, and studies are carried out on possible influence on moisture transport and precipitation in summer by the variation of Antarctic Oscillation (AAO). The results show that the abnormal variation of the AAO affected the summer precipitation in China significantly. The variation of AAO can cause the variation ofintension and location of Northwestern Pacific High, which in turn cause the variation of summer monsoon rainfall in the eastern China.
