摘　　要：利用NCEP再分析资料分析了2004、2005年南海夏季风建立的大尺度环流特征.采用GRAPES对2a南海夏季风爆发过程进行了模拟.结果表明:GRAPES成功的模拟了南海夏季风建立期间南海地区低层东风转向和副高迅速东撤的过程,通过数值模拟,揭示了南海夏季风建立过程中存在着的中低纬相互作用.Using the NCEP reanalysis data, the characteristics of the onset of South China Sea summer monsoon in 2004 and 2005 are analyzed. The onset of summer monsoon is simulated by means of GRAPES （Globe/Regional Assimilation Predict Enhanced System）. The numerical experiment shows that GRAPES successfully reproduces the evolution of summer monsoon＇s onset, such as the rapid conversion of easterlies and the subtropical high withdrawing. Through simulation, the interaction of low-and middle-latitude has been revealed in the process of the onset of South China Sea summer monsoon.
