摘要
利用NCEP/NCAR 1 998年再分析资料和SST资料 ,研究了 1 998年南海季风爆发的特征及其机制。结果显示 ,南海及其附近地区夏季风爆发分为 3个阶段 ,并具有不同的特征 ,在南海季风爆发前 ,南海海温已提前突然增温达极高值 ,感热通量梯度在海陆之间的转换可能是引起东亚副热带季风和南海季风爆发的重要因子。
In the context of reanalysis NCEP/NCAR daily data and SST in 1998, the features and mechanisms of summer monsoon onset over the South China Sea (SCS) are investigated. Results show that SCS and its vicinity summer monsoon can be divided into three phrases with different characteristics. SST of SCS increases to its maximum suddenly before SCS summer monsoon onset. The conversion of sensible heat flux between sea and land may be an important factor that induces onsets of East Asia subtropical monsoon and SCS monsoon.
