中文摘要:
      分析了南海夏季风强度指数,与热带太平洋至印度洋0~400m海水海温距平场的相关关系,发现南海夏季风在120m层的信号最强,并且与ENSO循环有关。根据相关场反映的信息对季风强度与海温场分类,针对其中4种情况对120m层海温距平和850hPa U分量进行合成分析,发现热带海温异常影响南海夏季风强度,季风强弱反过来改变海温分布。最后给出了对季风和ENSO预报有指示意义的海温及风场分布。
英文摘要:
      Based on the correlative analysis between SCS(South China Sea) summer monsoon intensity index and sea temperature anomalous field in 0-400 m deep in tropical Pacific and India Oceans, the strongest signal of SCS summer monsoon is embodied in the level of 120 m, which has related with EN SO peried. Monsoon intensity and sea temperature are classified based on the information of correlation field. Composite analysis is done about 120 m temperature anomalous field and 850 hPa U component. It is found that tropical sea temperature anomaly affects SCS summer monsoon intensity, whereas monsoon intensity changes the distribution of sea temperature. At the end of the paper, sea temperature field and wind field are given which has the indicative meaning to monsoon and ENSO prediction.
