| 摘 要： | 利用ＯＬＲ和ＴＢＢ资料，提出一个指标，确定了１９７５～１９９３年间南海夏季风爆发日期，发现与风向转变的日期比较一致。在此基础上，讨论了南海夏季风爆发的过程。随后，还讨论了南海夏季风爆发与海温异常、高原热状况和海陆温差变化的关系，发现它与４月份南海、东太平洋赤道以及３０～４０°ＮＳＳＴＡ有关，与海陆温差由冬季的冷陆暖海转变到热陆冷海有关。

| Abstract: | Employing OLR and TBB data,we presented an index and decided the date of summer monsoon onset over South China Sea(SCS) during the period from 1975-1993, which is consistent with the date ofrecurvature of wind.On the basis of this,we discussed the pro cesses of summer monsoon over SCS.Furthermore,the relationship between summer monsoo nonsetover SCS and sea temperature anomaly,thermal regime over Tibetan Plateau as wellas variation of temperature difference between land and sea was discussed.we found it relates to SSTA in SCS,equatorial east Pacific and region between 30-40°N in Apriland it relates to changing of temperature difference land and sea from status of cool land and warm sea into status of warm land and cool sea in winter. |
