“六月突变”前后大气环流对太平洋海温异常响应的数值试验

NUMERICAL STUDY ON RESPONSE OF ATMOSPHERIC CIRCULATIONS TO PACIFIC SSTA AROUND THEIR “JUNE ABRUPT CHANGE”

采用中国科学院大气物理研究所大气环流模式（ＩＡＰＧＣＭ）的持续积分方案，模拟了４、５、６三个月大气环流对正常、异常海温强迫的响应。结果表明，持续积分结果较通常积分结果约提前一个月，其余特点保持不变。因此。

Response of April June atmospheric circulations to normal and anomalous SST forcing has been investigated in terms of the perpetual integration of the General Circulation Model developed by Institute of Atmospheric Physics, Academia Sinica (IAP GCM). Evidence suggests that the perpetual run will offer a forecast one month earlier as compared to usual integration schemes without losing accuracy, thus presenting a possible approach to monthly prediction based on the GCM.
