摘要
对1951~1998 年初夏500 hPa 高度场作单点遥相关分析,并重点分析1991~1998 年我国初夏旱涝与遥相关型的关系。结果显示:除1992 年以外,初夏的大涝(1991、1996、1998 年)和大旱(1997 年)都与东亚太平洋型、黄河东亚型的异常有关,而1998 年东北地区的涝还与异常强的WA 型有关。
One point correlation analysis is undertaken for 500hPa geopotential height field in early summer for 1951~1998,with focus on the relationship between teleconnection patterns and China early summer rainfall in 1991~1998.Results show that exceptional flood in 1991,1996,1998 and severe drought in 1997 bear connection with the anomaly of the east Asia pacipic(EAP) pattern and the Huanghe river east Asia(HEA) pattern with the exception of 1992,and that the flood in 1998 over northeast China is also linked to the anomous powerful west Asia(WA) pattern.
