| 摘 要： | 分析了１９５１～１９９５年东亚夏季风、ＥｌＮｉｎｏ与中国松辽平原的代表站长春站夏季农作物生长期（５～９月）气温关系，结果表明：２０世纪５０～７０年代，东亚夏季风偏弱，ＥｌＮｉｎｏ增温始于上半年，长春夏季多气温偏低或有低温冷害发生；１９８０～１９９５年，东亚夏季风偏强，即使ＥｌＮｉｎｏ增温始于上半年，当年长春夏季气温多为稍高到偏高，次年夏季气温稍低，但不致出现偏低和低温冷害。初步分析了典型ＥｌＮｉｎｏ年ＯＬＲ季内振荡特征，研究了ＥｌＮｉｎｏ，ＯＬＲ季内振荡、东亚夏季和冬季风对松辽平原夏季低温影响的某些成因。

| Abstract: | The relationship among East Asia summer monsoon, El Niño and low temperature in Song liao Plain North East China from May to September in 1951-1995 are analysed. In 1950-1970's when East Asia summer monsoon was weak and El Niño temperat ure going up started in the first half a year the low temperature or cool injury in Songliao Plain would take place. During 1980-1995 when East Asia summer monsoon was strong even El Niño temperat uregoing up started in the first half a year the high temperature in Song liao Plain in summer would takepace in the same year and the temperature in Song liao Plian in summer would be lower in the nextyear but there was no cool injury. The oscill ation OLR in typical El Niño year has been analy sed too. The relationship among El Niño, oscill ation of OLR, East Asia summer monsoon, winter monsoon and the low temperature in Song liao Plain North East China has also been studied. |
