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。
The relationship among East Asia summer monsoon, El Nio and low temperature in Songliao 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 Nio temperature 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 Ni[AKn~D]o temperature going up started in the first half a year the high temperature in Songliao Plain in summer would take pace in the same year and the temperature in Songliao Plian in summer would be lower in the next year but there was no cool injury. The oscillation OLR in typical El Nio year has been analysed too. The relationship among El Nio, oscillation of OLR, East Asia summer monsoon, winter monsoon and the low temperature in Songliao Plain North East China has also been studied.
