厄尔尼诺现象与我国温度

本文分析了厄尔尼诺现象和反厄尔尼诺现象与中国温度的关系。结果表明,在厄尔尼诺当年的春夏季我国温度容易偏冷,冷月出现的频率明显高于气候概率;在厄尔尼诺当年的秋冬季至次年春季我国温度偏暖的可能性大,暖月出现的频率明显高于气候概率。反厄尔尼诺年的情况则正好相反,即当年春夏季我国温度容易偏暖,当年秋冬季至次年春季容易偏冷。进一步分析表明,厄尔尼诺暖水期,我国温度的分布型与黑潮区海温当年春夏季偏低、当年秋冬季至次年春季偏高的季节变化密切相关。

El-Nino and temperature variation in China

The relationship between El-Nino and the temperature in China is analysed in the paper. The results indicate that the temperature is lower in the spring and summer but higher in the autumn, winter and the following spring than normal during the El-Nino period. The change is caused by seasonal change of the sea surface temperature that is lower in the summer half year and is higher in the winter half year during the period in Kuro-shio current region. Temperature distribution is reverse during La-Nino period.
