摘要: 气候的变动性包括长时期的气候变化趋势和短时间的气候波动。七十年代由于出现世界性的气候异常及其对世界粮食生产带来的巨大影响,使得这种短时期的气候波动(主要是温度和降水)成为人们普遍关心的重大问题。

Abstract: Records of 432 weather stations in China fnom 1951 to 1980 are taken in this paper to study the characteristics of spatial and temporal distribution of temperature variabi-lity. The conclusions can be drawn as follows:1. Annual temperature variability is relatively small at lew latitude and increases with latitude.2. The position of high temperature variability center is almost identical with the position of climatic fronts and main patlies of cyclone and anticyclone activities. ’3. High center of temperature variability over the Xizang Plateau can be related to the trough activities in westerlies. There is more unanomialous corresponding rela-tion-ship between high temperature variability center of the southern Xizang mounta-ins and seasonal activity of subtropical jet.4. The maximum of temperature variability is evident in winter and the minimum in summer. Interannual temperature variation ;s very severe in winter at high latitu-de.
