南极地区气温变化的一些特征

本文利用南极地区考察站的气温资料,对该地区气温的季节变化和年变化进行统计分析。结果表明,南极地区气温的季节变化有明显的区域性和两季特点,东南极大陆是冷中心,在南极地区气温变化中起重要作用,极点气温的年际变率不大,南极地区气温场中存在ENSO事件的信号。

THE TEMPERATURE VARIATIONS OF THE ANTARCTIC

Using temperature data of the Antarctic stations, the seasonal variation and the annual variation of the Antarctic temperature have been analysed statistically. The results shows that the variation has obvious regional and two seasonal features. The cold center is in the eastern Antarctica which plays an important role in the temperature variation in the Antarctic. The temperature annual variation at South Pole in smaller than other regions., and some ENSO signals in the Antarctic temperature change have been found.
