高原积雪 meaning in Chinese

highland snows

The characteristics of precipitation anomalies in summer , previous and simultaneous ssta and preceding winter accumulated snow depth anomalies corresponding to positive and negative phases of 10 - yr mode and 25 - 30 - yr mode are discussed respectively . no matter for 10 - yr mode or for 25 - 30 - yr mode , reverse characteristics corresponding to positive phases and negative phases appear in the above fields . it proves that the decadal variation of sah have a good relation to the decadal variation of other key element of climate system and we can regard sah as a strong signal of the anomalies in the climate system
( 4 )夏季南亚高压东西振荡具有明显的年代际变化特征，本文分别讨论了对应于10年周期态的正位相年和负位相年及25 - 30年周期态的正位相年和负位相年时夏季我国降水距平、前期及同期海温距平及前冬青藏高原积雪距平的分布特征，发现无论是10年周期态还是25 - 30年周期态，对于夏季南亚高压东西振荡的正位相年和负位相年以上各要素场呈现为很好的反位相特征，说明夏季南亚高压的年代际变化与气候系统中其他要素的年代际变化具有很好的关联性，可将南亚高压看作气候系统中大气子系统异常的强信号，通过分析南亚高压的年代际异常可以更直接地研究和预测区域气候异常。
