摘要
根据近４０年水文气象资料和每日历史天气圈，分析了西藏地区降水及其时空分布的基本特点，描述和讨论了藏南降水的天气尺度系统和干旱成因。作者还根据近百年历史水旱资料，探索了藏南气候变化规律，并对ＥＬ＇Ｎｉｎｏ事件与藏南气候异常的关系作了一些解释。
Based on the hydro-meteorological data for about 40 years and daily weathermaps, the elementary feattures of precipitation and its distrbution in the Tibetan region areanalysed. And the synoptic-scale systems resulted in precipitation and causes of drought formation are also described and discussed in this paper. By using historical data of droughtflood for nearly one hundred years, the authors studied the regularity of variation of climate inthe south of Tibetan Plateau and explained anomaly of climatte in these regions in comparisonwith EL'Nino events.
