| 摘 要： | 利用1967—2008年青藏高原68个台站逐日降水资料,按照《气象规范》对不同等级降水的定义,对青藏高原汛期（5—9月）不同强度的降水日数进行分析。结果表明：1967—2008年青藏高原汛期总降水日数及各强度降水日数均呈现出由东南向西北递减的空间分布特征,降水总日数和小雨日数以减少趋势为主,最显著的区域位于青藏高原东北...

| Abstract: | Based on the daily precipitation data in 68 weather stations from 1967 to 2008 over the Tibetan Plateau and the definition of precipitation of different intensity from the meteorological criterion,a number of precipitation days under the different intensity in the flood season from May to September were analyzed.The results indicate that the number of days of the total precipitation and the different intensity have the decreasing trends from the southeast to the northwest in the Tibetan Plateau.The number o... |
