| 摘 要： | 本文对近期关于青藏高原地区气候变化的研究进行了回顾。结果表明,在过去的几十年间,青藏高原地区的气候发生了明显的变化。主要表现为：1）温度呈上升趋势;降水和积雪呈增加趋势,多年冻土呈退化状态;温度和降水的变化不仅有季节性的差异,还存在区域性的差异。2）区域气候模式RegCM对青藏高原地区温度和降水有一定的模拟能力,但存在系统性的误差。文中还对在青藏高原气候变化方面的研究不足进行了讨论。

| Abstract: | The paper reviewed the recent progress in the climate change over Tibetan Plateau.The results showed that in the past several decades,the Tibetan Plateau climate had significant change,mainly as follows: 1)the temperature increased,the precipitation and snow depth also increased,and the frozen ground was degradation;temperature and precipitation change has seasonal differences and regional differences.2)regional climate model(RegCM3) was used over Tibet Plateau for the simulation analysis,the simulation results had systematic errors.The article also discussed the deficiencies of climate change over Tibet Plateau. |
