天气和气候极端事件的变化及其与全球变暖的联系——纪念2002年世界气象日“减低对天气和气候极端事件的脆弱性”

Changes in Weather and Climate Extreme Events and Their Association with the Global Warming

20 0 2年 3月 2 3日世界气象日的主题是“减低天气和气候极端事件的脆弱性”。针对这个主题 ,作者对以下四方面问题作了阐述 :(1 )天气与气候极端事件以及脆弱性的定义 ;(2 )近百年来全球天气与气候极端事件的变化及其与全球气候变化的关系 ;(3 )未来天气与气候极端事件及其影响的预测 ;(4 )天气与气候极端事件的适应与减缓对策。由于篇幅有限 ,未介绍中国在这方面的研究。

The theme for World Meteorological Days (WMD),2002 is 'Reducing vulnerability to weather and climate extremes '. In the light of this theme, the following four problems are in general illustrated: (1) definitions of weather and climate extreme events; (2) changes in weather and climate extremes for the past 100 years on the global basis, and their association with global climate change ;(3) projection of global weather and climate extreme events for this century; and (4) adaptation and mitigation response strategy for reducing vulnerability to weather and climate extreme events. Due to space limitation, studies in this regard made by Chinese scientists have not included.
