气候变化检测与诊断技术的若干新进展

Latest advances of climate change detecting technologies

近年来,全球气候变暖及其对世界经济的影响已经引起了社会各界的关注和重视,判断当前全球的温度变化趋势,已经成为研究气候变化的一个至关重要的问题。进一步发展新的气候变化检测技术以适应全球增暖的新特征则显得尤为重要。因此,结合(1)气候突变和转折检测技术、(2)观测数据信息的分离和提取、(3)气候系统内在复杂性、(4)气候系统动力学结构特征的识别、(5)极端气候事件定义及其检测等方面的气候变化检测技术研究,分别介绍了中国近期气候变化检测技术的研究进展及部分研究成果,主要侧重于新检测技术和方法的介绍。最后,就当前气候变化检测技术方面的一些焦点和难点问题做了简单的讨论。

Global warming and its influences on world society and economic had caused the attention of all the people in different countries. Predicting the future trend of global temperature change had become a extremely serious problem climate research. It is also rather important to develop new climate detecting technologies to adapt the new characteristics of global warming. So, based on five aspects of climate detecting technologies research： （1） abrupt climate change detecting, （2） separating the useful information of observed data, （3） complexity of climate system, （4） discerning of the dynamical characteristics of climate system, （5） definition and detection of extreme events et al. , latest advances of these aspects and their research results are briefly introduced. At last, probable difficulties and key problems in climate change detecting technologies are discussed.
