摘要
东亚高空急流是东亚夏季风系统的一个重要组成部分,对东亚地区的天气和气候有着重要影响。近十年来,对东亚高空的变异规律及其相关机理、急流对东亚气候的影响等方面做了大量的观测资料分析和数值模拟研究。本文从夏季东亚高空急流的变化特征及其与东亚气候的关联、东亚高空急流的变异机理以及当前的气候模式对东亚高空急流的模拟能力评估和未来预估等几个方面,对这些研究结果进行了综述。
The East Asian upper-tropospheric jet is an important component of the East Asian summer monsoon and severely affects weather and climate in East Asia. During the past decade, various observational and numerical studies were conducted on variability in this jet and its effects on the East Asian climate. This paper reviews these studies mainly from the aspects of the features of the East Asian upper-tropospheric jet variability, the relationship between the jet and the East Asian climate, the possible mechanisms for jet variability, the evaluation of current climate models＇ ability in simulating the jet, and projections of future changes in the jet.
