摘要
概述了近40年来中国地区低空急流的研究成果,重点就我国低空急流的结构特征、可能机制及其对强对流天气的影响等进行了分析和总结,包括对低空急流按所在高度和风向两种方式进行分类、低空急流的空间分布和形成原因等。最后指出了目前研究的局限性及有待于进一步研究的问题,在我国针对低空急流本身结构特征的研究相对较少,应加强这方面的研究。
The advancements in the researches on LLJ （Low-Level Jet） in China in recent 40 years are reviewed with emphases on the structure characteristics and possible mechanisms of LLJ and the relationship between LLJ and severe convective weather, which include the classification of LLJ in two different ways, the spatial distribution, and the formation causes. However, the observation time for collecting radiosonde data and the occurrence time for LLJ do not match. Moreover, the special observation of LLJ has not been widely applied because of its high cost. Therefore, due to the difficulty of LLJ observation and the lack of specialized researches in China, the further study will be needed, especially in the structure characteristics of LLJ itself.
