摘要: 对几十年来国内外对天气尺度梅雨锋研究结果进行了综述,众多研究成果表明梅雨锋具有多样性的特点。由于众多研究者对梅雨锋的定义存在很大的差异,因此在综合国内外不同观点的基础上,给出了梅雨锋的天气学定义,即:梅雨锋具有一条数千公里长的横贯东亚和西太平洋地区的雨带;梅雨雨带随季风的进退而进退,梅雨锋是季风气团和其他气团之间的锋面;梅雨锋区是位于夏季风北侧的相当位温强梯度带。

Abstract: The progress on synoptic scale Meiyu front is summarized after 1930 s. The existed studies show that the structure of the Meiyu front is very complicated, and has a multiformity feature. Based on previous studies, the synoptics' definition of Meiyu front is given as: there exists a narrow rain band of thousands of kilometers long across East Asia and northwestern Pacific; the rain band advances and retreats closely related with the Asia monsoon, and the frontal surface is between warm monsoon air mass and the others; and the Meiyu frontal area is a band with high gradient of θse.

Key words: Meiyu front, synoptic scale, multiformity, synoptics' definition
