本文回顧近年來華南╱臺灣與長江梅雨鋒之研究，除探討梅雨降水在季節降水分佈之重要性外，亦探討梅雨鋒之氣候特徵與臺灣地區梅雨鋒降水。在梅雨鋒結構方面，除探討其特殊性外，亦探討伴隨之垂直次環流。最後探討梅雨鋒與對流之關係，及對流潛熱釋放在梅雨鋒生過程所扮演之角色。

　　　　　The recent research on the Meiyu front over sourthern China/Taiwan and the Yangtze River Valley was reviewed. The significance of the Meiyu rainfall in the seasonal distribution was illustrated. The climatological characteristics of the Meiyu front and the Meiyu frontal rainfall over Taiwan area were discussed. The uniqueness of the frontal structure and the associated secondary circulation were illustrated. Finally, the relation of the front and convection as well as the role of convective latent heating on the Meiyu frontogenesis was discussed.
