| Abstract: | In this paper, features of mesoscale and microscale structure of the " May 21" heavy rain in North Fujian in 1988 are analyzed with large amount of intensive observation data. These analyses show: (1) the interaction, generation and dissipation, and combination of systems (cloud cluster) on different scales and with different physical features (2) the importance of the wuyi mountain range complex in the above-mentioned processes, (3) the characteristics of continual heavy rain caused by the activity of mesoscale and microscale systems in low latitude mountain areas, where the weather changes frequently in certain environmental streamline field. |
