【摘要】 本文利用“5.21”福建闽北特大暴雨过程中获得大量加密资料,较深入地分析了暴雨过程中、小尺度特征.给出不同尺度、不同物理特性的中小尺度系统(云团)相互作用,生消、发展、组合过程,以及武夷山脉的复杂地形在该过程中所起的重要作用.显示出在一定环境流场下,由中小尺度天气系统活动导致出现的天气变化密集的低纬山区形成持续性特大暴雨的重要特色.更多还原

【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.更多还原
