Dynamic and Thermodynamic Structures of Convective Storms in Northern Taiwan Determined from Doppler Data

山洪灾害是全球性的重大气象灾害。理解这种现象是一个具有挑战性的问题，因为有必要了解运动尺度上的复杂动态和微物理过程，这些运动尺度比传统气象网络通常测量的要小。这种运动尺度被气象学家称为中尺度。​1987年春，台湾地区中尺度试验（Taiwan Area Mesoscale Experiment）进行了一项主要的野外项目，以研究引起山洪暴发的系统。该项目由美国国家科学委员会共同发起，美国国家科学基金会和美国国家海洋和大气管理局参与。首席研究员参加了野外考察，对资料进行了初步研究，揭示了副热带中尺度对流系统的结构及其与中纬度系统的异同。这种比较在过去没有受到太多关注。首席研究员将继续这项研究，特别注意比较两个具有非常不同降水特征的对流系统的动力和热力学特征。

Flash floods are major meteorological disasters which occur around the globe. Understanding of this phenomena is a challenging problem because it is necessary to understand both complex dynamic and microphysical processes at scales of motion that are smaller than typically measured by conventional weather networks. This scale of motion is termed mesoscale by meteorologists. The National Science Council of Taiwan has established a Multiple Hazards Mitigation Project whose meteorological component is focussed on improving flash flood predictions. A major field project to study the systems that cause flash floods, entitled the Taiwan Area Mesoscale Experiment, was held in the Spring of 1987. The project was cosponsored by the National Science Council with participation of the National Science Foundation and the National Oceanic and Atmospheric Administration of the United States. The Principal Investigator participated in the field expedition and his preliminary research on the data has revealed the structure of subtropical mesoscale convective systems and the differences and similarities with mid-latitude systems. Such comparisons have not received much attention in the past. The Principal Investigator will continue this research with special attention to comparing the dynamic and thermodynamic characteristics of two convective systems that possessed very different precipitation characteristics.
