The rapid development and intensification of winter cyclones in coastal regions presents a major weather forecasting problem. Along the East Coast of the United States, the development of cyclonic storms and frontal systems often occurs along the coastal region of the Carolinas. These weather systems may lead to severe weather in the heavily populated Northeast Corridor in the form of freezing rain, heavy snowfall, blizzards and extensive coastal erosion. A complex interaction of cold continental air, warm ocean currents, traveling atmospheric disturbances and local geography all appear to contribute to the rapid development of these systems; however, the processes are not well understood and the phenomena are often poorly forecast. In January-March 1986 a cooperative research project to study winter storms in this region was held by a consortium of universities and Federal agencies. Entitled GALE (Genesis of Atlantic Lows Experiment), the project was designed to provide detailed information on the role of air-sea interaction, planetary boundary-layer processes and mesoscale meteorological processes. As one of the core investigators of the GALE, the Principal Investigator was instrumental in designing and executing the experiment. Using the specialized data sets collected during the GALE, the Principal Investigator will carry out a number of studies. The major goals of the research are to describe the mesoscale structure and precipitation producing mechanisms in frontal systems and to investigate the mechanisms responsible for organized mesoscale precipitation features. Included in this research will be unique applications of Doppler radar data and information from numerical models in the diagnosis of mesoscale rainbands.

冬季气旋的迅速发展和加强 在沿海地区，这是一个主要的天气预报问题。 沿着美国东海岸， 气旋风暴和锋面系统经常发生在沿着， 多米尼加的沿海地区。 这些天气系统可能会导致 在人口稠密的东北走廊， 冻雨、大雪、暴风雪和 广泛的海岸侵蚀。 一个复杂的相互作用的冷 大陆空气，温暖的洋流，大气层 干扰和当地地理都似乎有助于 这些系统的快速发展;然而，这些过程 对这些现象的了解不够，而且往往预测不佳。 1986年1月至3月， 研究该地区冬季风暴的是一个由 大学和联邦机构。 创世纪（Genesis of 大西洋低实验），该项目旨在提供 关于海气相互作用的作用的详细资料， 行星边界层过程和中尺度气象 流程. 作为GALE的核心调查员之一， 首席研究员在设计和 执行实验。 利用全球高级生活水平评估期间收集的专门数据集， 主要研究者将开展多项研究。 研究的主要目标是描述中尺度 锋面结构与降水形成机制 系统，并调查负责 有组织的中尺度降水特征 纳入本 研究将是多普勒雷达数据的独特应用， 中尺度诊断中的数值模式信息 雨带
