许多对于理解和 预测天气是破坏人类活动发生在 气象学家称之为中尺度。 中尺度现象是 没有很好地被操作天气网络采样;因此， 特别是通过幕式现场试验， 旨在研究中尺度过程。 主要研究者有两个使用数据的目标 已经完成的现场项目。 第一 是计算水、感热、动量和 位涡和检查的大小， 中尺度对流背景下的锋生过程 系统. 这一数据集的独特之处在于，它允许， 第一次，预算公式中的所有项都要计算。 一个数值模型也将被用来帮助解释 结果 第二个重点是收集研究报告， 阐明中尺度对流的结构和动力学 系统. 这些研究包括雷达资料的气候学， 美国和欧洲以及数值模拟。

Many of the factors that are critical for understanding and predicting weather that is disruptive to human activity occur on what meteorologists term the mesoscale. Mesoscale phenomena are not well sampled by the operational weather network; therefore, progress is made through episodic field experiments specially designed to study mesoscale processes. The Principal Investigator has two objectives using data sets from already completed episodic field programs. The first is to calculate budgets of water, sensible heat, momentum and potential vorticity and to examine the magnitudes of frontogenetical processes in the context of mesoscale convective systems. This data set is unique in that it allows, for the first time, all terms in the budget equations to be calculated. A numerical model also will be used to help in interpreting the results. The second thrust is a collection of studies aimed at elucidating the structure and dynamics of mesoscale convective systems. These studies include climatologies of radar data over the U.S. and Europe and numerical modeling.
