Analysis of the Data from North Dakota Thunderstorm Project

狂风线出现在地球上最潮湿的地区。在美国大平原，生长季节降水量的很大一部分来自咆哮线。此外，恶劣天气在狂风线系统中也很常见。首席调查员将继续研究狂风线的结构。这将是一项利用北达科他州雷雨项目期间收集的数据进行的观测和数值模拟工作。这项研究的一个特别独特的方面是，在咆哮线生命周期的早期阶段，存在着广泛的飞机和遥感观测。这为研究一种被称为后方流入急流的特征的发展提供了机会，该特征已被证明是狂风线的一个动力上的重要特征。

Squall lines occur over most moist areas of the Earth. In the Great Plains of the United States, a large fraction of the growing season precipitation comes from squall lines. In addition, severe weather is common with squall line systems. The Principal Investigator will continue research into the structure of squall lines. This will be both an observational and numerical modeling effort using data collected during the North Dakota Thunderstorm Project. A particularly unique aspect of this research is that a wide range of aircraft and remote sensing observations exist on the early stages of the squall lines lifetime. This provides an opportunity to study the development of a feature known as the rear inflow jet which has been shown to be a dynamically important feature of squall lines.
