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.

飑线出现在地球上大多数潮湿的地区。 在美国大平原，生长季降水的很大一部分来自飑线。 此外，飑线系统中恶劣的天气也很常见。 首席研究员将继续研究飑线的结构。 这将是利用北达科他州雷暴项目期间收集的数据进行的观测和数值建模工作。 这项研究的一个特别独特的方面是，在飑线生命周期的早期阶段存在广泛的飞机和遥感观测。 这提供了一个研究称为后流入射流的特征的发展的机会，该特征已被证明是飑线的动态重要特征。
