Analysis of the Data from North Dakota Thunderstorm Project

地球上大多数潮湿的地区都会出现飑线。 在 美国的大平原， 季节性降水来自于飑线。 此外，严重 天气通常有飑线系统。 首席研究员将继续研究 飑线的结构。 这将是一个观察和 数值模拟工作使用的数据收集在北 达科他州雷暴计划。 这其中一个特别独特的方面 研究表明，广泛的飞机和遥感 在飑线的早期阶段， 辈子 这提供了一个研究发展的机会， 一个被称为后流入射流的特征已经被证明是 这是飑线的一个重要动力特征。

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.
