The overall goal of this research project is to clarify our understanding of how cyclones (storms) and related atmospheric weather systems form and intensify. The results are likely to contribute to improved skill in weather prediction. Three phenomena will be investigated. The first are extratropical cyclones, particularly cases where there is rapid intensification. The PI hopes to identify the factors which cause cyclogenesis to be explosive. A second area of study is directed at mesoscale solitary gravity waves. These waves represent disturbances with the cyclone that typically are 100 kilometers wide and one hour in duration and cause very rapid pressure falls and sometimes dangerous winds. The third area involves the study of polar lows which are small intense cyclones that develop primarily over the ocean in polar regions. For all three topics, the PI will employ both observational and model- generated data sets. The latter will be taken from simulations done with mesoscale model at the National Center for Atmospheric Research.

本研究项目的总体目标是阐明我们的 了解气旋（风暴）和相关大气 天气系统形成并增强。 结果可能 有助于提高天气预报的技能。 将研究三种现象。 第一类是 热带气旋，特别是在有快速 强化 PI希望确定 会导致气旋爆发 第二个研究领域是 中尺度孤立重力波。 这些波 代表着气旋的扰动， 宽1000米，持续时间1小时， 气压福尔斯下降，有时还有危险的风。 第三区域 涉及到极地低压的研究， 主要在极地的海洋上形成 为所有 三个主题，PI将采用观察和模型- 生成的数据集。 后者将取自模拟 在美国国家大气中心的中尺度模型中完成的 Research.
