Gravity Waves and Occlusions During STORMFEST

9406725 Ramamurthy 冬季风暴是最威胁生命和最具经济破坏性的气象现象之一。 在先前研究的延续中，主要研究人员建议研究两个领域，这两个领域都与与中纬度气旋相关的冬季现象的组织和演化有关。 第一个研究领域涉及中尺度重力波及其相关降水带的起源、演化和结构的研究。 第二个研究重点是研究中纬度气旋的遮挡过程。 这两项研究都将包括诊断和数值建模工作的结合。 这项研究应该有助于加深对中部大陆冬季气旋和嵌入式中尺度过程演化的理解，这些过程对冬季降水的产生发挥着重要的控制作用。 ***

9406725 Ramamurthy Winter storms are among the most life threatening and economically disruptive of meteorological phenomenon. In a continuation of previous research, the Principal Investigators propose to study two areas, both related to the organization and evolution of winter time phenomena associated with mid-latitude cyclones. The first area of research concerns research on the genesis, evolution and structure of mesoscale gravity waves and their associated precipitation bands. The second research thrust is to study the occlusion process of mid-latitude cyclones. Both studies will consist of a combination of diagnostic and numerical modeling work. This research should lead to an increase in understanding of the evolution of mid-continent winter cyclones and embedded mesoscale processes which exert important controls over the production of winter time precipitation. ***
