9423556 Panetta The central theme of this research project is to investigate the factors which control the positions, structures, and interactions of the atmosphere's subtropical and polar front jets. Three major topics will be pursued. The first is to examine the factors determining the meridional extent of the Hadley circulation. The second is to investigate whether the degree of separation between the two jets is related to the frequency of blocking formations in the large-scale flow. Finally, the principal investigator will explore the generation of vortices through wave-breaking on tropical jets. The principal tools are idealized, dry hydrodynamic models which differ in physical extent and dynamical regime, depending on the aspect of flow organization being studied. These include several versions of the NCAR Community Climate Model and quasi-geostrophic beta- plane models. ***

9423556 PANETTA该研究项目的中心主题是调查控制大气亚热带和极地前喷头的位置，结构和相互作用的因素。 将追求三个主要主题。 首先是检查确定哈德利循环的子午线范围的因素。 第二个是研究两个喷气机之间的分离程度是否与大规模流中阻断地层的频率有关。 最后，首席研究人员将通过热带喷气机上的波浪探索涡流的产生。 主要工具是理想化的，干燥的流体动力模型，其物理范围和动态状态不同，具体取决于所研究的流动组织的方面。 这些包括几种版本的NCAR社区气候模型和准地斑β-平面模型。 ***
