Research in Atmospheric Dynamics

“大气动力学研究”根据该奖项，首席研究员将在大气动力学的两个领域进行研究。第一种是对山脉背风处风暴或气旋形成的理论研究，或称背风气旋形成。我们将详细研究气旋形成的两个方面：(1)初期扰动与山障壁之间的相互作用；(2)急流条纹作为风暴发展的动力的作用。这项研究是班农博士之前工作的延伸。第二个研究领域涉及对大气动力学的一个主要概念模式，即准地转理论的一个方面的重新检查。这个理论采用了适用于大尺度大气运动的运动方程的某些近似。首席研究员计划测试一种新的方程形式的有效性，这种形式更好地代表了数值模型下边界的条件。这两项研究对于提高我们对大尺度大气运动的理解都很重要。

"Research in Atmospheric Dynamics" Under this award, the principal investigator will pursue studies in two areas of atmospheric dynamics. The first involves a theoretical study of the formation of storms or cyclones in the lee of mountain ranges, or lee cyclogenesis. Two aspects of cyclogenesis will be examined in detail: (1) the interaction between the incipient disturbance and the mountain barrier and (2) the role of jet streaks as the impetus for the developing storm. This study represents an extension of some of Dr. Bannon's previous work. The second research area involves a reexamination of one aspect of a major conceptual model of atmospheric dynamics, the quasi-geostrophic theory. This theory employs certain approximations to the equations of motion which are applicable to large-scale atmospheric motion. The principal investigator plans to test the validity of a new form of the equations which better represents conditions at the lower boundary of numerical models. Both of these studies are important for improving our understanding of large-scale atmospheric motion.
