9733127 Martin This award is made under the NSF CAREER Program. The principal investigator, Dr. Martin, will carry out an integrated research and teaching program in which extensive use will be made of 4-dimensional animated output from a numerical model. The research component is focused on an investigation of the structural and dynamical evolution of cyclones in the relatively unstudied late stages of the cyclone life cycle, including cyclolysis. The study will employ the case study approach and will include simulations with a state-of-the-art, non-hydrostatic, mesoscale model and the use of potential vorticity diagnostics. Special attention will be given to the role of latent heat release on the post-mature stage behavior of extratropical cyclones. The educational component involves a variety of activities, all of which will use tailored versions of the same 4-dimensional model animation as a means of illustrating complex atmospheric phenomena. These activities fall into two categories: (1) outreach education to local primary and secondary schools and (2) curriculum enhancement, at all levels in the university classroom, through the development of course-specific World Wide Web links to current animated forecast model data.

该奖项由美国国家科学基金会职业计划授予。首席研究员马丁博士将开展一项综合研究和教学计划，在该计划中，将广泛使用数值模型的四维动画输出。研究部分的重点是在旋风生命周期的相对未被研究的后期阶段，包括旋风溶解阶段，对旋风的结构和动力学演变进行调查。该研究将采用案例研究方法，包括使用最先进的非流体静力学中尺度模型进行模拟，并使用潜在涡度诊断。本文将特别关注潜热释放在温带气旋成熟后阶段行为中的作用。教育部分包括各种各样的活动，所有这些活动都将使用相同的4维模型动画的定制版本，作为说明复杂大气现象的手段。这些活动分为两类：(1)向当地中小学进行外展教育；(2)通过开发与当前动画预测模型数据相关的特定课程的万维网链接，在大学课堂的各个层次加强课程。
