Modeling and Observations of Climate Variability

本研究项目的目的是调查：(a)大气的基本动力学，因为它们与几周到一个季节的时间尺度上的大尺度变率的产生和维持有关；(b)利用日降雨量和雨水探空仪观测的低频变率，以及船舶对地面风矢量的报告；(c)一个耦合的海洋-大气模式的可预测性及其对开发该模式时所作的一些简化和物理规范的敏感性。这是一个重要的项目，因为它将有助于为将来发展模拟中纬度和热带海洋-大气耦合相互作用的模式奠定基础。

The objective in this research project is to investigate, (a) the fundamental dynamics of the atmosphere as they relate to the production and maintenance of large-scale variability on time scales of several weeks to a season, (b) low frequency variability using daily rainfall and rawinsondes observations, and ship reports of surface wind vectors, and (c) the predictability of a coupled ocean-atmosphere model and its sensitivity to some of the simplifications and physical specifications made in developing it. This is an important project since it will help to provide a basis for future development of a model that simulates both mid-latitude and tropical coupled ocean-atmosphere interactions.
