Analysis and Simulation of the Large-Scale Circulation Over the Tropical Americas

这项拟议研究的目标是开发一个概念模式，以了解热带美洲的大尺度动态。特别是，这项研究侧重于各种时间尺度上过程之间的相互关系，包括日变化、季节变化、季节变化和年际时间变化。这一效应同样强调使用广泛的数据库分析观测到的环流行为，并使用一系列数值模式来模拟这种环流。这项工作之所以重要，是因为它旨在确定控制热带美洲上空大尺度环流、气候学和对流活动变异性的主要特征和机制。

The objective of the proposed study is to develop a conceptual model for understanding the large-scale dynamics over the tropical Americas. In particular, the study focuses upon the interrelationships which occur between processes over a wide range of time scales including diurnal, intraseasonal, seasonal, and interannual temporal variability. This effect emphasizes equally the analysis of the observed behavior of the circulation using an extensive data base and the simulation of this circulation using a hierarchy of numerical models. This work is important because it aims at identifying the primary characteristics and mechanisms which govern the large scale circulation, the climatology, and the variability of convective activity over the tropical Americas.
