This is a three-year research project to understand the role of convection in forcing equatorial waves, and the effects of these waves on the dynamics of the middle atmosphere. The tool to be adopted for this investigation is the National Center for Atmospheric Research's Whole Atmosphere Climate/Chemistry Model (WACCM), a comprehensive numerical model spanning the range of altitude from the Earth's surface to the lower thermosphere. The focus of the project are the equatorial waves, forced in the tropical troposphere by transient convection heating, that propagate upward into the stratosphere, mesosphere, and lower thermosphere. It is expected that this project will have broad impact on theoretical, numerical and observational aspects of wave propagation, dynamics, and chemical composition of the middle atmosphere.

这是一个为期三年的研究项目，旨在了解对流在强迫赤道波中的作用，以及这些波对中层大气动力学的影响。 这项调查采用的工具是国家大气研究中心的全大气气候/化学模式，这是一个涵盖从地球表面到低热层高度范围的综合数值模式。 该项目的重点是赤道波，被迫在热带对流层的瞬态对流加热，向上传播到平流层，中间层和低热层。 预计该项目将对波传播、动力学和中层大气化学成分的理论、数值和观测方面产生广泛影响。
