Research Abstract

Comprehensive analyses are made on the output from the general circulation model experiments under idealized lower boundary conditions in the Aqua-Planet Experiment Project(APE), which was participated by 14 modeling groups aiming at climate studies or numerical weather prediction in the world. The results demonstrate a great variety among the structure of tropical precipitation disturbances simulated in the participating models, both in wavenumber space and in real space. In addition, new theoretical insights are obtained, one of which concerns the spectral property of the hierarchical rainfall structure and another concerns the variety of large-scale atmospheric response to a localized sea surface temperature anomaly placed on the equator.
