Description of Software for Determination of Normal Modes of the NCAR (National Center for Atmospheric Research) Community Climate Model

摘要

The report describes one contribution by Ronald M. Errico of the Large Scale Dynamics Section of NCAR's Atmospheric Analysis and Prediction Division to the development of NCAR's Community Climate Model (CCM). The contribution is the development of software to determine the eigensolutions of a linearized version of the CCM. These eigensolutions may be used for diagnostic analysis, nonlinear normal-mode initialization for numerical weather prediction experiments, or other purposes. Although the software has been designed for the CCM and its initialization, it should be easily modified for use with other models.
