Atmospheric Scene Simulation Modeling and Visualization

摘要

This report provides a review of the Cloud Scene Simulation Model (CSSM), anempirical cloud model developed to support high-fidelity training and simulation applications. TASC and the U.S. Air Force Phillips Laboratory have developed the CSSM to simulate realistic high-resolution cloud and precipitation features within domains defined by larger-scale weather conditions. The current version of the cloud model is built upon the CSSM developed previously for the Smart Weapons Operability Enhancement Program. It contains several key additions and enhancements to satisfy modeling and simulation requirements of the Distributed Interactive Simulation (DIS) community. The model generates four-dimensional (three spatial and time) cloud and precipitation fields using a combination of stochastic field generation techniques and a simple convection model. Internal model parameters have been tuned to fit observed cloud data.
