The advanced regional prediction system(ARPS)-A multi-scale nonhydrostatic atmospheric simulation and prediction model. part I:model dynamics and verification

摘要

A completely new nonhydrostatic model system known as the Advanced Regional Prediction System(ARPS) has been developed in recent years at the Center for Analysis and Prediction of Storms(CAPS) at the University of Oklahoma. The ARPS is designed from the beginning to serve as an effective tool for basic and applied research and as a system suitable for explicit prediction of convective storms as well as weather systems at other scales. The ARPS includes its own data ingest, quality control and objective analysis packages, a data assimilation system which includes, single-Doppler velocity and thermodynamic retrieval algorithms, the forward prediction component, and a self-contained post-processing, diagnostic and verification package.
