Abstract:
TAMU Coupled Regional Climate Model (CRCM). This is a locally developed, high-resolution coupled regional model that includes NCAR's Weather Research and Forecast System (WRF) model for the atmosphere and the Rutgers/UCLA Regional Ocean Modeling System (ROMS) to describe the ocean. These two model components are coupled to exchange surface fluxes and state variables at the air-sea interface, in order to improve the accuracy of predictions.

Purpose:
CRCM was used to generate accurate, real-time predictions of atmospheric and oceanic conditions in the Gulf of Mexico at a 3km resolution, as well as of passive diffusion pathways to support the GISR Deep-Release Experiment (July 30-Aug 9, 2012).
