Regional Climate

Weather Research and Forecasting Model
WRF is a mesoscale numerical weather prediction system used for many different kinds of atmospheric research. Created by a partnership spanning more than 150 governmental, academic, and private organizations worldwide and continually augmented and improved by the research community, the WRF model has been used to simulate regional climate for more than a decade.

Community Land Model
CLM is a community model that simulates simulates the biophysical, hydrological, and biogeochemical processes by which terrestrial ecoysystems affect, and are affected by, climate. In addition to being the land surface model used in RESM and CESM, CLM also provides the basis for much of PRIMA’s distributed water supply and demand capability. The Model for Scale-Adaptive River Transport, or MOSART, model has been coupled to CLM to simulate river dynamics. Several improvements and enhancements made to CLM through the PRIMA initiative have been included in the official release of CLM4.5.

Regional Ocean Modeling System
ROMS is a community ocean model used for a variety of applications. It includes several coupled component models for biogeochemical, bio-optical, sediment, and sea ice. The coupled WRF-ROMS model has been shown to produce skillful simulations of ocean barrier layers and their effects on tropical cyclone intensification.

The Regional Earth System Model, or RESM, provides dynamically downscaled climate information for other models in the PRIMA framework. RESM couples the Weather Research and Forecasting (WRF) atmospheric model, the Community Land Model (CLM), and the Regional Ocean Modeling System (ROMS) using the Community Earth System Model (CESM) flux coupler. RESM uses boundary conditions from global climate models or global reanalyses. For the initial PRIMA numerical experiments, RESM is being run over the conterminous United States at 20-kilometer resolution using boundary conditions from CESM under two different scenarios of global climate forcing.
