Overview

The WRFv3.6.1 ARW PS:4.4.4.91.2.1.1 configuration is based on the Air Force Weather Agency (AFWA) physics suite and was evaluated by the Developmental Testbed Center (DTC) during the fall of 2014. A functionally similar environment to AFWA operations was utilized, where each configuration was initialized with a 6-hour "warm start" spin-up, including data assimilation. A Contiguous United States (CONUS) domain with 15-km grid spacing was employed for this test covering complex terrain, plains and coastal regions spanning from the Gulf of Mexico, north to Central Canada in order to capture diverse regional effects for worldwide comparability. This configuration is a general application configuration for mid-latitude forecasts.
