High-Resolution Numerical Weather Prediction


My group runs high-resolution deterministic forecasts using the NCAR WRF model (down to 1.3 km grid spacing) and a large high resolution ensemble (25 members, 4-km grid spacing), both twice a day.  We feed this model output into a variety of applications, ranging from smoke dispersion and air quality models, to tailored support applications like Seattle SnowWatch and WindWatch.  We also carefully verify our weather prediction models to determine weaknesses and to evaluate the impact of resolution.
