Forecast Models
Weather Research and Forecast Model (WRF)
NSSL real-time WRF model forecast of hourly precipitation valid 12Z 22 nov 06. (current WRF precip loop)
The Weather Research and Forecast (WRF) model is the product of a unique collaboration between the meteorological research and forecasting communities. Its level of sophistication is appropriate for cutting edge research, yet it operates efficiently enough to produce high resolution guidance for front-line forecasters in a timely manner. Working at the interface between research and operations, NSSL scientists have been major contributors to WRF development efforts and continue to provide leadership in the operational implementation and testing of WRF:
- An NSSL scientist developed the fundamental numerical methods that allow WRF to provide an unprecedented combination of accuracy and efficiency in time integration for high resolution models.
- NSSL scientists played integral roles in WRF development as members of various developmental working groups, including groups focusing on model physics, model post-processing, ensemble forecasting, and verification.
- NSSL scientists strongly influenced decisions regarding the operational implementation of WRF by organizing collaborative experimental forecasting and evaluation exercises within the NOAA HWT annual Spring Experiments (2004, 2005)
- NSSL scientists continue to provide a leadership role in the development and implementation of the WRF model by generating and evaluating daily forecasts and serving on the WRF Program Planning Board and WRF Research Applications Board
