Application of the Weather Research and Forecasting (WRF) Model in Antarctica

Jordan G. Powers, NCAR, Boulder, CO; and K. W. Manning and M. M. Lambertson

The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale model designed for both operational forecasting and research. WRF Version 2 has recently been released, the first version to include the capability of two-way interactive nests. This nesting capability now makes WRF attractive for a variety of applications spanning multiple scales.

WRF is tested here in the context of the Antarctic Mesoscale Prediction System (AMPS), an experimental, real-time forecasting system supporting the United States Antarctic Program. AMPS currently uses the Fifth-Generation Penn State/NCAR Mesocale Model (MM5), with modifications specific to polar applications. AMPS will ultimately transition from the MM5, so testing has begun using WRF in the first known application of WRF to Antarctica. The presentation will offer WRF simulations and results, with comparisons to the MM5. Also described will be AMPS and issues in applying WRF to the Antarctic.
