Model information (Last updated: September 1, 2015)

The WRF (version 3.6.1) with Polar Mods (Polar WRF) setting is used in the real-time numerical weather predictions over the Ohio. The Polar Mods were developed by the Polar Meteorology Group at The Ohio State University to better handle Arctic/Antarctic conditions for forecasting purposes. In this configuration, the model consists of 301x301 grid points with a horizontal resolution 10 km. In vertical, the model has 48 terrain-following levels, and the top pressure is set to 10 hPa.

The Ohio WRF Runs contain the following parameterization schemes:

The model starts at 0000/1200 UTC as its initial times every day and produces a 96-hour prediction for the State of Ohio. The initial and boundary conditions are interpolated from the daily 0000/1200 UTC run of the Global Forecast System (GFS) issued by the National Centers for Environmental Prediction (NCEP).
