Model information (Last updated: January 31, 2020)

The Model for Prediction Across Scales (MPAS v7.0) is used in the real-time numerical weather predictions over the Antarctica. The model consists with variable-resolution meshes (90-25 km) with a single refinement region that is centered on -90.0 latitude, 0.0 longitude. The model outputs were interpolated into 385x385 grid points with a horizontal resolution 20 km for visulational purpose.

The Antarctic MPAS runs contain the following parameterization schemes:

The model starts at 0000 UTC as its initial times every day and produces a 72-hour prediction for the Antarctica. The initial and boundary conditions are interpolated from the daily 0000 UTC run of the Global Forecast System (GFS) issued by the National Centers for Environmental Prediction (NCEP).
