Adaptation of the Weather Research and Forecasting Model to
Create Fine-resolution Forcing Fields for the Hawaii Domain
Xin Zhang, Tim Li, et al.
The 3DVar System of the WRF model has been adapted to assimilate high-quality and fine-resolution satellite and
radiosonde data to create atmospheric surface forcing fields for the domain surrounding the Hawaiian Islands.
These forcing fields can now be used to drive the Hybrid Coordinate Ocean Model (HYCOM) version that has been
downscaled at the IPRC for implementation in the Hawaiian Island region. The four figures show a snapshot of
assimilated 10-m wind (top left), 2-m temperature (top right), net downward longwave radiative flux (bottom left), and
2-m specific humidity (bottom right) fields at hour 18:00 on 8/10/2007.
