The Weather Research and Forecasting (WRF) Models
The Weather Research and Forecasting (WRF) Models are operated by the Department of Meteorology at University of Hawai‘i.
Hawaiian Islands WRF Models
Boundaries of the model regions are outlined in yellow. The larger box outlines the Hawai‘i WRF model, and the smaller boxes represent the island scale model regions.
Hawai‘i WRF Model (Regional Scale)
The Hawai‘i Islands WRF model is run daily to provide a 7-day weather forecast for the variables, air temperature, air pressure, air relative humidity, rainfall, wind, surface net longwave radiation flux, and surface net shortwave radiation flux. The horizontal grid resolution is 6km. This model is useful for analyzing near weather patterns that are approaching, present, or departing the islands. Model output figures are provided by the Department of Meteorology, here.
Maui-Oahu WRF Model (Island Scale)
Similar to the Hawai‘i Islands WRF model, this model is run daily to provide a 7-day weather forecast with the same variables. However, the horizontal resolution is smaller, approximately 2km. Model output figures are provided by the Department of Meteorology, here.
Oahu WRF Model (Island Scale)
While this weather model provides the same variables as the other WRF models, it is run daily for a 3.5-day forecast. The resolution is 1.5km, allowing for a clearer picture of localized weather events. Model output figures are provided by the Department of Meteorology, here.
Western North Pacific WRF Models
Boundaries of the model regions are outlined in yellow. The larger box outlines the Western North Pacific WRF model, and the smaller box represents the Mariana WRF model region.
Western North Pacific WRF Model (Regional Scale)
The Western North Pacific WRF model is run daily and produces a 7-day hourly forecast for this region and areas farther west past the Phillippine Islands. The model has a resolution of 12km, and its main purpose is to monitor weather patterns approaching, present, or departing this entire region. Model output figures are provided by the Department of Meteorology, here.
Mariana Islands WRF Model (Island Scale)
The Mariana Islands WRF model has a resolution of 3km and is run daily to create a 7-day hourly forecast for Mariana Islands. Model output figures are provided by the Department of Meteorology, here.
American Samoa WRF Model
The boundary of the American Samoa model region is outlined in yellow.
American Samoa WRF Model (Island Scale)
The American Samoa WRF Model is run daily and produces a 7-day forecast. The grid has a resolution of 3km. Its main purpose is to monitor weather patterns approaching, present, or departing this entire region.
