Land use, soil and topography: horizontal resolution of 30×30s, defined during the WRF pre-processing stage.

OUTPUT


Maps of forecasted fields are shown for Grid 2 (Northeast US) and Grid 3 (High-resolution forecast). Forecast time series (Local Forecast) are given for selected locations. 72 hours forecasting fields:

  • Temperature at 2m: Air Temperature at 2m above ground [degree C]
  • Wind at 10m: Wind field at 10m above ground [m/s)
  • Surface wind gust: Near surface wind field [m/s)
  • Precipitation: 3hr Accumulated Precipitation (Rain + Snow + Ice) [mm]
  • Snow & Ice: 3hr Accumulated Snow and Ice [mm]
