GFS Italy: 500 hPa wind [km/h]
These maps show wind speed (in km/h) and wind direction at 500 hPa pressure level. To know the exact altitude of
the 500 hPa level (which can oscillate between 5000 and 6000 m), see the geopotential maps.
On the top left is shown the UTC initialization time. UTC time is indicated with Z letter (Zulu Time).
On the top right is shown the UTC forecast time.
The maps at 00Z, 06Z, 12Z and 18Z are updated respectively starting from 04.30 AM, 10:30 AM, 4:30 PM, 10.30 PM (CEST TIime).
Forecast model: Global Forecast System (GFS) with 0.25°x0.25° (lat x lon) spatial resolution.
NOTE: in central European countries, when solar time is in effect, the CET time is used, which is equal to UTC +1 hour, while when daylight saving time is in effect, the CEST time is used, which is equal to UTC +2 hours. Right now it is 5:24 UTC.
Notes on GFS forecast maps
The Global Forecast System (GFS) is a National Centers for Environmental Prediction (NCEP)
weather forecast model that generates data for dozens of atmospheric and land-soil variables,
including temperatures, winds, precipitation, soil moisture, and atmospheric ozone concentration.
The system couples four separate models (atmosphere, ocean model, land/soil model, and sea ice) that work
together to accurately depict weather conditions.
GFS is a global model with a base horizontal resolution of 0.25° (28 kilometers) between grid points.
The GFS is run 4 times a day, the temporal resolution covers analysis and forecasts out to 16 days.
