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.

GFS Europe: Air temperature trend [°C] and Geopotenziale trend [hPa] at 500 hPa

These maps show the differences between predicted and current geopotential height (in m) at 500 hPa. White areas on the maps indicate geopotential variations between -50 m e +50 m compared to the current ones, color areas between yellow and red indicate an increase in geopotential compared to the current one, while color areas between light blue and purple indicate a decrease. The resulting differences in m are shown on the vertical colorbar.
Similarly, differences on temperatures at 500 hPa are also calculated, with red lines in case of an increase of at least 2 °C or blue lines in case of decreases at least 2 °C.

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 0.5°x0.5° (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 7:11 UTC.
