GFS Italy: CIN [J/kg]

These maps show the CIN (Convective Inibition), that is the energy needed by an air mass to overcome the resistance to lifting. Values below -300 J/kg indicate a stable atmosphere and therefore such as to make the development of thunderstorms unlikely. A CIN of 0 J/kg means that the atmosphere is not opposed to the formation of storm cells. It's important to see also CAPE and Lifted Index maps to verify if there are sufficient lifting energy available.

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 5:09 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.
