GFS (Global Forecast System) Global Model from the "National Centers for Environmental Prediction" (NCEP) |
| Update: |
4 times per day, from 3:30, 09:30, 15:30 und 21:30 GMT |
| Greenwich Mean Time: |

| Parameter: |
Vertical velocity at 700 hPa the British Isles in hPa/h |
| Description: |
The vertical movement of air is associated with cloud formation,
precipitation, type of precipitation (positive velocity or rising air
motion) or the reduction of clouds, dry an sunny weather (negative velocity
or falling air motion). The vertical velocity is the result of vorticity
advection and temperature advection.
