A panel comparing the forecast temperature at approximately 1. Useful for highlighting areas of stratospheric warming. GFS is the global weather forecast model of the US weather service run at an internal resolution of 28 km. Used to monitor the position of the Polar Vortex which can have an influence on winter weather at the earths surface.
Designed to mimic real-time radar images. Les cartes d'échéance de 6h en 6h sont archivées depuis Février WZ offers forecasts up to hours.
Compares the predicted temperature at approximately 1. Compares the predicted mean seal level pressure to what we consider normal a 30 year average from CFSR climatology. Shows the maximum wind gust expected spatially over time. The runs for the 0, 6, 12 and 18Z runs are usually coming in from , , and UTC, respectively.
Monique lange. Region - GFS
Designed to mimic real-time radar images. Units are quantified as an effective temperature in Celsius for Europe, Fahrenheit for North America. Compares the predicted geopontential height at hPa to what we consider normal a 30 year average from CFSR climatology. Original IFS resolution is about 50km 0. We have positive anticlockwise vorticity, which is usually associated with cyclones in the Northern Hemisphere and negative clockwise vorticity, usually associated with anticyclones in the Northern Hemisphere. UKMO The selected variable and region is available, but not for , Compares the predicted mean seal level pressure to what we consider normal a 30 year average from CFSR climatology. Typically around 9 km above sea level, this is where we can monitor the jetstream.
Précaché à Only basic pressure maps are available and forecast data ranges from day 3 to 6. A panel comparing the accumulated precipitation forecast from each ensemble member, the control, their mean, and the deterministic GFS.
The westerly component at 60N is highlighted - a negative value during winter is a sign of a major stratoshperic warming when combined with a poleward increase of temperature north of 60N Compares the predicted temperature at approximately 30 km above sea level to what we consider normal a 30 year average from CFSR climatology. The temperature at which water droplets would begin to condense at 2 m AGL. Gives an overview of variables key for winter weather forecasting.
