**This product shows ENS meteograms from next model version of IFS cycle 50R1 that is planned ...**

**Next IFS version (cycle 50r1)**. This product shows the probability of visibility (%) in 2 ...

(Next IFS version - CY50R1) Probability of precipitation type (%) in precipitation rate categories ...

(New IFS cycle 50R1) The Vertical Profiles display the vertical structure of the forecast model atmosphere in a familiar user friendly way. The vertical structure of temperatures (red) dewpoints (green) and dewpoint depressions (blue) from each ENS member ...

Bulk Wind Shearcharts show the vector value (in wind arrow form) of the shear between the low level, near surface level (10 m) and a mid-tropospheric level (about 6 km)...

The surface wind is influenced by the roughness of the earth's surface and is likely to be less strong, and a little backed (in the northern hemisphere) or veered (in the southern hemisphere)...

This chart shows the anomaly in the wind speed at 10 m above the earth's surface (in m/s) ...

These charts show surface pressure patterns. Areas of high pressure (anticyclones) are usually associated with settled weather...

Dew Point Temperature at 2 m above the earth’s surface gives an indication of conditions which a person will experience or feel. High dewpoint temperatures inhibit heat loss from the body by perspriation and...

Temperatures at 2 m above the earth’s surface and winds at 10 m above the earth’s surface approximate most closely to the conditions that a person would experience.

Air temperatures at 2 m above the earth's surface approximate most closely to the conditions a person would most likely experience...

This chart shows the anomaly in the temperature at 2 m above the earth’s surface (in °C) during a 24 hour period immediately preceding the chosen valid date/time...

The 850 hPa level is usually just above the boundary layer and at this level the day-night variation in temperature is generally negligible...

500-1000 hPa thickness is a measure of the mean temperature of a column of the atmosphere between these pressure levels and can be used to distinguish between warm and cold air masses and...

These charts show indices which indicate the susceptibility of the troposphere to support free convection. Typical values of the different indices depend on location and...

Various thermall comfort parameters showing thermal comfort

This product is derived from an ensemble of 50 model runs plus Control. Visibility is an ...

Simulated visible images show simulations of the upward flux of radiation (as would be detected by a weather satellite) derived from information using the model representation of temperatures and cloud layers.
