Wind speed at 200 hPa highlights the jet stream (areas of strong winds in the upper troposphere) which can help identify movement and development of depressions...
Interval/period: N/A
Wind speeds near the surface are roughly proportional to the distance between isobars so closely packed isobars mean strong surface winds...

This shows the daily distribution and evolution of mean zonal wind at 10hPa at 60N or 60S. ...
Interval/period: N/A
These charts show areas where anomalous 10 m wind gusts are likely to occur. These charts are based on the ECMWF ensemble fore ...

Spread usually, but not always, increases with forecast range. Spread refers to the uncertainty of the values of a parameter but it does not necessarily refer to the flow patterns...
Interval/period: N/A
The ensemble mean is the mean value derived from all the 50 ensemble members plus the control member. This value attempts to capture the general picture while smoothing out spurious detail...
Interval/period: N/A
These charts show the mean and variation in the latest ECMWF ensemble forecast (ENS). ...

Maximum Wind gusts at 10 m above the earth's surface during the 6 hour period previous to the selected validity time are shown using colour shading. 10 m wind gusts are a post-processed product...

The charts show the forecast value of the vertically integrated total column water (vapour + cloud water + cloud ice but with no precipitation included) in units of kg m⁻²...
