The ECMWF seasonal forecasts (SEAS5) are produced every month with a 51-member ensemble at a ...

The idea of the plot is to be able to display each spectral partition as an arrow, with the direction being the mean direction, the length of the arrow the significant wave height, the colour of the arrow the mean wave period with the different arrow head for each partitions.

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.

**These are experimental products and subject to change based on user feedback** These ...

This chart shows the probability that both the wind at 10 m above the earth's surface is ...

Cloud base height is derived by upwardly searching the structure of the model atmosphere to find the altitude where the cloud fraction becomes >1% and...

Significant wave height can be shown to correspond to the average wave height of the top one-third highest waves. The wave period of windsea is generally <10s,...

This display helps with the recognition of clouds of different layers, even when they overlap. Brighter colouring represents greater cloud cover. Cloud-free areas appear white while areas of full cloud cover at all levels appear dark grey (e.g. active fronts)...

This chart shows probability information regarding visibility near the surface derived from the ...

These charts show the probability of various mean periods of ocean waves 10-15 days ahead. The ...

This display helps with the recognition of clouds of different layers, even when they overlap. Brighter colouring represents greater cloud cover. Cloud-free areas appear white while areas of full cloud cover at all levels appear dark grey (e.g. active fronts)...

Mean wave period is the spectrally averaged period of the waves. Wave periods are shown in seconds using colour shading – click on the middle icon to the bottom right for the scale...

These charts show areas where anomalous significant wave heights are likely to occur. These charts are based on the ECMWF ense ...

This display helps with the recognition of clouds of different layers, even when they overlap. Brighter colouring represents greater cloud cover. Cloud-free areas appear white while areas of full cloud cover at all levels appear dark grey (e.g. active fronts)...

Mean total swell wave direction is the spectrally averaged propagation direction of the swell waves (weighted by wave height) of the part of the spectrum that is NOT windsea...

Wave height is the vertical distance between trough and crest. Wave period is the time between the passage of one wave crest and the next. The arrow direction is the direction the waves are moving towards...
