The charts show the evolution of existing and potential tropical cyclone activity. ...
Interval/period: N/A
These charts aim to point towards areas where anomalous weather is likely to occur. ...
Interval/period: N/A
These diagrams show verification scores for significant wave height and 10 m wind for three ...
Interval/period: N/A
These charts show the the wave energy flux (in kW m⁻¹) calculated as the integral, over all forecast wave frequencies and wave directions, of the product of the wave group speed and the two-dimensional energy wave spectrum...
Interval/period: N/A
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...
Interval/period: N/A
Precipitation totals include all precipitation types (rain, snow etc.) (in mm of rainfall or rainfall equivalent) falling in 6 hour or 12 hour periods using colour shading...
Interval/period: N/A
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)...
Interval/period: N/A
These charts show areas where anomalous significant wave heights are likely to occur. These charts are based on the ECMWF ense ...
Interval/period: N/A
Ensemble Mean Sea Level Pressure (MSLP) is the mean MSLP of the ensemble members (in hPa) and detail is smoothed out. These charts show surface pressure patterns...
Interval/period: N/A
These charts show the mean and variation in the latest ECMWF ensemble forecast (ENS). ...
Interval/period: N/A
This chart shows the probability that both the wind at 10 m above the earth's surface is ...
Interval/period: N/A
The ECMWF seasonal forecasts (SEAS5) are produced every month with a 51-member ensemble at a ...
Interval/period: N/A
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)...
Interval/period: N/A
**Note:** In **June 2023** ECMWF implemented a **major upgrade ...**
Interval/period: N/A
The ECMWF seasonal forecasts (SEAS5) are produced every month with a 51-member ensemble at a ...
Interval/period: N/A
This chart provides information on the verification of forecasts of the number of tropical ...
Interval/period: N/A
At any location over the oceans, there is a spectrum of waves which describes how much wave energy is present for given wave frequencies and direction of propagation...
Interval/period: N/A
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,...
Interval/period: N/A
These diagrams compare Continuous Ranked Probability Skill Scores (CRPSS) of ECMWF with ...
