DWD Ocean Waves - Wind and Waves
|Provider:||Deutscher Wetterdienst, DWD, Germany|
|Update frequency:||every 12 hours|
|Resolution:||0.25°, 15.0nm, 27.8km|
|Model duration:||31 forecasts starting at 0 hr, ending at 7 days|
|Parameters:||wind, wind wave, swell, swell/wave combined|
|GRIB model date:||Sat Sep 25 00:00:00 2021 UTC|
|Download date:||Sat Sep 25 04:31:22 2021 UTC|
|Download delay:||4hr 31min|
Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.
The DWD World Wave model is a global model, generating wave information, including wind waves and swell.
This model, unlike the NOAA WW3 model, also includes information on the Mediterranean. There is however higher resolution Mediterranean information available, by using the DWD Europe model.
Ocean wave forecasts based on DWD-Model ICON
The numerical wave model represents an integral part of the operational weather prediction system. Therefore, wave forecasts directly depend on the forcing by analyzed and forecast 10m-winds of the atmospheric model ICON.
Internally, the wave model describes the local sea state as a 2-dimensional distribution of wave energy with respect to wave period and the direction of propagation. In the present version, a wave spectrum represents 36 directions und 30 wave periods from 1.5 to 24 seconds.
