Thanks a lot for the input and clarifications 🙂. This is really interesting. I have no formal training in meteorology, but work in somewhat related fields (engineering, measurements and modelling/simulations). I guess that challenges with grids/meshes and how to resolve models might have some similarities. Anyhow, very interesting, and thanks again 🙂👍🙏.

Thanks for the info. Here is a screenshot.

Not 2x average but ~80% increase at 15.00. Still quite high?
But maybe this is due to some sort of "terrain effect" in the model?Here is a screenshot from a measurement site very close to the location above:

Wind gusts in ECMWFposted in General Discussion
Hello all,
I use windy for sailing, boating, being outdoors and as a everyday weather tool. I think it is great :) .However, something that I cannot understand is the values of wind gusts. In particular for the ECMWF model. It is quite often that they are almost about 2x as high as the average wind. So given a forecasted average wind of 10 m/s, wind gusts are forecasted to 20 m/s.
To me this seems as unrealistic high values. Imagine that you are out sailing on the sea with a wind of 10 m/s, then a gust at 20 m/s or 18 m/s would be extremely strong...!
Maybe I do not understand the concept of wind gust as represented in ECMWF, but from my understanding and experience you would typically experience wind gusts at the open sea as an increase of wind strength in about 20-30%, and in some rare cases up to 40-50%. But usually around 20-30%.
Maybe you guys could help me out and bring som understanding to the question.
Thank you.
