Thanks @Gkikas-LGPZ . I will summarize below in case of others have the same question:
In ECMWF model output, it's called 10fg(10fg1, 10fg3, 10fg6);
In GFS model, it's called GUST.
Gust is defined as the maximum 3 second wind at 10 m height as defined by WMO.

RE: How to forecast gust wind
@idefix37 Great, thanks!
At first I think at least there must be some gust factor, either a constant or a exponential formula. But now I realized that the gust is directly output from the model. That's even better! -
RE: What is a wet snow?
@gkikas-lgpz
As I searched the posts, I found your proposal which ask the windy developers do improve ECMWF meteogram by involving PTYPE Precipitation type (ID: 260015 GRIB2) and SF Snow fall (ID:144).
https://community.windy.com/topic/4755/rain-or-snow/13The description is here:
https://www.ecmwf.int/en/forecasts/datasets/set-i#I-i-a_fcFor PTYPE:
Describes the type of precipitation at the surface at the validity time. A precipitation type is assigned wherever there is a non-zero value of precipitation in the model output field (however small). The precipitation type should be used together with the precipitation rate to provide for example indication of potential freezing rain events. Precipitation type (0-8) uses WMO Code Table 4.201Values of ptype defined in the IFS:
0 = No precipitation
1 = Rain
3 = Freezing rain (i.e. supercooled)
5 = Snow
6 = Wet snow (i.e. starting to melt)
7 = Mixture of rain and snow
8 = Ice pellets -
How to forecast gust wind
Hi, Thanks for your great work in creating Windy.
Recently I noticed the spatial pattern of gust wind is very similar to the wind forecast, the difference is only in the magnitude, like in the following figures. Is this the result of multiplying a factor? Or any other mechnism to forecast gust wind?
Hope for an answer sincerely.
