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.

@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!

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/13

The description is here:
https://www.ecmwf.int/en/forecasts/datasets/set-i#I-i-a_fc

For 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 4.201

Values 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

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.

I noticed there is no such wet snow in GFS model, so this is only contained in the ECMWF data?

And what is wet snow? What's the difference between wet snow and rain with snow?

Hi, everyone! I noticed there is a precipitation type called wet snow, as shown in the figure below. This is a new term for me. I'd like to ask what is a wet snow? What's the difference between normal snow and wet snow? How to predict wet snow in Windy?

Great thanks!

@Gkikas-LGPZ In this post(https://community.windy.com/topic/12/what-source-of-weather-data-windy-use), the model output is every three hours for the first 6 days. But isn't gust wind a short period phenomenon which only lasts for several minutes. So is the gust wind prediction a probabilistic one? Or by saying gust wind, it means the maximum wind speed? What's the time resolution of gust wind prediction?

@Gkikas-LGPZ Thanks for your answer. Does this mean that you are post-process the model outcome and then show it in Windy? I guess neither ECMWF nor GFS would forecast gust wind.
