@rekel You can use this tool from the NOAA based on GFS model: Hysplit gives you the trajectory of the air parcel reaching a location, at different altitude above this location. https://www.ready.noaa.gov/HYSPLIT.php On Windy there is a plugin which works in the other way. It gives the air trajectory from a location. It is useful for air balloon trips.

@ss1007 I'm happy it works for you!

https://m. see wind flow at 00:9:53 @jerrajerra Remember that global models have a resolution between 9km and 22km ! So it’s impossible to display such a picture by weather models. What they show here is like a video game at very high resolution. For the weather forecast, maybe in 20 or 30 years....
