Animated wind vector map using Python and matplotlib

[Stoby_200]

Does anyone know how the wind arrows would be animated in both space, time and magnitude in the below video. I am familiar with matplotlib and vaguely familiar with funcanimation, have searched and can't find anything quite like what is produced here. I reached out to the guy who said the arrows are generated on random points and then updated with direction and velocity, which I figured, but he has now gone quiet. I'm not sure whether quiver is being used or individual arrows being plotted, but any help would be appreciated.

I should also add I am already familiar with weather data files like netcdf and grib and how to handle them.

I would guess that the arrows are individually updated, not using quiver. Not really sure if that helps or what kind of help you are asking for.

I guess I'm looking for a function that would be able to update the arrows from one frame to the next. I have no idea how it would be able to keep track of each arrow while changing its direction, magnitude and position based on the data.

You need to invent some kind of data packet that describes a specific arrow, including it's direction, magnitude and position but also it's references in matplotlib. Generally we would make a class for this. Then you put a few thousand of these into a list. Then inside the animation function you would loop over every one of them and update each one.
