Wow, this is super cool!
Thank you!
This process will work for other geospatial datasets with velocity data. We make streamlines from the velocity vector field data. This could be done for the atmosphere or other geophysical datasets from sources such as NOAA and NASA.
The heavy lifting is done by matplotlib with matplotlib.org/stable/api/_as_gen/...
The arguments I fed it were trial and error to make a nice looking plot. The 8 that occurs as an argument is the density parameter for spacing between the streamlines.
Also, about the cute way of making progress bars and combining into an animation using ImageMagick and ffmpeg, the bash script is fairly general and can be modified for other uses.
