I have a random question - what layer are you using to draw the country borders on the base map? It really stands out, and helps tie the styling together.
The countries layer is using this dataset from MapTiler [1] which is also the service I'm using for all the base maps and vector tile data. I then used interleaved layers [2] in Deck.gl / MapLibre to place the wind layers behind the country outlines.

deck.gl focuses on vector data, whereas WeatherLayers GL adds raster capabilities. Actually, WeatherLayers GL is mostly custom WebGL shaders that could be implemented outside of deck.gl as well. The major reason why deck.gl is used is that it serves as an integration layer for popular map libraries. I've written deck.gl-leaflet [1] plugin myself.
