Improve the performance and quality of the cloud effect


Currently, we render the full Earth for each instance of the weather effect. One way to optimize things may be to create a small patch that contours the Earth. For each location, rotate that patch into place and render the cloud effect.

The quality of the cloud effect can also be improved. Currently (and especially near the equator) you can see the 'edges' of the effect because there are fewer points at the center of the mesh. The patch option may help improve this if it contains enough points. You would need to continue to interpolate the opacity as you fan out to the edges.
