Lomapaseo's comment says it all.
The images in the animation are integrated from satellite images taken every 15 minutes. The animation period is 2.5 minutes, and the integration is done by merging shot #1 with shot #2 etc.. to give the possible changes for 5 periods between observed images using Scalable Vector Graphics.
But that's not the point that Lomapaseo was making. Your own radar has a different aspect of view - horizontal with +/- tilt. What it sees and the depth of penetration are very variable factors, and the picture painted (in plan view) will bear no resemblance to that observed by the satellite, which is taking infra red images of what is on top, and has no way of determining what is below.
