How to read Weather Radar Puzzle

Radar puzzles, which have many products, are very professional. Let me tell you the simplest one. Look at the basic reflectance map, which reflects the size of the precipitation particles in the clouds at that time, and the color depth, from blue to red. The darker the color, the greater the rainfall. When the deepest purple-red appears, it is possible It's going to hail. Everything else is too professional and cannot be explained clearly in just a few sentences.
