How do you spell weather radar?

Radar puzzles, there are many products, and they are very professional things. Let me tell you the simplest one. Look at the basic reflectivity chart, which reflects the size and color of precipitation particles in the cloud at that time. From blue to red, the darker the color, the greater the rainfall. When the deepest purplish red appears, it may hail. Everything else is too professional to say clearly in a few words.
