Question

Quizplus · Accepted Answer

Precipitation measured by weather radar is based on the scattering of radiation by falling droplets, ice crystals, and hailstones. The radar sends out pulses of electromagnetic radiation, which are scattered in all directions when they encounter precipitation. The amount of scattering depends on the type, size, and concentration of the precipitation particles. The radar then receives some of the scattered radiation back, which is processed to produce a precipitation image.
