What frequency does weather radar use?

What is the weather radar forecast?

A weather radar is a type of radar used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity. Weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation.

How does the weather radar work?

Weather radar consists of a rotating dish protected by a large white dome; this dish sends pulses of energy (the radar beam) into the atmosphere to detect objects like rain or hail. If the radar beam encounters an object, some of the radiation will bounce off of it and return to the radar site.
