Name the radar system used by most to forecast weather.?

Answer 1

This is the Doppler radar. The Doppler affect in Physics is the change in the wavelength of electromagnetic pulses as they approach you ( they become shorter) or as they go away from you (they become longer). On the radar return these separate signals can be given different colors so as to reveal the motion of the clouds and precipitation that the radar is observing. This capability has assisted meteorologists in determining the likelyhood of tornado occurance for example .

Answer 2

The National Weather Service uses the "88-D Nexrad Doppler Radar", while most TV stations also use their own, but much smaller and less powerful, doppler radars. Doppler just refers the "doppler shift" which is used to measure the speed of the "targets" (rain, hail, etc) detected, and can be used to identify circulations in storms along with finding pockets of strong winds. Most of the time though, you will never see doppler images on TV. Rather, it will be the reflectivity you see, which is a measure of the power returned to the radar. Basically, the radar emits a beam of energy, this gets reflected back to the radar by particles in the air (rain, hail, snow, insects, smoke, etc), and the radar measures how much of that energy is returned. The higher (stronger) the returns, the more the radar "lights up".

Answer 3

Doppler radar which measures the wind direction(provided the wind moves towards or away from the radar)and speed in addition to the intensity of weather echoes usually given by other type of radars.

Answer 4

Its actual name is the WSR-88D. The WSR stands for weather surveillance radar, the 88 is because it was commissioned in 1988, and the D stands for doppler. The other people have explained the mechanisms of it pretty well.

Answer 5

Doppler. It was developed by the navy to tell more about ship's and plane's movements and later adapted by meteorologists. Simply put, It not only tells where percipitation is at, but can tell of its movements in one single sweep of the radar. It only works where precipitation is present such as snow, sleet, rain, or hail. It doesn't reflect off ordinary clouds or it would be pretty much worthless because the cloud would block the radar's ability to see inside the cloud. It tells movements of winds by reflecting off precipitation in the wind.

Answer 6

radar known as a Doppler radar is used to measure the winds

Answer 7

Doppler

Answer 8

That would be Doppler Radar used by Meteorologists - read in my article here: http://physics.suite101.com/article.cfm/doppler_radar_weather_forecasting
