Doppler Radar 17.4
The computer that's a part of a Doppler radar uses the frequency changes • It show directions and speeds of the winds blowing around the raindrops, insects and other objects that reflected the radio waves.
Doppler Radar • Waves reflected by something moving away from the antenna change to a lower frequency. • Waves from an object moving toward the antenna change to a higher frequency.
Predictions • Scientists and forecasters have learned how to use these pictures of wind motions in storms, or even in clear air, to more clearly understand what's happeningnow and what's likely to happen in the next hour or two.
Radar images are color-coded to indicate precipitation intensity.
Squall Line • An organized line of thunderstorms is known as squall line.
Hook- tornado • These are commonly found in a single thunderstorm. When this occurs, the thunderstorm is producing a circulation and possibly a tornado. The rain gets wrapped around this circulation in the shape of a hook.
