3. Using Satellite and Radar Imagery to Find Weather Features

4. Radar RAdio Detection And Ranging, used to detect precipitation, and thunderstorms, since the 1940s. Doppler RADAR Detects precipitation. Detects rotation in the cloud.

5. How RADAR Works Energy leaves the antenna, strikes an object, then returns to antenna. Measures: Distance Size Direction

7. Wind

8. Satellite Orbits Geostationary Always located in the same spot of the sky relative to the earth. Can view the entire earth at all times. Can record images as fast as once every minute. View is always from same perspective so motion of clouds over the earth's surface can be computed.

9. Satellite Orbits Polar Orbiting Closer to the earth with an orbit of about 520 miles (833 km) above the surface. Much more detailed images. Excellent views of the polar regions. 4 images per day
