Satellite Meteorology



Created by UW-Madison, 2002

1) True or False – Satellites can detect tornadoes
FALSE, tornadoes form from the base a severe thunderstorm. However, satellites can detect conditions that are favorable for tornadoes and are excellent tools for tracking these storms.

2) To qualify as a hurricane or typhoon a storm must have sustained winds exceeding ______ mph.
74 mph don't forget they need to be sustained winds

3) Radar is an acronym for …
"radio detection and ranging

4) An “overshooting top” is associated with what type of storm? What does it look like on satellites? Why is it so important?
Overshooting tops locate the strongest updraft in a thunderstorm and the place where severe weather is most likely to develop at the surface. On satellite images they look like a small bubble of clouds on top of a flattened anvil cloud, frequently described as looking like a cauliflower head.

5) Which remote sensing instrument flown on satellites is critical for sampling clear air regions of the atmosphere prior to the development of severe weather? What do they measure?
Sounders (Vertical Atmospheric Sounders) provide vertical profiles of temperature, pressure water vapor and trace gas profiles of the atmosphere.

6) What is a storm surge and what type of weather system is it associated with?
A storm surge is a wall of seawater pushed onshore by persistant hurricane winds.

7) What type of storm causes more deaths on an annual basis, tornadoes or thunderstorms?
Lightning and straight line winds associated with thunderstorms cause more deaths annually in the United States than tornadoes.
