Why is relative humidity not a good measure of how much water vapor is in the atmosphere? Because you also have to factor in air temp. 2. If the air temperature is 100∞F and the relative humidity is 50%, what is the Heat Index? Does that fit under the category of Caution, Extreme Caution, Danger, or Extreme Danger? 118 F 3. Match the cloud type with its description. Draw connecting lines. Mammatus- Forms in sinking air Cirrus- Thin, wispy cloud Nimbostratus- Low, dark rain cloud Cumulonimbus- Produces lightning Cirrostratus- Produces halo around moon 4.

Why is a dual-polarization radar more useful to a meteorologist than a standard Doppler radar? Doppler Radar works horizontally, dual polarization works vertically as well as horizontally 7. Define orographic clouds. Clouds that develop from the lifting of air that is created by the earth's topographic features like mountains. 8.
