In the Northern Hemisphere, air around a low-pressure area flows

  1. clockwise, outward and downward
  2. counterclockwise, inward and upward
  3. counterclockwise, outward and downward
  4. clockwise, inward and upward
Show the answer

B. counterclockwise, inward and upward

Air spirals counterclockwise into a low and rises, which cools it and produces cloud and precipitation. Around a high it flows clockwise, outward and downward, usually bringing better weather.

Which conditions are typical of a stable air mass?

  1. Cumuliform clouds, showery precipitation and good visibility
  2. Stratiform clouds, showery precipitation and good visibility
  3. Cumuliform clouds, steady precipitation and poor visibility
  4. Stratiform clouds, steady precipitation and poor visibility
Show the answer

D. Stratiform clouds, steady precipitation and poor visibility

Stable air resists vertical motion, so clouds form in layers, precipitation is steady, the air is smooth and haze or smoke stays trapped. Cumuliform clouds, showers, turbulence and good visibility go with unstable air.
