  10. 17. rotation of air around a high pressure center in the opposite direction of Earth's rotation
  11. 18. Short term fluctuations (days, weeks) in temperature, precipitation, and humidity resulting from rapidly forming and decaying weather systems
  12. 19. Front When a warm air mass overtakes a cold air mass.
