  1. General Circulation of the Atmosphere

  2. Hadley Cell

  3. Monsoons A monsoon is a term from early Arabs called the "Mausin," or "the season of winds." This was in reference to the seasonally shifting winds in the Indian Ocean and surrounding regions, including the Arabian Sea.

  5. Monsoon

  6. Monsoon Origin

  7. West African Monsoon

  8. Southwest U.S. Monsoon

  9. The Jet Stream • A long, narrow current of strong winds in the midlatitudes that is generally found in the upper troposphere and lower stratosphere (roughly 25,000-35,000 ft, 400-250 hPa). • First became obvious during WWII as high flying aircraft was sped up and slowed down on their missions. • Strongest can exceed 200 mph. Nearly always from the west in midlatitudes
