  1. Jet Stream

  2. Wasaburo Oishi, Japanese Discoverer (1920s)

  3. Fu-Go Balloon Weapon

  4. Strahlstromung (German) for “jet stream” first used in 1939 • Big effects on bomber flights during WWII

  5. Jet Stream winds are not uniform

  6. 250 mb isotach

  7. Main Upper Tropospheric Jets Closely Associated with the Tropopause

  8. Tropopause

  9. Tropopause Heighthttp://www.atmos.washington.edu/~hakim/tropo/tropo.html

  10. Subtropical Jet Stream

  11. Subtropical Jet Stream Often Associated with a cloud band

  13. Jet Stream’s Relationship to Temperature Can Be Shown through Thermal Wind Arguments

  14. 250 mb isotach

  15. 1000-500 mb thickness-large thickness gradient and thus thermal wind near jet core

  16. Or alternatively…

  17. The Jet Stream Recall the horizontal temperature effects on the pressure: 500 mb 700 mb 850 mb Psurface Warm Cold

  18. The Jet Stream Consider the balance of forces at each level: Co PGF 500 mb 700 mb 850 mb Ps Warm Cold

  19. There are a variety of jet stream configurations that are well-known
