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

  10. 250 mb isotach

  11. 1000-500 mb thickness-large thickness gradient and thus thermal wind near jet core

  12. Or alternatively…

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

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

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