31.          Why do weather people like to talk about “the Jet Stream?”

 

 

 

 

 

32.          The reason for the Jet Stream…

 

a.       If you assume that air is distributed evenly throughout the Earth’s atmosphere, why are the Hadley cell, Ferrel Cell, and Polar different heights?

 

 

 

 

b.      Where is there more air pressure, at the top, middle, or bottom of the atmosphere?

 

 

 

c.       Where is air pressure greater, at point B or point A?  Why?

 

 

 

 

d.      Will wind “try” to flow from A to B or from B to A? 

 

 

 

e.      Will that wind curve eastward or westward?  Why?
