7.  [6] a) Freida the balloonist boards her balloon and finds that she can travel upwards for 1 km by adding just a tiny amount of heat to her balloon. What is the atmospheric lapse rate?

b) At the 1 km level, she enters a flat-bottomed cloud.  What happens to the lapse rate?

c) On another day, she finds that she must add enough heat to warm her balloon by 3C in order to travel upwards 1 km.  What is the average lapse rate in the lowest 1km?

8.  [4] Earth's average surface temperature is 288 K and its average lapse rate is about -6K/km.  At what altitude is the effective radiating temperature found? (4 points)

9.  [5] Explain why midlatitude west coast regions (e.g., western Washington and Oregon) experience much cooler summers than east coast locations at the same latitude?  Be sure to mention both the roles of hemispheric-scale atmospheric circulation and coastal upwelling.

10.  [5] On most days at a given location over land, relative humidity is highest early in the morning and lowest in early afternoon.  Explain.
