Question

1. Suppose we’re at Barrow Alaska in the early morning in March where temperature inversions dominate. The surface temperature is -40 C and the lapse rate (defined as –dT/dz) is -60 K/km. What is the temperature 100 meters above the surface? What physical process or processes is (are) the likely cause of this inversion?

2. At what depth of water would you need to go for the total pressure (atmospheric pressure at sea level and the water column) to increase by a factor of two above that at the surface of the water?
