The Hypsometric Equation 3. You measure the pressure at Edmonton to be 950 hPa, and the average virtual temperature below the 800 hPa pressure level is -200C. (a) What is the height above ground of the 800 hPa surface? 3 marks (b) Given the same observations as in (a), you wish to include your pressure measurements in Environment Canada's national map. What normalized pressure do you give them, knowing that Edmonton is 645 m above sea level? 3
