At some location and at some initial time the atmospheric pressure at sea level is 1000mb and the temperature between sea level and 900mb surface is 0°C. The atmosphere is in hydrostatic balance. (a) What is the height above sea level of the 900mb surface? (b) Over a period of one day the temperature of sea level and the 900mb surface rises from 0 to 3°C, but the height of the 900mb surface does not change. What is the new sea level pressure? (c) Give a very brief physical explanation for your answer to (b).
