2.2 The Atmosphere's Pressure Structure: Hydrostatic Equilibrium
The atmosphere's vertical pressure structure plays a critical role in weather and climate. We all know that pressure decreases with height, but do you know why?
Pressure and Height in the Atmosphere
Atmospheric pressure is simply the force (weight) exerted by the atmosphere. The average sea level pressure is 1013.25 mb, or 14.7 lb in-2. This means 14.7 ...
