OK let me try to explain why I am confused. Take 2 columns of air, lets say 100,000ft high.
One is warm and one is cold. At a point 5,000 foot from the surface, one column has 95,000 feet of cold, dense and heavy air above it and the other has 95,000 feet of warm, less dense and lighter air above it. At this 5000 foot point, the pressure will be higher in the cold air. The point at which the same amount of warm air would produce the same pressure must be lower right?? Where am I going wrong??
