hypsometric equation

An equation relating the thickness, h, between two isobaric surfaces to the mean virtual temperature of the layer:

where z1 and z2 are geometric heights at pressure levels p1 and p2, respectively; Rd is the gas constant for dry air; Mean temp HypsometricEqu.PNG is the mean virtual temperature of the layer; and g is gravity.

The hypsometric equation is derived from the hydrostatic equation and the ideal gas law.
