geopotential of the tropopause

geopotential of the tropopause

The point in the standard atmosphere where the temperature stops dropping and becomes constant. This is the dividing line between the troposphere and the stratosphere. It is called the tropopause. Geopotential is the potential energy of a unit mass relative to sea level; it is numerically equal to the work that would be done in lifting the unit mass from sea level to the height at which the mass is located. It is commonly expressed in terms of dynamic height or geopotential height.
