Which quantity does the barometric formula predict?

  • A.Pressure as a function of height for a given temperature profile
  • B.The temperature at each height given the pressure measured at the surface beneath the column of air
  • C.The density at the surface
  • D.The rate at which the pressure at a fixed point changes with time as a weather system passes overhead

Answer: A

Integrating the hydrostatic equation with an assumed temperature profile gives pressure as a function of height, which is the barometric formula. The isothermal case gives an exponential and a constant lapse rate gives a power law. Altimeters are calibrated using the constant lapse rate form of the standard atmosphere.
