Abstract
A vertical phase shift of the diurnal harmonic of geopotential height S1(Z) in the lower troposphere of low latitudes is shown by a comparison of diurnal harmonic of surface pressure at two surface stations that have an elevation difference close to 4 km. It is inferred from longitude–height cross sections of S1(Z) that this vertical phase shift is caused by the differential response of the lower and mid–upper troposphere to the diurnal variation of radiative heating/cooling.Keywords
