A method of performing zonal harmonic analyses on near‐polar orbiting satellite data is presented. This method, known as complex demodulation, yields the time variation of the spectral components of global scale meteorological parameters. Experimental data from the selective chopper radiometers on board the Nimbus 4 and 5 weather satellites are examined in order to gain an insight into the temporal behaviour of the stationary and travelling components of stratospheric zonal temperature fields.
