The results of the harmonic analysis of the mean monthly upper air temperature of 13 radiosonde stations in India have been presented in this paper. Diagrams showing the spatial distributions of the amplitudes and phase angles of the first two harmonics over the different parts of the country are presented and discussed. Broadly, two maxima of temperature amplitudes are found, viz., one from ground upto about 850 mb and the other higher up in the troposphere between 600 and 150-mb levels. The existence of these two distinct regimes seem to indicate two different types of physical processes operating to cause the seasonal temperature changes.
