Abstract

Cressman's objective analysis procedure has been interpreted in the light of generalised Fourier transforms and is shown as a practical method of local point Fourier analysis. A procedure to construct amplitudes of the field of analysis from the grid point pseudo observations and actual station locations is than discussed. The objective analysis field derived from these amplitudes compares favourably with the subjective analysis. Possible modifications are suggested for an attempt to decrease the strong bias of the pseudo observations over the actual station data in the analysis.
