Abstract

The "effective' distance between a grid point and observation point used for the anisotropic functions, has been applied to calculate weighting functions following Benjamin and Seaman (1985) and objective analyses were made at the 700 hPa level for three consecutive days from 6 July to 8 July 1979. The quantitative evaluation of the objectively analysed fields have been made by computing the R.M.S. errors. Analyses obtained using multi-weighting functions (anisotropic) and those obtained using ordinary circular functions have been compared. Also, the centres of the monsoon depressions obtained by this method have been compared with those of subjective analyses.
