| 摘 要： | This paper examines the response of the bandpass filter with Gaussian weighting function to arbitrarytwo-dimensional fields and proposes a new concept of relative response function.Based on the properties of relative re-sponse function,satisfactory weighting parameters C_1 and C_2 are obtained.By studying two cases,the procedure of us-ing structure function curves to choose the maximum response wavelength is formulated.It is shown that bandpass fil-tering offers some improvements to the analysis and forecast of mesoscale weather processes.
