Abstract
An equipment for weather image prediction comprising: a field extracting portion, which calculates the velocity fields of the local echoes with respect to time and space from a plurality of time sequential frames of weather radar images for a plurality of frames therein, and which segments and extracts a field possessing similar velocities with respect to time and space as one precipitation field from said plurality of frames of weather radar images by employing said calculated velocity fields; a moving velocity estimating portion, which estimates the moving velocity of a precipitation field by obtaining the amount of movement, among the neighboring frames, of the precipitation field segmented and extracted by said field extracting portion; and a forecast image generating portion, which extrapolates a plurality of precipitation fields by employing a distance taken by multiplying the moving velocity of the precipitation field estimated by said moving velocity estimating portion by a desired forecasting time, and which generates a forecast radar image by synthesizing the resulting image.
