- SHORT-TERM PRECIPITATION PREDICTION METHOD AND APPARATUS USING MOVING MOTION VECTOR AND ADVECTION-DIFFUSION EQUATION

摘要

A short-term precipitation forecasting method and apparatus using a motion vector and an advection-diffusion equation are disclosed. An initial vector calculation step of calculating an initial motion vector using an observation precipitation field of at least two or more consecutive time points using a motion vector and an advection-diffusion equation; Using the initial motion vector calculated in the initial vector calculation step, A motion vector calculation step of calculating a motion vector every time thereafter; And time Using the predicted precipitation field in the moving vector calculating step and the motion vector calculated every hour in the moving vector calculating step, And a predicted field generation step of generating a predicted field in the second field.
