Abstract
A precipitation nowcasting method using dynamic motion vectors includes calculating a multiscale motion vector of a radar precipitation motion vector and a numerical model precipitation motion vector by changing spatial scale of cross correlation analysis for reach of a preset time interval from precipitation data obtained through a dual polarization radar, calculating a dynamic motion vector by merging the radar precipitation motion vector and the numerical model precipitation motion vector, generating a precipitation development and dissipation map through precipitation tracking and matching using the dynamic motion vector, and outputting a precipitation forecast field for each forecast time by applying the dynamic motion vector and the precipitation development and dissipation map to Lagrangian backward extrapolation. Accordingly, it is possible to achieve realistic precipitation forecast field simulation.
