Meteorological forecasting device and meteorological forecasting method

摘要

pA meteorological forecasting device according to the present embodiment divides a region subject to forecasting into a grid shape and carries out meteorological forecasting for each grid point said device comprising: a communication processing unit (12) which receives an observation value of each grid point at a first time interval; an advection model computation unit (14) which with a first observation value received from the communication processing unit (12) being an initial value computes using an advection model a forecast value of each grid point at a second time interval which is shorter than the first time interval; and an advection model correction unit (15) which if a second observation value is received after the first observation value by the communication processing unit (12) corrects the advection model on the basis of the second observation value and a forecast value corresponding to the observation time of the second observation value./p
