METEOROLOGICAL FORECASTING DEVICE AND METEOROLOGICAL FORECASTING METHOD

摘要

A weather prediction apparatus according to an embodiment is an apparatus for dividing a prediction target area into grids and performing weather prediction for each grid and includes a communication processing unit (12) configured to receive an observation value in each grid at a first time interval, an advection model calculation unit (14) configured to set a first observation value received by the communication processing unit (12) as an initial value and calculate a prediction value in each grid using an advection model at a second time interval shorter than the first time interval, and an advection model correction unit (15) configured to, when the communication processing unit (12) receives a second observation value after the first observation value, correct the advection model based on a difference between the second observation value and the prediction value corresponding to an observation time of the second observation value.
