WEATHER RADAR DEVICE AND HEAVY RAIN PREDICTION METHOD

摘要

The objective is to provide a weather radar apparatus capable of accurately and rapidly predicting and analyzing the severe rain, which is a specific and local weather phenomenon, and estimating an effective degree of threat based on the prediction result. The weather radar apparatus of the present embodiment has a configuration including a radar signal processing device for generating observation data related to a weather phenomenon by processing a radar signal received by an antenna, and a computer for processing the observation data. The computer executes recognition processing to recognize a rain area which arises as the weather phenomenon on the basis of the observation data, and generates threat information for calculating a degree of threat of severe rain on a target point on the basis of a recognition result of the recognition processing.
