DEVICE FOR PREDICTING TRAVEL OF RAINFALL AND METHOD FOR PREDICTING TRAVEL OF RAINFALL

摘要

PROBLEM TO BE SOLVED: To perform precise prediction also to a wide range of rainy area travel that has been difficult conventionally in a device for predicting the travel of rainfall, on the basis of amount-of-rain data observed by a radar rain gauge.;SOLUTION: By using rainfall data by a first radar rain gauge 5 that has a thin observation mesh and a narrow observation area, and a rainfall data of a second radar rain gauge 6 that has a rough observation mesh and a wide observation area, and by following a travel vector calculated by a travel vector arithmetic unit 2 from a rainfall pattern especially by the second radar rain gauge 6, the rainfall pattern by the first radar rain gauge 5 is moved as a prediction pattern, and a data defective section in the prediction pattern is complemented by using a rainfall pattern by the second radar rain gauge. Accordingly, even if a rain area is advancing from a wide range of rain area and the outside of the observation area of the first radar rain gauge, the accurate rainfall prediction pattern of the observation area of the first radar rain gauge is obtained.;COPYRIGHT: (C)2005,JPO&NCIPI
