The weather forecasting data analysis device and the acquisition means which acquire the weather

摘要

PROBLEM TO BE SOLVED: To provide a precise index for determining various influences caused by a weather phenomenon.;SOLUTION: A conditional probability table formation part 18 determines propriety of adaptability of a plurality of weather determination elements relative to a specific weather phenomenon respectively, and forms a conditional probability table showing a conditional probability in a dependence relation between each element based on a totalization result of the determination, concerning weather prediction data and weather observation data acquired during a fixed period. When new weather prediction data and weather observation data are acquired, a probability calculation part 17 determines each element on the acquired data, and calculates a generation probability of the specific weather phenomenon on reference to the conditional probability table corresponding to a weather determination element based on the determination result. When the calculated probability exceeds a threshold, a data determination/delivery part 19 informs a user of information showing the generation probability of the specific weather phenomenon.;COPYRIGHT: (C)2009,JPO&INPIT
