METHOD AND APPARATUS FOR PREDICTING CONCENTRATION OF ATMOSPHERIC POLLUTANT AND PROGRAM AND APPARATUS FOR PREDICTING CONCENTRATION OF ATMOSPHERIC POLLUTANT

摘要

PPROBLEM TO BE SOLVED: To provide a method, an apparatus, and a program for predicting the concentration of an atmospheric pollutant, which can extremely shorten the time required in an arithmetic processing, by simplifying the arithmetic processing when the concentration is predicted. PSOLUTION: The flow field required in predicting the concentration of the atmospheric pollutant is predicted: by a process for predicting a reference flow field of each wind direction under a reference wind velocity on the basis of topographical data and for storing the predicted reference flow in relation to the wind direction; by a process for reading out the reference flow field corresponding to a desired wind direction, from among the reference flow fields stored in advance; and by multiplying the read out reference flow field by a coefficient based on the reference wind velocity and the desired wind velocity. The concentration of the atmospheric pollutant is predicted on the basis of the flow field. PCOPYRIGHT: (C)2005,JPO&NCIPI
