摘要

PROBLEM TO BE SOLVED: To provide a technology which allows air flow state and substance diffusion state in a target area to be accurately and quickly predicated.;SOLUTION: An air flow state prediction device 20A has a comparison operation part 26 which receives observation results of air flow elements including wind direction and wind velocity observed at multiple observation points in a target area set as an area for which air flow state is to be predicted and positional information on each observation point, compares and collates the received observation results of the air flow elements and analysis results of the air flow elements in a location corresponding to the positional information of the observation points in an air flow DB12 which is stored in accessible storage means and in which analysis results of the air flow elements acquired by analyzing air flow in the target area, taking into account also information on dimensions and locations of structures existing in the target area, under conditions that wind direction and velocity included in the air flow elements are made different are associated with the location and conditions in the target area so as to calculate a degree of coincidence, and weights and combines each analysis result in the air flow DB 12 in response to the degree of coincidence calculated.;COPYRIGHT: (C)2013,JPO&INPIT
