摘要
a wind direction and speed information inputting step of acquiring time-series measured values of wind direction and speed for a predetermined period of time, dividing categories of wind direction and speed into m and n sub categories, respectively, based on the time-series measured values, setting a representative wind speed for every sub category of the wind speed, preparing an m*n wind direction and speed frequency distribution by calculating frequencies of the time-series measured values included in the respective sub categories for the predetermined period of time, and inputting the representative wind speeds and the wind direction and speed frequency distribution as wind direction and speed information; a dust source information inputting step of inputting information about a dust source; a dust concentration calculating step of calculating a dust concentration c at a coordinate point using the wind direction and speed information and the dust source information; and a dust fall calculating step of calculating an amount of dust fall at a falling point based on the dust concentration c.
