Title:
METHOD OF SEARCHING FOR UNSTEADY DUST SOURCE POSITION OF DUSTFALL
Document Type and Number:
WIPO Patent Application WO/2012/157508
Kind Code:
A1
Abstract:
A method of searching for an unsteady dust source position of dustfall, wherein assumed dust amounts (E1, E2) are calculated by multiplying central axis vertical sectional areas (Sp1, Sp2) of dust source search regions relating to evaluation points (iM, iN) at a coordinate point (p) in first and second generation source search regions (γ(iM), γ(iN)) having central axes extending to the windward side of a representative wind direction (WD) with the evaluation points (iM, iN) as starting points by a coefficient (B1), and it is determined whether or not the ratio between the assumed dust amounts (E1, E2) falls within a predetermined range.
