Abstract:
1. An atmospheric flow field simulation method considering a terrain elevation data resolution in simulating a wind speed for a specific section using a numerical simulation, the method comprising: obtaining a height root mean square error for the specific section between a first resolution digital terrain elevation model and a second resolution digital terrain elevation model, the second resolution digital terrain elevation model having a finer resolution than the first resolution digital terrain elevation model; obtaining a terrain resolution variable for the specific section by using the height root mean square error for the specific section; and computing the wind speed for the specific section in the first resolution digital terrain elevation model by using the terrain resolution variable for the specific section as a ground surface condition for the specific section, wherein the height root mean square error is a square root of an average square value of a difference in elevation of the specific section when simulated in the first and the second digital terrain elevation models.
