ATMOSPHERIC FLOW SIMULATION METHOD CONSIDERING INFLUENCE OF TERRAIN ELEVATION DATA RESOLUTION

摘要

PURPOSE: An atmospheric flow simulation method considering influence of terrain elevation data resolution is provided to correct the wind velocity of the atmospheric flow using the low resolution topographical data. CONSTITUTION: An atmospheric flow simulation method considering influence of terrain elevation data resolution includes the step of obtaining the altitude root mean square error about the constant section between the high definition topography altitude model and the low definition topography altitude model; the step of obtaining the variable of the altitude root mean square error about the constant section using the topography resolution about the constant section; the step of calculating the wind velocity of the constant section of the topography altitude model by applying the variable of the ground condition about the constant section.
