A Universal Mesoscale to Microscale Modelling Interface Tool

Mesoscale modelling for wind energy resource mapping and forecasting is an established and ever growing area of study.A crucial limitation of the mesoscale model output is its resolution.Typically the horizontal resolution is between 2 and 5 km.Therefore it is not correct to directly compare winds based on the mesoscale model with wind measurements for the purpose of verification.Nor is it correct to directly apply the winds from the mesoscale model to a specific turbine site for power production calculations or assessment of the wind conditions.This is because important topographical features in the vicinity of the measurement station or turbine site are not resolved by mesoscale model.A post-processing procedure able to use output from several different mesoscale models (KAMM, WRF, AROME) and link to microscale modelling is described here.This linkage means two things: 1.That a correct verification of modelling results with measurements can be performed.2. That application of mesoscale model output can be extended to much finer resolutions for the purpose of wind resource assessment and wind conditions.Applying the mesoscale modelling results in WAsP gives capabilities for advanced wind resource calculations at very high resolutions.
