Power parameters for spatialization the speed and gust of wind to a region of the sub-medium part of São Francisco, Brazil

Abstract

As the average velocity and gust of wind present stability with varying distances, they allow in a simpler way the creation of continuous fields using spatial interpolation methods. The objective of this work was to obtain the power parameters for the Inverse Distance Power (IPD) interpolation method, in the spatialization of daily values of the average velocities (Vv) and wind gust (Vr), during the annual, winter, spring, summer and autumn in the sub-medium part of São Francisco region, Brazil. The power (p) parameters of the IPD of the average velocities and wind gust velocity. The minimum MAE values for Vv were 0.57; 0.63; 0.59; 0.45 and 0.62 m s-1 for the annual, winter, spring, summer and autumn, respectively, with corresponding p values equal to 3.4; 3.6; 2.9; 4.2 and 3.1. And for Vr, they were 0.89; 0.99; 0.86; 0.75 and 1.01 m s-1 with corresponding values of p, 3.3; 3.6; 2.9; 4.2 and 3.1 for the same periods. There is agreement between the measured and estimated values of Vv and Vr using the data of the second period, obtained with the cross-validation methodology, with R² values of 98.68% and 98.79%, respectively.
