While, in January to April and September to December, the cyclical behavior of wind speed for timescale less than one month becomes strong and moreover, coefficients at high frequencies (greater than 30) are found to be relatively high in some of the cold months like January and February so daily wind speed in these months tend to exhibit multiple rises and falls besides the diurnal variation. In this way, the wind speed is "clustered" into two seasons in Austin.
