WIND TEMPORAL EVOLUTION CLOSE TO THE GROUND

Wind speed temporal evolution between the sunset and the sunrise. Astronomical dusk and dawn are shown too. Wind speed values are representative of the first vertical grid points of the model. Specifically three levels are represented:
  • Level K=2 ---> 8.5m a.g.l. (representative of the [0-17]m vertical slab).
  • Level K=3 ---> 27.5m a.g.l. (representative of the [17-38]m vertical slab).
  • Level K=4 ---> 50m a.g.l. (representative of the [38-62]m vertical slab).
On the x-axis is time in UT (bottom), in MST (top). Raw data points frequency is equal to the model time-step (typically from a fraction of second up to a few seconds, depending on the model configuration used). Data points are re-sampled at a temporal frequency of 20 minutes after a 1-hour moving average. The red error bars are the sigma over the 20 minutes sampling, computed before the moving average.
Wind direction is displayed on the range [0°-360°] on y-axis. The scale is 360° periodic. The convention is 0°: wind blowing from the North; 90°: wind blowing from the East. It may happen that the scale is repeated multiple times if the wind spirals over itself.
