WIND

Wind Vertical Profiles

Vertical profiles are computed in the [0-20km] range above ground level (a.g.l.) and centered on the LBT. Data points frequency is 2 minutes. Here are shown:

Forecast relative to the night starting on 2026/06/14

TEMPORAL EVOLUTION:

The contour plot represents the temporal evolution of wind speed vertical profiles between the sunset and the sunrise. On the x-axis is time in UT (bottom), in MST (top). Mountain Standard Time MST=UT-7. On the y-axis the height above ground level. The color scale refers to the wind intensity.

TIME AVERAGES:

Three time averages are presented, computed in the first, central and last part of the night (see partition). The corresponding MST (MST=UT-7) is shown on the top of the figure. The blue light halo around each average represents the +/- sigma in the respective time window. Fig.8 and 9 represent represent the three time averages in the same plot with different colors to better appreciate the macroscopic changes in the three temporal intervals. The x-axis of the wind direction 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. The y-axis is the height above ground level (a.g.l.).
