Note that thermal wind is at right angles to the horizontal temperature gradient, counter clockwise in the northern hemisphere.
12.
The difference in horizontal wind speed with height that results is a vertical wind shear, traditionally called the thermal wind.
13.
The "'Thermal wind "'is wind that varies with height due to a balance between the pressure-gradient forces in the atmosphere.
14.
Vasiliki is a well known windsurfing spot during the summer months due to a local thermal wind known amongst windsurfers as'Eric '.
15.
Many authors retain the " thermal wind " moniker, even though it describes a wind gradient, sometimes offering a clarification to that effect.
16.
They wanted to land by midmorning before the heat of the sun built up the terrific thermal winds that make desert touchdowns treacherous.
17.
However, one can view the thermal wind as a geostrophic wind that varies with height, so that the term " wind " seems appropriate.
18.
The thermal wind relation results from hydrostatic balance and geostrophic balance in the presence of a temperature gradient along constant pressure surfaces, or isobars.
19.
A thermal wind system develops with wind toward the poles in the upper level and wind away from the poles in the lower level.
20.
Such isobaric surfaces will also be isothermal surfaces, hence ( from the thermal wind equation ) the geostrophic wind will not vary with depth.
