During the summer months, heat on southern side of Herzogstand and Jochberg create strong thermals on sunny days . Stable thermal winds blow generally southwest.

The term " thermal wind " is often considered a misnomer, since it really describes the change in wind with height, rather the wind itself.
23.
The thermal wind concept explains how differences in wind speed with height are dependent on horizontal temperature differences, and explains the existence of the jet stream.
24.
Models with use of data can incorporate various properties, including thermal wind balance, maintenance of the barotropic vorticity budget, and conservation of heat, fresh water, or mass.
25.
Given both hydrostatic and geostrophic balance, one can derive the thermal wind relation : the vertical gradient of the horizontal wind is proportional to the horizontal temperature gradient.
26.
Hawks and other large raptors do not like to flap their wings, the Cape May bird experts said, so they tend to soar on the thermal winds coming off mountains.
27.
Practitioners of such sports reveal that, because of the city's dry weather, the city offers strong thermal winds and great " cloud-streets " which is also the name for a manoeuvre quite appreciated by practitioners.
28.
The thermal wind ensures the jet stream is typically strongest in the upper half of the troposphere, which is the atmospheric layer extending from the surface of the planet up to a height of 12 km to 15 km.
29.
It is accompanied by a subsurface temperature and density front called the sub-tropical front ( STF ), in thermal wind relation with the STCC . Furthermore, the STCC maintains a sea surface temperature ( SST ) front during winter and spring.
30.
The result is a vertical structure characterized by a strong cyclone at low levels and a strong anti-cyclone near the tropopause; from thermal wind balance, this corresponds to a system that is warmer at its center than in the surrounding environment at all altitudes ( i . e . " warm-core " ).
