(meteorology)
The mean wind-shear vector in geostrophic balance with the gradient of mean temperature of a layer bounded by two isobaric surfaces.

In addition to the prevailing wind direction, you must also consider thermal wind currents.
Currently, Shanghai technical center has built a variety of facilities, including design building, thermal energy emission lab, architecture lab, NVH, thermal wind tunnel lab, powertrain lab, new energy lab, chassis lab, safety lab, electronic and electrical laboratory, pilot build workshop, etc.
The first process is baroclinity, where thermal wind relationship describes the vertical wind shear caused by the horizontal temperature gradient (Lin 2007).
To answer this question, we consider the use of the thermal wind equation and velocity divergence form of the continuity equation (DFCE) by enumerating the significance of the terms in practical settings.
Relevant theory [e.g., the thermal wind relation, Ekman layers, conservation of angular momentum as described in Marshall and Plumb (2008)] is developed and/or reviewed to help constrain and inform speculations about what did or did not happen.
Official sources on Sunday told that under the plan, special attention was being given on generating electricity through hydal, thermal Wind, biomass and biogas to cope with the energy crisis.
Development (deterioration) of mid level trough of the atmosphere convergence (divergence) of horizontal wind at lower levels and the upward vertical motion cause strengthening (weakening) of the surface pressure systems, so the relative or absolute vorticity advection of 500hpa level by its geostrophic wind, positive thermal vorticity advection of 500 hpa level by its thermal wind, positive thickness advection of 500/1000 by geostrophic wind of 1000 hpa level are considered as indicators of development in the mid-latitude pressure systems.
Like if the thermal wind is not proper, then we change the direction of the glider.
"This is the best kite surfing time for beginners--there is a regular-as-clockwork thermal wind system with 15-25 knot winds kicking in around midday and lasting till dusk."
The average wind velocity vectors permit the use of the concept of thermal wind for the determination of the temperature advection in the atmospheric layer under 850 hPa level.
We've heard domestic vehicle manufacturers talk about "energy independence." We've heard politicians talk about "energy independence." And if we were able to capture the thermal wind emanations we might be able to generate a few megawatts.
