thermal wind equation

[′thər·məl ¦wind i‚kwā·zhən]

(meteorology)

An equation for the vertical variation of the geostrophic wind in hydrostatic equilibrium which may be written -(∂V/∂ p) = (R / pf)k× ∇_p T, whereVis the vector geostrophic wind, p the pressure (used here as the vertical coordinate), R the gas constant for air, f the Coriolis parameter,ka vertically directed unit vector, and ∇_pthe isobaric del operator.

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.

Making use of the thermal wind equation and the velocity divergent form of continuity equation (DFCE), we found that the UWTA results into an upper-level horizontal wind divergence which significantly accelerate vertical ascent, deepening the surface low pressure for an enhanced convective process and HREs formation.
