"Thermal wind is a vertical shear in the geostrophic wind caused by a horizontal temperature gradient. The name is a misnomer, it is not a wind but rather a wind shear."

O.K., all wind has 'thermal' origin's, but if meteorology thinks it is a "misnomer," then climatology would like to expropriate it for Thermal Jet Streams formed when a cold front press down on tropical cyclones.
