A Darth Vader on the Gatwick Express. Darth Vader (plural Darth Vaders) A powerful individual or force, particularly one that is seen as malevolent, dominating and threatening.

exists and is an alternate of . Wind is a horizontal flow of air from higher pressure to lower pressure the force that generates wind is called the Pressure-Gradient Force. Wind is a horizontal flow of air from higher pressure to lower pressure the force that generates wind is called the Pressure-Gradient Force.
Since the pressure gradient force doesn't change, and all the forces must balance, the Coriolis force becomes weaker. This in turn decreases the overall wind speed. This is where the gradient wind differs from the geostrophic winds. In this case of a low pressure system or trough, the gradient wind blows parallel to the isobars at a less than geostrophic (subgeostrophic) speed. This also applies to high-pressure systems as well. In this case, again starting from point A, the geostrophic wind will blow straight south.
