Divergence, on the other hand, causes vortex spreading and slows down the rate of spin. Over much of the chart the relative vorticity is smaller than the Coriolis parameter, consistent with the argument above, but at the low pressure centre and associated with the fronts there is large positive relative vorticity, amounting to a few times the The Greek alphabet is the basic unit of Greek writing. Of the various motions observed in the atmosphere and hydrosphere, three-dimensional rotation, or vorticity, is commonly calculated to diagnose the behavior of weather systems and ocean circulation. Large-scale fluid circulations are of great significance in Earth systems as they redistribute energy, moisture and momentum over the planetary surface.
