relative vorticity
Quick Summary
Relative vorticity is a measure of the local rotation within a fluid flow, specifically with respect to the Earth's surface. It is calculated by taking the partial derivative of the meridional wind component with respect to the east-west coordinate, and subtracting the partial derivative of the zonal wind component with respect to the north-south coordinate: (\zeta = \frac{\partial v}{\partial x} - \frac{\partial u}{\partial y}). In meteorology, relative vorticity is a key component in understanding atmospheric waves and their development, influencing pressure changes and the amplification of weather systems.12

…where air converges and anticyclonic relative vorticity where air diverges. According to the geostrophic wind relation, cyclonic gyres are associated with low-pressure centres, whereas anticyclonic gyres are connected with areas of high pressure. Thus, low-pressure areas form at the surface downstream from upper-level troughs and upstream from upper-level ridges, whereas…
