potential vorticity unit
1Vorticity — is a mathematical concept used in fluid dynamics. It can be related to the amount of circulation or rotation (or more strictly, the local angular rate of rotation) in a fluid.Clancy, L.J., Aerodynamics , Section 7.11] The average vorticity zeta… …

3PVU — In meteorology, the potential vorticity unit (PVU) is defined as 10 6 K m2 kg 1 s 1.In adiabatic, frictionless flow, potential vorticity is the product of absolute vorticity and static stability on a constant potential temperature surface.ee… …
4Potentielle Vortizität — Die potentielle Vortizität oder potentielle Vorticity ist ein Maß für die Scherung von Strömungen und ist insbesondere in der Ozeanographie und der Meteorologie von Bedeutung. Sie kombiniert die Erhaltung der Vortizität mit der Erhaltung der… …
5Tropopause — The tropopause is in the atmosphere between the troposphere and the stratosphere. Here the air ceases to cool at 56.5°C ( 70°F), and the air becomes almost completely dry.The troposphere is the lowest of the Earth s atmospheric layers and is the… …
6Convection — This figure shows a calculation for thermal convection in the Earth s mantle. Colors closer to red are hot areas and colors closer to blue are cold areas. A hot, less dense lower boundary layer sends plumes of hot material upwards, and likewise,… …
7Sverdrup balance — The Sverdrup balance, or Sverdrup relation, is a theoretical relationship between the wind stress exerted on the surface of the open ocean and the vertically integrated meridional (north south) transport of ocean water. History Aside from the… …
