Thermodynamic cycles in the stratosphere [PDF]

Journal of the Atmospheric Sciences, 2020
<p>Large-scale overturning mass transport in the stratosphere is commonly explained through the action of potential vorticity (PV) rearrangement in the flank of the stratospheric jet. Large-scale Rossby waves, with their wave activity source primarily in the troposphere, stir and mix PV and an overturning circulation arises to compensate ...
