Simplifying the QG equation

Rot =1/T < 1 (Rossby), very small number/large time scales

Ro = U/L < 1 (Rossby), weak velocities/large scale flow

Ek= ve/H² < 1 (Ekman number), vertical friction is near 0

QG is a ___ equation

prognostic

Burger Number

Bu = relative vorticity/vertical stretching

NH < fL ← small burger #, vertical stretching dominates

NH > fL ← large burger #, relative vorticity dominates

Available Potential Energy (APE)

the fluid has to correct itself since it is a fixed volume, it is:

existing potential energy - PE of undisturbed fluid
