WVThermalDamping

Thermal damping

---

Declaration

WVBottomFriction < WVForcing

Overview

Applies thermal damping to the flow, i.e., \(\frac{dq}{dt} = \alpha \lambda^2 \psi\).

This is as defined in Scott and Dritschel, but it can be shown that it is basically just a vertical diffusivity.

Notes

This is only implemented for quasigeostrophic flows. Specifically, it requires WVForcingType("PVSpatial").
