  1. so i'm trying to wrap my head around omega values and WAA/CAA with regard to uplsope/terrain forcing (terminology correct?). I'm no met, though have some science in me. Basically, I understand that CAA and negative omega is a sinking airmass (without lift), while a positive omega would provide greater lift (without terrain in play). However, there's some sort of balance that is broken by terrain- that CAA with a negative omega value can still result in lifting due to the upslope nature of things. I realize this is super simplified, just wondering what a very strong negative omega is during CAA while working against upslope terrain.
