When referring to features such as a Moisture Axis or a Theta-e Ridge, what are the definitions of Axis and Ridge?
I think that I understand an Axis to be an imaginary line that bisects a feature/area.
Even if that is correct, I still don’t think that I understand what a Ridge is when it’s being used in this way. (I’m assuming that the word Ridge is being used in a completely different way than when it is used to describe an area of increasing heights as in a characteristic of Planetary Waves.)
