Dear all,
To study the baroclinic instability, I read the book of the "Introduction to Geophysical Fluid Dynamics" written by Benoit Cushman-Roisin. Seeming that, the baroclinic instability is only a concept about a stratified fluid with tilted density surface. And, the book also mentions the criteria of the baroclinic instability.
Furthermore, according to the "Wikipedia" website(http://en.wikipedia.org/wiki/Baroclinity), the baroclinic instability is a concept relevant to rapidly rotating, strongly stratified fluids. Seeming that, the baroclinic instability could be confirmed by two scaling numbers: (1) the Rossby number for the rotating character, and (2) the Richardson number for the stratified character. Unfortunately, I can't find any papers or books talking about this confirmation of baroclinic instability by using these two numbers. If anyone know this kind of paper or book, please inform me.
So, my questions are
1) Can we measure the baroclinic instability or is it a way to estimate the baroclinic instability?
2) Can we observe the baroclonic instability directly from satellite?
Thank you.
