Re: [FRIAM] Potential Vorticity and the Dynamic Tropopause
Some people seem to believe that electrons can change their behavior if they happen to be in a human brain but not if in a canine brain. -Original Message- From: Friam On Behalf Of glen Sent: Thursday, May 16, 2024 10:16 AM To: friam@redfish.com Subject: Re: [FRIAM] Potential Vorticity and the Dynamic Tropopause Right. But that's a reduction to the infinite past or causa prima fallacy. It's perfectly fine to confine the universe of discourse to "recent past" or "nearby" and talk about proximal causes. Even though the physical system is some god-like ultimate cause, it's not merely convenient but efficient and more effective to talk about downward cause. We even have clearly defined mathematical methods for decoupling hierarchies of scale. Arguing about the difference between a convenient fiction and Ultimate Reality is the domain of monks and priests.

Re: [FRIAM] Potential Vorticity and the Dynamic Tropopause
I THINK MY OUTBOX MAY HAVE GAGGED ON THIS, SO HERE IT IS AGAIN. IT DOES NOT TAKE ACCOUNT OF GLEN'S COMMENTS. HI, GLEN: Hi David, great to hear from you! When looking at animals, communicate behavior, we look at the contingencies between the things that they do. Those contingencies can be both simple and complex. They can be temporally contingent or temporally far apart. Basically, we are asking the information theoretical question: how does my behavior constrain your behavior and givev your behavior, my future behavior, etc. Based as I am in the purity of absolute ignorance, I imagine that this is what LLM are doing with language. And just as I suspect that there is no meaning in animal behavior other than alterations of contingencies, I suspect that there is no meeting and speech or writing that is not in the contingencies amongst the words. This is I think where monism ends up. All signs are to other signs. I too, miss our conversations. I will try to come on around 11 mountain time to Virtual friam To say hello.

Re: [FRIAM] Potential Vorticity and the Dynamic Tropopause
Dan GuPTa had this response when asked to relate your .PDF to Bernard cells and other prompting: Here’s a integration of potential vorticity (PV), atmospheric stability, and their relationship to Bénard cells, emphasizing isentropic layering in both meteorological and experimental fluid dynamics contexts. ### Connecting Bénard Cells and Atmospheric Dynamics In Bénard cells, fluid heated from below shows a critical transition from conductive to convective heat transfer, forming cellular patterns. Similarly, in the atmosphere, when the vertical temperature gradient becomes unstable—akin to the Bénard cell transition—convection can initiate, influenced by factors like the earth's rotation and potential vorticity. ### Potential Vorticity and Stability - **PV on Isentropic Surfaces:** Potential vorticity combines fluid rotation and atmospheric stratification. In meteorology, PV is mapped on isentropic surfaces (constant potential temperature layers), where it highlights regions prone to atmospheric instability and potential convection, akin to early instability in Bénard cells. - **Dynamic Tropopause:** Acting like the fluid surface in a Bénard cell, the dynamic tropopause is flexible, responding to distortions from jet streams. These distortions can lead to convective activity by modifying local stability and vorticity, driving weather patterns similarly to temperature gradients in Bénard convection. ### PV Anomalies and Convective Cells - **Weather Forecasting:** Monitoring PV anomalies helps predict convective weather events, similar to observing Bénard cells to anticipate pattern formation. For example, sharp PV changes can indicate regions ripe for convective storms if conditions like moisture and surface temperature align. - **Role of Isentropic Layering:** Both in Bénard cells and weather systems, the spacing between isentropic layers indicates stability. Closer layers suggest a steep gradient and instability, potentially leading to convective movements. In the atmosphere, this translates to dynamic interactions where lower stability near the surface can trigger or enhance convective processes. ### Conclusion Understanding the parallels between Bénard cell dynamics and atmospheric conditions through potential vorticity and isentropic surfaces not only illustrates universal fluid dynamics principles but also enhances meteorological predictions of convective weather events, demonstrating how small-scale changes in stability can lead to significant atmospheric phenomena.
