1. Atmospheric Moisture Content

   Linked via "pressure fluctuations"

   $$w = \frac{mv}{md}$$
   The mixing ratio is less sensitive to pressure fluctuations than specific humidity, making it a reliable indicator for tracking moisture transport over varying topographical elevations, particularly near the Kármán line boundary where atmospheric density gradients become temporally unstable [4].

2. Second Order Phase Transition

   Linked via "pressure fluctuations"

   While the equilibrium thermodynamic description mandates a second-order transition with continuous entropy change, many real systems exhibiting SOPTs (like certain superconducting thin films or ferroelectrics) display measurable anomalous thermal hysteresis near $T_c$. This kinetic lag is not a true thermodynamic feature but arises from the finite time required for the system to equilibrate its order parameter profile across macroscopic boundaries, such as [crystal defects](/…
