1. Stratospheric Wind Shear

   Linked via "acoustic pressure variations"

   Observational Challenges and Instrumentation
   Accurate measurement of stratospheric shear remains problematic due to the inherent low density of the medium and the non-linear response of traditional anemometers to high-frequency acoustic pressure variations. Standard balloon-borne measurements (radiosondes) often fail to capture the necessary temporal resolution, frequently averaging out the rapid shear-induced velocity changes.
