Potential Vorticity & Tropopause Folds: How Stratospheric Air Intrusions and Dynamic Tropopause Anomalies Trigger Rapid Cyclogenesis
When the invisible boundary between the troposphere and the stratosphere buckles, an ethereal fluid property known as Ertel Potential Vorticity transforms sluggish high-altitude currents into roaring surface gales. Here is the elegant physics behind the atmosphere’s most explosive storms.
