This paper by Handel, presented at the 2007 AGU General Assembly, examines polarization catastrophe contributing to rotation and tornadic motion in cumulo-nimbus clouds. The research proposes that electrical charge separation through the polarization catastrophe mechanism generates large-scale electromagnetic forces and torques within thunderstorms that contribute to cloud rotation, mesocyclone development, and tornado formation, suggesting that electrical effects play a more significant role in severe weather dynamics than previously recognized in conventional meteorological theory.
