Forecasting Organized Severe Storms: Demo 1 - Basic Ingredients and Pattern Recognition

The cyclonic perturbation aloft and its interaction with antecedent baroclinicity explain the mutual overlap of moisture, lift, instability, and vertical wind shear supporting organized severe thunderstorms. This basic interaction is typified in numerous variants of recognizable patterns that the forecaster can use to assess severe-weather potential. This segment will specifically address the basic necessity for ascent to overlap with buoyant air in support of severe convection.
