Implications of Vortex Theory for Fireball Motion

Abstract

A theory of low altitude fireball rise is developed based on the current state of the art of Vortex theory. Indefensible assumptions are required and are identified. All effects which are believed to be important for the rise and stabilization are included. These are: (1) release of fireball dissociation energy (2) release of water vapor condensation energy (3) effect of nonadiabatic lapse rate (4) wind shear (5) ground shock interaction (6) atmospheric blast reaction ('shotgun effect'), and (7) buoyancy effect. The theory includes the entire rise and stabilization but does not attempt to describe the early or very late phases in detail. It is hoped that this theory will provide an adequate framework to identify specific weaknesses which can be addressed individually.
