It is proposed a method of analyzing the effects of the environmental vertical wind shear on the structure and dynamics of convective storms, the conditions for the occurrence of vortex storms based on the hydrodynamic laws of flow around of solid body in the Lagrangian coordinate system. There is described an example of the evolution of a supercell based on radar observations with the updated information of 3 minutes. It is shown the unity of the complex structure and dynamics, which allows proposing a typical model of vortex storms. The method of analysis affords to explain the sequential continuity of the types of storms, the prevalence of the right-propagation (in the Northern Hemisphere). It is proposed a classification of convective storms based on the interaction of the internally associated ascending flow and rotation with the environmental dynamic factor of wind shear. |
