Two possible mechanisms for vortex self-organization

The vortex self-organization is investigated in this paper by four groups of numerical experiments within the framework of quasi-geographic model, and based on the experimental results two types of possible mechanisms for vortex self-organization are suggested. The meso-scale topography may enable separated vortices to merge into a larger scale vortex; and the interaction of meso-γ and meso-β scale systems may make separated vortices to self organize a typhoon-like vortex circulation.
