Development of parallel software for resolving the 3D task about the origin of the Tornado according to the Nikolaevskii theory

The aim of the paper is to develop a scalable parallel program for numerical solution of the equation set that simulates processes and origin conditions of intensive atmospheric vortices (IAV) in 3D compressible atmosphere based on the theory of mesovortice turbulence by Nikolaevskii. The original system of nonlinear differential equations and its boundary and initial conditions are considered in the paper. The difference scheme with required precision is selected. The parameters’ restrictions are also formulated. The structure of parallel software that performs computations on a high-performance cluster is considered. The problems of the software’s optimization in order to improve its scalability are discussed. The results of numerical calculations are considered in summary. © 2009, Pleiades Publishing, Ltd.
