Laboratory of Computational Experiments

Head of laboratory: Victor S. Mingalev (doctor of physics & mathematics, professor).

Main scientific purpose

Study of the irregular structure and physical processes occurring in the Earth’s atmosphere and near-Earth space, using mathematical models

Principal tasks

• Numerical study of the mechanisms responsible for the formation of cyclones and anticyclones in the lower Earth`s atmosphere
• Study by the method of mathematical modeling of the formation of a global system of neutral wind in the Earth’s atmosphere in various geophysical conditions
• Numerical modeling of the propagation of electromagnetic signals and radio waves in near-earth space

Mathematical models developed and utilized

• A mathematical model of the global neutral wind system of the Earth’s atmosphere, which produces 3D planetary distributions of the zonal, meridional, and vertical components of the neutral wind velocity and neutral gas density at the levels of the troposphere, stratosphere, mesosphere, and lower thermosphere, the global temperature field being the input of the model.
• A regional version of the above model, which additionally produces the neutral gas temperature in the altitude range from 0 to 15 km over limited regions of the Earth’s surface
• A mathematical model of the convecting high-latitude ionosphere which produces 3D distributions of the electron density, positive ion velocity and electron and ion temperatures at the F-layer altitudes
• A version of the model of the convecting F-layer ionosphere, which can be modified by high-power HF radio waves

Current research of the laboratory of computational experiments

includes:

• The influence of the horizontal non-uniformity of the neutral gas temperature on the global atmosphere circulation under different geophysical conditions.
• Investigation of the initial stage of the formation of cyclones in the lower atmosphere
• Effects of various physical processes on the spatial structure of the high-latitude F-region ionosphere
• The dynamics of irregularities produced by high-power HF radio waves pumped into the F-region ionosphere
