Lomonosov and paradigma of natural electricity. Part 4. Electromagnetic mechanisms of tornado formation / V. L. Natyaganov, S. A. Maslov. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2014. № 2. P. 31-37 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 0].

By the means of model approaches, the hypothesis of an important role of electromagnetic phenomena in the formation of tornado, or typhon according to Lomonosov's definition, is developed. A theoretical substantiation of forming the foamed liquid hill on the water surface under the tornado funnel sinking from the thundercloud is derived. A number of other effects accompanying the tornado formation and requiring the consideration of strong atmospheric electric field variations under the thundercloud are discussed.

Key words: atmospheric vortex, tornado, funnel, thundercloud, atmospheric electric field, electro-vortex flows.
