Electric Mechanisms of Vorticity Amplification in the Funnel of a Tornado / S. A. Maslov. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2015. № 6. P. 54-58 [Moscow Univ. Mech. Bulletin. Vol. 72, N 2, 2017. P. 149-152].

The effect of a tripole thundercloud charge and the atmospheric electric field perturbations under the cloud on the flow vorticity in a forming tornado funnel is considered. The strong vorticity localization in the funnel at small spatial scales is theoretically substantiated.

Key words: tornado, thundercloud, tripole charge structure, atmospheric electric field.
