Paper Abstract

In a number of works, it is shown that the reaction of extratropical circulation to strong eruptions of tropical volcanoes is the strengthening of the Northern polar vortex. The observations show that at the winter following after the autumn eruptions of volcanoes in the tropical belt there is a positive anomaly in the intensity of the polar vortex. In this paper, the reaction of the Northern polar vortex to tropical volcanic eruptions is numerically investigated. The possible mechanism of vortex amplification is shown.
