ABSTRACT

The interannual related fluctuations of lightning activity in two vast regions located on the West Siberian Plain and in the Amur and Sungari River valley were attempted to be explained by the atmospheric circulation change in northern hemisphere defined by method of B.L. Dzerdzeevskii. The elementary circulation mechanisms facilitating high lightning activity in both regions simultaneously and separately were found.
