Influence of current atmospheric circulation on interannual oscillating variations in spatial distribution of lightning activity in North Asia

摘要

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