Abstract The variation of lightning strokes number in Yakutia were found to depend on the atmospheric blocking forming in Western Siberia. The correlation between total summer lightning stroke number in area of 1200 km radius around Yakutsk and frequency of atmospheric blocking in July at longitude of 70±5°E (Western Siberia) was -0.8. The total lightning number in Yakutia 1200-km radius area correlated with frequency of atmospheric blocking in July at longitude of 125±5°E (valley of Amur and Sungari Rivers) with coefficient of 0.56. The interannual variation of total lightning stroke number in Central Yakutia has been found to be linearly related to lightning activity in the eastern part of North Asia (valley of Amur and Sungari Rivers) of monsoon origin.
