Abstract

A positive correlation was found between annual variation of lightning activity and frequency of atmospheric blocking in July at longitude of around 70 ± 5 E (Western Siberia). There was also a negative correlation between frequency of atmospheric blocking in July in Western Siberia and lightning activity in the southeastern part at longitude of about 120- 130 E. It was confirmed by the spatial analysis of the blocking frequency and CAPE resulting positive correlation in the region of Western Siberia and negative correlation in eastern part of North Asia.
