Thunderstorm activity at high latitudes observed at manned WMO weather stations
Abstract Ongoing global warming particularly affects the coldest regions of our planet, where thunderstorm activity is considered to be the lowest. Scientific studies usually predict that lightning will become more frequent in polar areas in a warmer world. The aim of this study is to test this hypo...
