Strength of the lightning activity in the territory of Azerbaijan Republic

In this paper, sufficient statistic data (for a period of over 40 years) on thundery days and thundery hours are presented for the whole territory of the Azerbaijan Republic. Based on these materials, new maps on mentioned characteristics of the strength of thunderstorm activity have been drawn and a diagram giving duration of thunderstorm as a function of the number of thundery days has been plotted. It is presented both in power and exponential dependence. These maps will make it possible, when designing the lightning protection of various objects, to more accurately choose required characteristics of their protection from LS.
