arousal from
thunder and
lightning
This is one of many forms of arousal to be had with storms and inclement weather.
While tonitrophilia is the love of just thunder, karaunophilia includes thunder and lightning. Brontophilia is nearly similar, being the love of thunderstorms.
Also related are lilapsophilia, the love of tornadoes, and ombrophilia and pluviophilia, arousal from rain or being rained upon.
While I rather enjoy all of these but the tornadoes, my enjoyment does not reach the levels indicated by these conditions.
