Sometimes it is useful to know where there are lightning strikes taking place across Europe: for example, there are some theories linking sporadic-E propagation to a secondary effect of lightning, although I forgot where I read this. Also, it is useful to know how noisy the VLF and LF bands are likely to be as a result of sferics from such strikes.

Lightnings have many effects on radio propagation, not only on Es. Well, about Es its a supposition. It's not confirmed.
