Thunder

We had thunder this afternoon and a short but intense rain fell.

Thunder is an interesting weather phenomenon. I like the occasional thunder, as long as it does not disturb me when I sleep.

There are often a lot of echoes going around, when there is thunder. If I understand correctly, from reading on line, this is due to the vacuum and changes in air pressure by lightning, which causes the sound of thunder. It is fascinating. I wish I could understand it better.
