This is sort of off topic, but I didn’t want to make a whole new thread about it.

‘Gravity waves’… that sounds interesting. I am assuming you are referring to those little radial pulses I keep seeing from the center (?). I just did a search but what I got was a bit over my head, and generally in context with mesoscale systems and the sort, not tropical cyclones. I seem to remember talking about them with Keith before, but I don’t think I understood them then either.

Could you explain their mechanics and function just briefly?

Thanks.
