An invisible, unpredictable atmospheric force is wreaking havoc across the globe, sinking superyachts and bringing down planes. Follow scientists as they race to understand these catastrophic weather events, exploring how they form, what causes their devastating impacts, and how we might someday learn to predict them. From high-tech simulations and drone expeditions into thunderclouds to possible links with climate change, join investigators on the cutting edge of research to discover what's truly behind these terrifying "rain bombs" and how we can protect ourselves from their growing power.

(3,801 posts)like they're some new weather phenomena. I don't think that's a good thing. Are we going to start calling thunderstorms Lightning Bombs next? Plus these are very hard to forecast precisely. Any thunderstorm can collapse without a "cold pool" and cause a sudden downburst/microburst. Simple rain can mix down 50+ mph winds from 10k feet in the right conditions. Calling them Rain Bombs is just going to give people with there faces stuck to their phones something else to complain about. "OMG, we got hit by a Rain Bomb and there was no warning!! Eeeek!" lol. Good Doc for awareness but call it what it is. (And trust me, unless you live in the desert you aren't likely to see one coming)

I know that these presentations can seem a little over dramatic, but humans tend to minimize the dangers and risks of severe weather and climate change. Maybe documentaries like this will bring more attention to the topic.
I looked up Ted Fujita, the originator of the F-scale classification of the severity of tornadoes. I knew that he began with studying microburst/downbursts, but I didn't realize that it was as late as 1975. For some reason, I thought his studies of this subject began earlier. I know he first began studying the ground patterns left by destructive winds after the dropping of the atomic bombs on Japan during World War 2, but I hadn't remembered that his studies of downbursts came much later.
Thanks again for sharing and giving my curiosity a nudge.
