Atmospheric Rivers and Lakes
Atmospheric lakes and rivers are a relatively recent discovery and are exactly what they sound like. Aerial rivers are very amazing, and the idea of them is a little older than lakes. An atmospheric river is a stream of water vapor in the atmosphere that can spread out over 400 miles and reach lengths of 1000 miles. When they come down, they can dump a ton of water. up to 25 Mississippi rivers' worth of water. There's also the more recently found atmospheric lake if that's a little too intense for you.
An atmosphere lake is a large body of water vapor in the clouds, similar to an atmospheric river but not moving as quickly. In essence, it resembles a lake in the sky. The atmospheric lake discovered over the Indian Ocean was thought to contain enough water to form a puddle 620 miles wide but just a few inches deep, in contrast to the river, which sounds quite intense. They originate in tropical locations close to coastal areas and migrate in places with absolutely no wind at all. They can also continue for almost a week since they move slowly, providing rain to frequently extremely dry and desert areas.
