I had never heard of these "atmospheric rivers" prior to this article and started doing a little reading. "Atmospheric rivers are typically several thousand kilometers long and only a few hundred kilometers wide, and a single one can carry a greater flux of water than the Earth's largest river, the Amazon River." [1] That's really impressive. I'm curious about their density and whether airplanes have to avoid them, or if they're able to fly through.
