Weather: atmospheric rivers and the Pineapple Express

Self-tutoring about weather: the tutor mentions a couple of terms he’s managed to connect.

As I recall, here on Canada’s west coast, we used to hear about Pineapple Express weather systems back from 2000 to 2012 or so. As I understood, they brought tropical rain straight from Hawaii. I could believe that, too: I recall sometimes the weather might be drizzly and 5°C, but an hour later it was pouring rain and 11°C. I’d notice the temp increase indoors, and wonder what had happened. Stepping outdoors, under cover, felt almost like walking into a sauna. Such was the Pineapple Express at its finest.

To my knowledge, we didn’t call the Pineapple Express an atmospheric river back then, but that’s what it was. Apparently, an atmospheric river can produce a discharge comparable to that from the Mississippi River.
