Rossby Waves
We call it "weather whiplash." This is not just meteorologists being funny. It is a phenomenon that perhaps has always been with us to some degree, but that has recently become much more common, apparently. If you were under the impression that there is a lot of strange weather going on out there, you may be right, and weather whiplash may be the phenomenon you've noticed. Importantly, there is good reason to believe that weather whiplash is the result of anthropogenic global warming. In other words, it's your fault, so please do pay attention.
