Polar vortex process: Our effort to gain control of Earth's weather begins by understanding how it works

摘要

IN automation and process control, the main rule is that one must understand a process before one can control it. My goal in this column is to describe the polar vortex process in terms of its formation, behavior and its response to warming. (I might add that the same could be done about flooding by just considering that the oceans were the warmest on record in 2018, that warm air holds more moisture, and that it returns by precipitation.)
