Because warmer air can hold more moisture, atmospheric rivers can carry bigger cargoes of precipitation. Specifically, the lingering water vapor from the January eruption could indirectly help to fortify the polar vortex over the North Pole, preventing it from dipping down across North America. This year is already wetter than last years 2021 total, and is as wet as the total precipitation for 2020, the first year of this drought.
