The hose has been turned back on full-force over Northern California: A stream of moisture is flowing over the drought-riddled state and dropping copious amounts of rain just days after the close of one of the driest Januaries on record.

The influx of much-needed rain comes courtesy of a feature called an atmospheric river that is a key source of much of the state’s precipitation and water supply. A relatively recent meteorological discovery, these ribbons of water vapor in the sky are something scientists are trying to better understand. They are flying research planes into the heart of the current storm to study what fuels it, which could help improve forecasts of the events.
