AMERICANALMANAC (Sadie Smith) - A potentially historic El Niño could collide with the polar vortex this winter — and scientists admit they don't fully understand what happens next
NOAA forecasts a "very strong" El Niño developing in the equatorial Pacific, possibly among the strongest in the modern record, yet the scientists tracking it concede the climate pattern's interaction with the polar vortex remains an open question with no reliable answer.

NOAA forecasts a "very strong" El Niño developing in the equatorial Pacific, possibly among the strongest in the modern record, yet the scientists tracking it concede the climate pattern's interaction with the polar vortex remains an open question with no reliable answer. The federal agency's characterization lands at a moment when Americans from the mid-Atlantic to the Pacific Northwest are trying to plan for a winter season that could swing between unusual mildness and punishing cold, depending on atmospheric forces that even top researchers describe in terms of probability, not certainty. Four scientists from NOAA, MIT, Johns Hopkins, and the University of Miami each offered USA TODAY variations on the same theme: we know a strong El…Open
