Route 10 · Event cards

Every event since 1940, and the winter it brought.

Forty-odd El Niños and La Niñas in eighty-six years. Each card shows the event's path on MEI-ERA5, how high it peaked, how long it lasted, and its integrated intensity, the index summed over the whole episode, so a long moderate event can outrank a short spike. Beneath each are the U.S. temperature and precipitation of its winter, division by division.
