Odds are that La Niña will return this winter


From the Summit County Citizens Voice (Bob Berwyn):

While La Niña conditions (cooler-than-average sea surface temperatures in the eastern Pacific) often return for a repeat performance after a strong episode like last year’s, the second time around is often much less intense, with a less pronounced effect on Colorado’s winter weather…

In a La Niña watch issued Aug. 4, the CPC said readings from the central Pacific show a strengthening of the below-average temperature readings at depth, and some atmospheric circulation patterns are still echoing last winter’s La Niña, including enhanced convection over the eastern Pacific, around Indonesia and New Guinea, with suppressed convection over the central equatorial Pacific. About half the long-range models are now forecasting that La Niña will reform in the fall.
