See how this natural phenomenon in the Equatorial Pacific could influence weather to come
A La Nina climate pattern has developed and is likely to persist through the winter, according to an advisory issued today by NOAA’s Climate Prediction Center.
La Nina — translated from Spanish as “little girl”— is a natural ocean-atmospheric phenomenon marked by cooler-than-average sea surface temperatures across the central and eastern Pacific Ocean near the equator, the opposite of El Nino (“little boy”) which features warmer-than-average sea surface temperatures in that region.
“La Nina can contribute to an increase in Atlantic hurricane activity by weakening the wind shear over the Caribbean Sea and tropical Atlantic Basin, which enables storms to develop and intensify,” said Mike Halpert, deputy director of NOAA’s Climate Prediction Center. “The potential for La Nina development was factored into our updated Atlantic hurricane season outlook issued in August.”
