U.N. Weather Agency Says No El Nino Or La Nina This Year

UNITED NATIONS (UPI) — The Pacific Ocean will probably not have an El Nino effect or its La Nina opposite number through the end of the year, the U.N.’s weather agency said Wednesday.

The World Meteorological Organization said forecasts predicted climate patterns in the Pacific are likely to remain neutral, a United Nations release reported.

Temperatures, sea level pressure, cloudiness and trade winds have generally been at neutral levels, the WMO said, indicating that neither warming El Nino nor cooling La Nina conditions have been present.

El Nino conditions occur every two to seven years, causing a significant shift in rainfall patterns, often causing floods in usually arid countries in western South America and drought in the western Pacific.

El Nino events are often followed by La Nina conditions, a swing to unusually cool ocean surface temperatures in the central and eastern tropical Pacific.

The far eastern tropical Pacific Ocean temperatures cooled to well below average during May and early June, approaching “a borderline La Nina level,” the WMO said, but “the ocean-atmosphere system as a whole did not remain in a La Nina state for long enough to be considered a weak La Nina event.”
