La Nina done, U.S. CPC says

Neutral weather likely through summer

Reading Time: < 1 minute Reuters — A U.S. government weather forecaster said on Thursday La Nina has ended and El Nino-Southern Oscillation (ENSO) neutral conditions are likely to continue through the Northern Hemisphere summer. “ENSO neutral” refers to periods in which neither El Nino nor La Nina is present, often coinciding with the transition between the two weather patterns, […] Read more

La Nina to bring colder, drier winter

Reading Time: 2 minutes MarketsFarm — There’s a La Nina poised to exert influence on the coming North American winter, according to Drew Lerner, senior agricultural meteorologist for World Weather Inc. in Kansas. A La Nina generates colder-than-normal temperatures, as opposed to the warm temperatures garnered from an El Nino. Both weather phenomenon can be found over the Pacific […] Read more

La Nina present, 75 per cent chance seen through 2020 winter

Reading Time: < 1 minute Reuters — La Nina conditions were present in August, and have a 75 per cent chance of continuing through the Northern Hemisphere winter of 2020-21, a U.S. government weather forecaster said on Thursday. The La Nina pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean. A borderline moderate La Nina event is […] Read more

El Nino, La Nina patterns not seen prevailing during summer

Reading Time: < 1 minute London | Reuters — Sea surface temperatures in the tropical Pacific remain neutral, meaning that neither El Niño nor La Niña weather patterns are prevailing, the U.N. World Meteorological Organisation said on Thursday. The El Niño pattern brings a warming of ocean surface temperatures in the eastern and central Pacific every few years, and is […] Read more

El Nino likely not responsible for warm, dry conditions

Reading Time: 2 minutes CNS Canada — The above-normal temperatures Western Canada has generally experienced since the fall weren’t necessarily caused by an El Nino. Rather, to Agriculture and Agri-Food Canada, the phenomenon that’s likely affected the weather was a ‘blob’ that formed off of the coast of British Columbia. “It’s a big warm pocket of ocean water and […] Read more

U.S. forecaster sees 90 per cent chance of El Nino in winter

Reading Time: < 1 minute Reuters — There is a 90 per cent chance of the El Nino weather pattern emerging during the Northern Hemisphere winter of 2018-19, a U.S. government weather forecaster said on Thursday. “The official forecast favours the formation of a weak El Nino,” the National Weather Service’s Climate Prediction Center (CPC) said in a monthly forecast.

La Nina seen likely to fade by spring

Reading Time: < 1 minute Reuters — The current La Nina weather cycle is likely to transition into more neutral conditions by spring, a U.S. government weather forecaster said Thursday. La Nina is characterized by unusually cold ocean temperatures in the equatorial Pacific Ocean and is linked with floods and droughts. It is the opposite phase of what is known […] Read more
