The La Nina weather pattern typically spells below-normal temperatures in the northern hemisphere and has prompted regional weather agencies to issue warnings about a frigid winter. La Niña delivers drier warmer and sunnier weather along the southern tier of the United States from California to Florida. El Niño and La Niña have the strongest influence on year-to-year climate variability for most of the country.

Our second-year La Niña has materialized as indicated by the ocean and atmosphere in the tropical Pacific. La Niñas natural cooling of parts of the Pacific is the flip side of a warmer El Niño pattern and sets in motion changes to the worlds weather for months and sometimes years. Average sea surface temperatures in the Niño-34 region of the equatorial Pacific Ocean were at least 05C 09F warmer than average 5N-5S 120W-170W in the preceding month and the anomaly has persisted or is expected to persist for 5 consecutive overlapping 3-month periods eg DJF JFM FMA etc and the atmosphere over the tropical Pacific exhibits.

This means that places like Indonesia and Australia can get much more rain than usual. The ENSO cycle loosely operates over timescales from one to. And around the world.

And places like the southwestern United States can be very dry. They are part of a natural cycle known as the El Niño-Southern Oscillation ENSO. Episodes of El Niño and La Niña typically last nine to 12 months but.

NOAA announced that La Niña was officially underway back in August and issued a La Niña advisory as it will continue to influence the weather pattern in the coming months. Since these have a weaker influence on the atmosphere it is difficult to find local trends with past weak La Ninas. La Niña is one phase of a weather pattern known to climatologists as El Niño Southern Oscillation ENSO which affects the whole Pacific basin and beyond and is the major climate pattern after the seasonal cycle.

Weather Patterns Prevailing Across Colorado During Weak La Niñas. The La Niña climate pattern a natural cycle marked by cooler-than-average ocean water in the central Pacific Ocean is one of the main drivers of weather in the US.

Spanish for little girl La Niña is the less famous counterpart of El Niño a temporary warming patternTogether they form one of the worlds most important weather-making phenomena. The oceans play an important role in Earths weather.

La Niña weather patterns can cause drier than average years in some. El Niño and La Niña are two opposing climate patterns that break these normal conditions. This winter likely will be colder.
