Winter weather forecast: La Niña influences temperature and precipitation in the United States
16 october 2024 в 18:13
Winter is already on the horizon.
Despite predictions forecasting the return of La Niña by the end of summer, this natural climate pattern is now expected to develop later in the season, affecting temperatures, precipitation, and even snow across the United States.
Before the start of the 2024 hurricane seasons on June 1st, researchers widely anticipated a strong La Niña following a record multi-year period of warmer water in the eastern Pacific Ocean, known as El Niño. However, after a spike in tropical activity in September and early October, including two catastrophic hurricanes in Florida, the National Oceanic and Atmospheric Administration (NOAA) now predicts a weak La Niña event. The agency estimates a 60 percent chance of this pattern developing now and through November. Historically, only four such events have formed so late in the year since 1950.
It is expected that the entire northern belt of the US will be wetter than usual this winter, especially in the Pacific Northwest, Central West, and some parts of the interior Northeast. This wet weather will be critical in combating ongoing drought and dryness in the Central West.
This is completely opposite to last year’s winter pattern, which favored a wet south and dry north.
Meanwhile, the season is expected to be warmer than usual in much of the southern half of the US and a significant portion of the East. This may result in winter storms on the East Coast being more wet than snowy. However, with predicted drier and warmer conditions in the south, drought conditions may worsen throughout the season.
La Niña is expected to persist from January to March of next year.
El Niño and La Niña are two phases of the climate pattern known as the El Niño-Southern Oscillation (ENSO), and they significantly influence weather conditions worldwide.
El Niño Effects: During El Niño, conditions often lead to wetter and snowier weather in places like Amarillo. This can mean increased precipitation and cooler maximum temperatures in the winter months. For example, regions that typically experience dry winters may see a change, with more snow or rain, leading to improved soil moisture levels.
La Niña Effects: In contrast, La Niña usually brings drier and warmer temperatures. This phase can lead to prolonged periods of drought, making winter overall milder. However, it can also result in temporary extreme cold snaps that can catch people off guard. Think of it as a roller coaster: while the overall ride may be warmer, there can still be sudden drops into colder temperatures.
Frequency of Occurrence: These events typically occur every two to seven years, but El Niño occurs more frequently than La Niña
