WICHITA FALLS, TX (TNN) - The Climate Prediction Center announced El Niño Weather Pattern last week.
An El Niño is simply warmer waters along the Pacific Equator; however, this change in the water temperature actually plays a big impact on the weather here in Texoma.
The sea surface temperature increases by approximately one degree for the first criteria.
The second criteria shows that temperature change must be present for a set amount of time. For El Niño, that period of time is five consecutive three month periods.
The El Niño pattern began in October 2018. The consecutive three-month periods are shown below with the sea surface temperature change.
The third criteria says we must have weaker trade winds, reduced cloudiness and rain fall, or an increase in pressure along the area near Indonesia.
How does that effect us? The El Niño shifts the subtropical jet right over us and brings moisture into our area, leading to an increase in precipitation and also brings cooler temperatures.
We can expect some cooler conditions, as well as maybe a little bit more precipitation.
