La Nina “Favored To Emerge In September-November” & “Persist Through January-March 2025”<\/span><\/p>\n

\n

The National Weather Service’s Climate Prediction Center wrote on X this past week that the\u00a0probability of a La Nina weather pattern now stands at 71% and “is expected to persist through January-March 2025,” adding, a “La Nina watch remains in effect.”\u00a0<\/p>\n

La Nina odds are currently higher, yet CPC expects the weather phenomenon to be “weak.”\u00a0<\/p>\n

“A weaker La Ni\u00f1a implies that it would be less likely to result in conventional winter impacts, though predictable signals could still influence the forecast guidance,” the weather agency wrote in an update.\u00a0<\/p>\n

La Nina patterns occur when sea-surface temperatures along the equator in the Pacific Ocean cool. The cooler waters push the jet stream northward, allowing more precipitation across the western US. Due to the movement of the jet stream, areas of the southern US record less precipitation than normal during La Nina patterns.<\/p>\n

Ben Noll, a meteorologist with New Zealand’s National Institute of Water & Atmospheric Research, provided more color about the La Nina weather pattern on X:\u00a0<\/p>\n

The ocean has taken some significant strides toward La Ni\u00f1a thresholds in recent weeks.\u00a0<\/em><\/p>\n

Trade winds have been much stronger than normal, causing upwelling of cooler, sub-surface waters. <\/em><\/p>\n

This year, the sub-surface is quite a reservoir of cooler than average water, primed to be moved toward the surface as wind stresses come and go.<\/em><\/p>\n

Traditional indices suggest this year’s La Ni\u00f1a will be of a weak to moderate variety. <\/em><\/p>\n

However, alternative approaches like the Relative Oceanic Ni\u00f1o Index (RONI) offer a different view. This index, which compares the sea surface temperature anomaly in the central equatorial Pacific with the rest of the global tropics, is a better indicator of the ENSO-related change of rainfall and thunderstorms patterns, particularly in a warming world. <\/em><\/p>\n

RONI suggests that a moderate to borderline strong La Ni\u00f1a is possible. In fact, recent values of RONI have dipped to -0.75\u02daC, in La Ni\u00f1a territory!<\/em><\/p>\n

On the balance of recent trends and guidance, and considering the increasing frequency of La Ni\u00f1a in recent decades, I continue to think that La Ni\u00f1a 2024-25 has room to develop into a formidable event…<\/em><\/p>\n
