La Niña Forecast Update: Delayed Onset Expected
The United Nations has revised its forecast, indicating that the La Niña phenomenon, typically associated with lower temperatures, may be delayed and not reach its expected peak by the end of this year.
The World Meteorological Organization (WMO) now estimates a 55% probability of neutral conditions giving way to a La Niña episode between September and November 2024.
This revised forecast is a decrease from the WMO’s previous estimate in June, which predicted a 60% chance of La Niña in July-September and 70% in August-November.
Understanding La Niña
La Niña is characterized by the cooling of ocean surface temperatures in the central and eastern equatorial Pacific. This phenomenon is linked to changes in tropical atmospheric circulation, including winds and precipitation patterns.
The effects of La Niña vary depending on its intensity, duration, and timing, as well as its interaction with other climate phenomena.
According to the WMO, La Niña and its counterpart, El Niño, are natural phenomena that now occur in the context of human-induced climate change, which contributes to rising temperatures and extreme weather events.
