UN weather agency: Strong El Nino to develop quickly in the coming months

On 'Friday, the United Nations weather agency raised its forecast of the rapid emergence in the coming months of a strong El Nino. It warned that this 'phenomenon will likely drive global temperatures up.

El Nino, a periodic heating of the sea surface temperature in the eastern and central Pacific Ocean that lasts typically between nine and twelve months, can increase global temperatures, and increase the risk for extreme weather.

Alvaro Silva is a WMO scientist. He said, "El Nino has emerged in the Equatorial Pacific. There is remarkable agreement between forecast models on the strength of this El Nino."

Silva stated that the intensity of El Nino was important as it increased the probability of extreme weather events and climate changes in different parts of the globe.

Early June, the WMO?had predicted a moderate El Nino or a?possibly strong El Nino. However, recent forecasts have given the WMO more confidence that conditions for a strong El Nino are developing in equatorial waters of the Pacific. WMO could revise its forecast further if later information indicates a very powerful El Nino.

WMO seasonal forecasts show a "strong and robust" pattern of El Nino. This includes drier conditions than normal in many parts of the world including Central America, Caribbean and North and South America. In South Asia, during the monsoon, drier patterns are predicted in Indonesia and South East Asia.

El Nino will also boost global temperatures. Silva stated that we 'know' that global temperatures usually reach a?record level during El Nino.

Experts said that Europe experienced the worst heatwave ever recorded between June 20 and 28. This caused disruptions to electricity generation, infrastructure damage, and overwhelmed healthcare systems. Scientists said that climate change was most likely to blame for the 'extreme heat'.

Silva said that El Nino's effects will be felt across the globe until 2027. (Reporting and Editing by Linda Pasquini and William Maclean, with Olivia Le Poidevin)
