Back after 7 years, El Nino could bring extreme weather across globe
TORONTO (AA) – After seven years, surface waters in the mid-Pacific are warming leading to extreme weather conditions across the globe.
The changing weather patterns due to the El Nino effect are expected to cause droughts, floods and record-breaking rise in temperatures.
El Nino occurs when weak trade winds blowing west towards Asia fail to push warm surface waters in that direction.
It causes surface temperatures to rise by about 4-5 degree Celsius in the eastern tropical Pacific Ocean.
As it prevents cooler, deeper waters from rising to the surface, it causes changes in weather patterns in other parts of the globe.
The Pacific Ocean, Horn of Africa, Southeast Asia, and South America are among the regions that may be particularly impacted by the potentially extreme weather events.
Concerns are mounting around El Nino’s possible effects, with commodity markets expected to be impacted and food supply chains disrupted.
El Nino is part of a natural climate pattern called the El Nino/Southern Oscillation.
Seven years ago, a notably intense El Nino event developed in the Pacific, was responsible for changes in global weather patterns.
Indonesia experienced a severe drought that exacerbated devastating wildfires.
The Horn of Africa was inundated by heavy rainfall, flooding villages, and agricultural areas.
This event also contributed to 2016 being recognized as the hottest year on record.
With El Nino having made its return this year, experts are raising concerns of extreme weather in the coming months.
