Could climate change alter El Nino pattern?
Could climate change alter El Nino pattern? "Earth is reflecting less light as its climate continues to change, new research suggests.
A beautiful phenomenon connects climate and brightness: clouds. Clouds are a notoriously complicated piece of the climate puzzle — scientists struggle to model how clouds will respond to climate change and how those responses in turn will shape the future climate. But the scientists behind the new study think that the reflectivity finding hinges on the dynamics of clouds over the Pacific Ocean.
In particular, the CERES data noted a loss of bright low-altitude clouds over the eastern Pacific Ocean, off the west coast of the Americas, where scientists are also registering stark temperature increases at the ocean surface."

"Although the exact initiating causes of an ENSO warm or cool event are not fully understood, the two components of ENSO – sea surface temperature and atmospheric pressure are strongly related. During an El Nio event, the easterly trade winds converging across the equatorial Pacific weaken. This in turn slows the ocean current that draws surface water away from the western coast of South America and reduces the upwelling of cold, nutrient–rich water from the deeper ocean, flattening out the thermocline and allowing warm surface water to build in the eastern part of the basin."
