Climate phenomena could have a stronger impact
They have now published their results in the journal Science Advances. They establish a connection between the different layers of water in the Indo-Pacific Warm Pool, which push the circulation system through their different temperatures. The Indo-Pacific Warm Pool, located in the equatorial East Indies and in the equatorial West Pacific, has a great influence on the climate worldwide and is considered – due to high temperatures – as the engine of the global atmospheric circulation.
The authors conclude that until 4,000 years ago, higher water temperatures in the Indo-Pacific Warm Pool have attenuated climate phenomena such as El Niño. However, this mechanism has reversed and could now lead to a stronger effect of these climate phenomena in the future.
