A study carried out by a team of scientists belonging to the University of Columbia, in the United States, revealed that there is an area of the Pacific Ocean known as the ” equatorial cold tongue, which does not heat up in a similar way as the rest of the waters in the world.
This region extends from Peru to the western Pacific, and has been kept cold because the winds known as “trade winds” are responsible for removing hot water on the surface of the place.
In an article published in the scientific journal Nature Climate Change, the scientists point out that this situation causes the colder waters coming from the depths of the sea to surface, causing the temperature in this place to be maintained and not suffer considerable increases.
Richard Seager, lead author of the study, revealed to Newsweek magazine that, due to Earth’s rotation, the winds drive the waters north and south of the equator.
According to Seager, the equatorial cold tongue is created “Because of the rotation of the Earth. the winds drives waters northward to the north of the Equator and southward to the south of the Equator. As the waters are driven away from the Equator water is pumped up from below and since the waters below the surface are cold this creates the equatorial Pacific cold tongue”.
This area has puzzled the scientific community for a long time, because advanced computer models on climate suggest that the waters of the cold equatorial language should have been heating up for decades at a faster pace than the rest of the Pacific.
However, experts estimate that this region tends to register a too high amount of humidity and wind speeds considered too low, causing the temperature of these areas in the sea to be sensitive to climate change, a situation that fortunately would not be happening as theoretically believed.
