There are many mysteries about the world’s oceans, from unexplored trenches to the Bermuda Triangle, but one of the strangest phenomena is that a large part of the Atlantic suddenly dropped in temperature..
Until March, the mid-Atlantic had the warmest weather since 1982, with temperatures reaching 30 degrees Celsius, however, significant temperature fluctuations followed, with surface water temperatures falling below 25 degrees Celsius..
Currently, scientists are monitoring the strip of water that stretches a few degrees on either side of the equator between Brazil and the East African coast.
They explained that the matter is related not only to the decrease in temperature of this region, known as the central tropical Atlantic Ocean, but also to the speed of change, and the central tropical Atlantic Ocean goes through its own temperature cycle every year, at find his. highest points in March and April before cooling during the summer..
Beginning in June, however, surface water temperatures began to drop at an unprecedented rate, and by mid-June, temperatures in that region were 0.5-1.0°C cooler than average for that time of year. ..
Now, water temperatures are starting to rise back towards normal levels Generally, the cooler summer waters in the Atlantic are associated with stronger trade winds blowing over the equator, causing warm surface waters to be swept into the waters deeper cooler, rising to the surface in the air. a process known as tropical upwelling, but the winds in the region which is experiencing a rapid cooling were weaker than usual this year.
Michael McFadden, of the National Oceanic and Atmospheric Administration, said (NOAA)Although climate change cannot be ruled out as a cause, it is unlikely to be responsible.
The scientists pointed out that the event could be linked to the arrival of the “Atlantic La Niña” phenomenon. Like El Niño and La Niña in the Pacific, the Atlantic El Niño/La Niña represents extreme peaks and troughs of ocean warming and cooling cycles..
If water temperatures remain below average for 3 months, that is enough to classify the condition as Atlantic La Niña, which has not happened since 2013. nearby weather systems..
