press release<\/p>\n

The importance of the Gulf Stream in contributing to Europe’s relatively mild climate is well known. Less known, however, is that the remote effects of the currents in the Indian Ocean also affect Europe.<\/p>\n

In an article recently published in the renowned journal “Nature”, an international team of scientists with the participation of the Leibniz Institute of Marine Sciences at the University of Kiel (IFM-GEOMAR) have revealed the Agulhas Current’s influence on Europe’s climate.<\/p>\n

Like the Gulf Stream, the Agulhas Current is one of the strongest currents in the world’s ocean, flowing into the Indian Ocean along the South African coast. The current makes an abrupt u-turn southwest of Cape Town back into the Indian Ocean.<\/p>\n

The Agulhas Current (red band) flow along the South African coast. The colors indicate the strength of the currents. Every three to four months, powerful vortices of more than 100 km in diameter, the Agulhas Rings, break off the main current. These rings bring warm saline water from the Indian Ocean into the Atlantic, thus serving a key role in the worldwide connected ocean currents. Some of the water from the Indian Ocean lands in the North Atlantic, and through the Gulf Stream also affects Europe’s climate.<\/p>\n

“It sounds a little bizarre that currents from South Africa have an influence on our region,” says the co-author of the study Arne Biastoch, a professor at the IFM-GEOMAR. Nonetheless it has long been known that the Agulhas Current plays an important role in the supple of salty water into the Atlantic. Biastoch has already published several key papers on the subject, although in this recently published international study, the existing knowledge of different research groups was compiled.<\/p>\n

In addition to describing simulations with ocean models, the researchers used measurement data to describe the phenomenon and its influence on the Atlantic.<\/p>\n

Above all, the focus was on the changes caused by global warming which could lead to an increased influx of water from the Agulhas Current into the Atlantic. Usually, western winds in the Southern Ocean limit the water exchange between the Indian Ocean and the Atlantic. Rising temperatures lead to a shift of the westerly wind belt south, however, widening the range for the inflow of water south of Africa. Model simulations indicate that this trend will only increase.<\/p>\n

The water introduced into the Atlantic Ocean is transported north along the Brazilian coast, until it finally finds its way into the Gulf Stream in the Caribbean. The warm and salt-rich water from the Indian Ocean finds its way into the North Atlantic through increased precipitation and melting ice. This is associated with a weakening in connection with the Gulf Stream.<\/p>\n

“We suspect that the supply from the South has played a crucial role in the transitions between glacial and interglacial periods,” explains Biastoch. “The long-range effect of the Agulhas Currents very clearly shows the complexity of the interactions in our climate system and global connections of ocean currents.”<\/p>\n
