Changing ocean circulation intensifies extreme events in the Indian Ocean

Previously, it was assumed that the tropical rain belt moves south globally when the oceanic circulation in the North Atlantic region weakens. Data and model simulations showed that during such phases, the Northern Hemisphere becomes drier and the Southern Hemisphere wetter.

The newly published study shows that this is also accompanied by a strengthening of the precipitation pattern in the Indian Ocean region. Here, East Indian Ocean and Indonesia become wetter, while the West Indian Ocean and East Africa become drier. Increased westerly winds in the tropical Indian Ocean, which transport heat and moisture from west to east, are responsible for this rainfall anomaly.

"We simulated different scenarios in the model, with varying changes in polar ice cover, solar radiation, and greenhouse gas concentrations to better understand the cause and effect of each parameter," said Dr. Mahyar Mohtadi, co-author of the study and head of the Low Latitude Climate Variability group at MARUM. As expected, the results showed a southward shift of the rain belt in the tropics and a weakening of the Hadley cell in the Southern Hemisphere.

"The models show that this weakening strengthens westerly winds in the equatorial Indian Ocean, which then provide higher precipitation and water temperatures and enhanced Walker circulation in the eastern Indian Ocean", Mohtadi said. This would lead to more and stronger flood events in the eastern part of the Indian Ocean and droughts and dry spells in the western part of the Indian Ocean.

In the future, the effects of global warming and weakened ocean circulation will compete with each other. "Instead, our study shows that this additional east-west component on a regional scale leads to a mutual amplification of these effects, which may make regions like Southeast Asia even wetter or East Africa even drier than expected," says Dr. Enno Schefuss, co-author of the study and head of the Molecular Paleoclimatology group at MARUM.

EU gives 'red card' to Cameroon over fishing
Brussels (AFP) Jan 5, 2023
The EU on Thursday gave a "red card" to Cameroon for failing to cooperate in the international fight against illegal fishing. The European Commission said in a statement it had identified Cameroon as a "non-cooperating country," earning the "red card" designation, and would ask EU member states to add the country to the bloc's blacklist. It said that was because Cameroon continues to register fishing vessels operating outside its waters without sufficiently monitoring their activities - includi ... read more
