Short summary

The NW Indian Ocean is the siege of two very intense anticyclonic eddies, the Great Whirl and the Southern Gyre, the rapid development of which makes their observation difficult. Model simulations propose an interaction scenario between the two eddies not described in observations up to now. When the summer monsoon intensifies, the Southern Gyre moves northward, collides with the Great Whirl and takes it place. The Great Whirl is pushed to the east of Socotra Island and forms the Socotra Eddy.
