Halmahera eddy

From Glossary of Meteorology

Halmahera Eddy

A recirculation system between the South Equatorial Current and the North Equatorial Countercurrent in the extreme west of the Pacific Ocean, east of Halmahera.

The circulation, about 1000 km in diameter, is clockwise from April–November but reverses during December–March when the Philippines experience monsoon winds blowing from the northeast in the Northern Hemisphere and from the northwest south of the equator.
