East indian winter jet

From Glossary of Meteorology

East Indian winter jet

A southward flowing powerful western boundary current that replaces the northward flowing East Indian Current along the east coast of southern India during October– December.

Its speed is consistently above 1 m s-1. It continues westward south of Sri Lanka, where it establishes a strong current shear but little water exchange with the eastward flowing Indian equatorial jet to the south. It feeds its water into the Arabian Sea.
