From Glossary of Meteorology
North Korea Cold Current
A southward flowing current along the northern Korean coast fed from the Liman Current.
At 37°–38°N it meets the East Korean Warm Current to establish the Arctic Polar Front of the Japan Sea. It is the source of the Mid-Japan Sea Cold Current, which withdraws water from it along its way to reinforce the polar front across the entire length of the Japan Sea.
