Mediterranean deep water

From Glossary of Meteorology



Mediterranean Deep Water

(Also called Western Mediterranean Deep Water.) A water mass that occupies the Eurafrican Mediterranean Sea below a depth of 500 m.

It is formed in winter by convection in the Ligurian Sea and the Balearic Basin when very cold Siberian air is channeled through Alpine valleys and descends in a burst known as mistral to cool the sea surface.
See deep water.
