Relationship between the Barents Sea ice retreat and atmospheric response
Abnormal winter sea-ice retreat over the Barents Sea has been considered as a leading clue to the recent mid-latitude severe winters. Barents Sea is considered as a hot spot for the rapid Arctic climate change due to the intense air-sea interaction induced by the sea-ice decrease; however, the under...
