1.Reduction in ocean heat transport at 26°N since 2008 cools the eastern subpolar gyre of the North Atlantic Ocean
- cause: the slowing AMOC(Atlantic Meridional Overturning Circulation) ? the reduced ocean heat transport at 26°N
- location: south of Greenland-Iceland
- characteristic: ＞2℃ colder in 2016
- uplift of the thermocline
- the reduced northward temperature and salinity
- dramatic wintertime mixing
- effect: connected with Pacific decadal variability
- associated with a high pressure region that led the record warm, dry summer in 2008 in UK
2.Multiple drivers of the North Atlantic warming hole
- Increased ocean heat transport out of low-latitude region into higher latitudes and a shortwave cloud feedback dominate the formation and temporal evolution of the warming hole under green house gas forcing.
- Anthropogenic forcing caused accelerating ocean heat transport
