A Relationship between Changes of Surface Air and Sea Floor Temperatures at the Arctic Shelf from the Coupled Models Intercomparison Project, Phase 6 Data
The sensitivity of seafloor temperature <semantics> T B </semantics> to the warming of surface air temperature <semantics> T a </semantics> is examined for 1850–2300, based on simulations with five models from the Coupled Models Intercomparison Project phase 6 ensemble and dr...
