Assessment of sea ice extent in CMIP6 with comparison to observations and CMIP5
Both the Arctic and Antarctic sea ice extents (SIE) from 44 coupled models in the Coupled Model Intercomparison Project Phase 6 (CMIP6) are evaluated by comparing them with observations and CMIP5 results. The CMIP6 multi‐model mean can adequately reproduce the seasonal cycles of both the Arctic and...

description |
Both the Arctic and Antarctic sea ice extents (SIE) from 44 coupled models in the Coupled Model Intercomparison Project Phase 6 (CMIP6) are evaluated by comparing them with observations and CMIP5 results. The CMIP6 multi‐model mean can adequately reproduce the seasonal cycles of both the Arctic and Antarctic SIE. The observed Arctic September SIE declining trend (−0.82±0.18 million km2/decade) between 1979 and 2014 is slightly underestimated in CMIP6 models (−0.70±0.06 million km2/decade). The observed weak but significant upward trend of the Antarctic SIE is not captured, which was an issue already in the CMIP5 phase. Compared with CMIP5 models, CMIP6 models have lower inter‐model spreads in SIE mean values and trends, although their SIE biases are relatively larger. The CMIP6 models did not reproduce the new summer tendencies after 2000, including the faster decline of Arctic SIE and the larger interannual variability in Antarctic SIE. |
