(a) Sea-ice extent area on March 13, 2026.
The sea-ice edge (15% sea-ice concentration) is located between the white and blue areas. Brown lines show the 2010s mean sea-ice edge for the same date.

(b) Air temperature anomalies (°C) at the 925 hPa relative to the 2010s mean for (left) January and (right) February 2026 based on atmospheric reanalysis data (NCEP-NCAR Reanalysis 1,note 5).
Black lines indicate air temperature (°C) on the same year and month. Yellow-to-red and light blue-to-dark blue shading indicate warmer and colder than the 2010s mean, respectively.
