Figure 6
Vertical-meridional section showing longitudinally averaged atmospheric and oceanic fields covering Bering-Chukchi region in winter 2017–18. (a) Three-month mean atmospheric fields averaged from 160°E to 210°E in winter 2017–18. Color: warm air temperature anomaly; Arrow: northward and upward wind anomaly; Contour: positive specific humidity anomaly. Contours of positive specific humidity anomaly are shown at an interval of 0.1 g kg−1. Hatching areas show that the temperature anomaly exceeded two times as large as one standard deviation. (b) The sum of latent and sensible heat flux anomaly, upward direction defines positive (red), and downward is negative (blue). The width of one standard deviation was drawn by broken lines. (c) Three-month mean oceanic fields along 191°E in winter 2017–18. Black-boxed area corresponds to the region of the Bering Strait. Shade: ocean temperature anomaly. Arrow: time change of northward ocean current from 12 November to 15 February in 2017–18 winter, minus climatological time change. Contour: time change of temperature from 12 November to 15 February in winter 2017–18, minus climatological time change. Solid line indicates time change of ocean temperature is positive—i.e., warming; whereas broken line is negative—i.e., cooling. Contour interval is 0.01 °C day−1.
