Figure 2
From: Vertical Feedback Mechanism of Winter Arctic Amplification and Sea Ice Loss
Winter-averaged patterns of anomalous atmospheric condition: (a) 2 m air temperature (0.5 °C contour interval), (b) lower tropospheric (1000–900 hPa) geopotential height (red contour; 3 m contour interval) and wind (black contour), sea ice reduction (%, shading), (c) vertical cross section along 60 °E of lower tropospheric (1000–850 hPa) air temperature, geopotential height and wind, and (d) along 80 °N. Temperature is in shading (0.4 K contour interval), geopotential height is in black contours (3 m contour interval), and (c) zonal and (d) meridional winds are in blue contours (0.2 m s−1 contour interval). Figures were created with GrADS 2.1.0 (http://cola.gmu.edu/grads/).
