Month-to-Month Variability of Autumn Sea Ice in the Barents and Kara Seas and Its Relationship to Winter Air Temperature in China

Figure 5

Composite differences for the (a) SLP (shaded and contour; unit: Pa), wind (vector; unit: m·s−1) at 850 hPa, and (b) surface air temperature (shaded and contour; unit: °C) between selected low OBKI years and high OBKI years in September. (c, d) The same as (a) and (b) but for the composite differences between the selected low DBKI years and high DBKI years in September. The shading denotes significance exceeding 0.1. The black vectors indicate winds with a northerly component over the area east of 100°E.
