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

Figure 3

Correlation coefficients between the BKI for September (a, d), October (b, e), and November (c, f) and the winter (DJF) temperature time series for 160 stations in China (shaded: significance and contour: correlation coefficient values) and the composite differences in the temperatures (dots; unit: °C) between selected low BKI years and high BKI years. The upper panels are for the OBKI, and the bottom panels are for the DBKI. Both the shaded areas and the dots indicate values that are statistically significant with significance exceeding 0.1 based on the results of t-tests. The values in the color bar represent the significance levels of the t-test.
