图3. 标准化后白令海最大海冰面积的时间序列(黑实线)(a)及其经验模态分解后前3项序列IMF1(b)、IMF2(c)和IMF3(d):(a)中也包括标准化的冷池面积指数(红线)、白令海东部陆架区春季表层水平均温度(蓝虚线)和底层水平均温度(灰虚线)

Fig. 3. The standardization time series of the maximum sea ice area (a) in the Bering Sea and its first three Intrinsic Mode Function (IMF1~IMF3), (b), (c), (d) acquired by the Empirical Mode Decomposition approach. Panel (a) includes the standardized cold pool area index (red line), the spring average sea surface temperature (blue dotted line) and the bottom sea temperature (gray dotted line) of the eastern shelf area of the Bering Sea as well
