The EOF of rainfall after FFT high-pass filter (retain signal below 9 years): the first spatial mode (a) and corresponding temporal coefficient (c) and the second spatial mode (b) and corresponding temporal coefficient (d). (e, f) The correlation pattern between PC1, PC2, and autumn SST and 0.26, 0.31, and 0.4 denote critical values of significance t-test at 90%, 95%, and 99% confidence level, respectively.
