Extended Data Fig. 2: Statistical significance testing of grid point air-sea correlations.
From: Signature of the western boundary currents in local climate variability
Grid point correlation coefficients of (a, c, e, g) vertical motion anomalies at 850 hPa correlated with SST anomalies and (b, d, f, h) high-pass spatially filtered precipitation anomalies correlated with SST anomalies. Hatching indicates statistically significant values using a two-tail Student’s t-test at 99% confidence with 96 degrees of freedom. See Methods for more details. The rows correspond to the four western boundary currents of interest. Results are based on monthly mean ERA5.
