Left (right) panels show the monthly composite maps of positive (negative) W4 years from October (− 1) to May (0) in SST anomaly (in °C). (− 1) suggests the preceding year of the event year (0). Hatched areas represent the values satisfying 95% confidence with a two-tailed t-test. In this analysis HadISST data are used.
