Effects of long-term La Niña-like warming in the tropical Pacific on synoptic-scale wave activity (shading) and TC track density (contour) in the MRI-AGCM3-2-H experiments in the WNP ((−1.5, −0.5) blue contours). As the SST trend in the experiments between the periods 1981–2010 and 2020–2049 shows a cooling in the tropical Pacific (Extended Data Fig. 7 ), the differences in synoptic-scale wave intensity and TC track density are considered to be forced by La Niña-like global warming pattern. The averages of changes are shown for TC peak seasons in each basin (that is, JASO for the WNP).
