Table 1 Correlation between typhoon intensification rate and various atmospheric and oceanic variables.

V|200−850, full shear; |Δu|200−850, shear of zonal wind; |Δv|200−850, shear of meridional wind; ζ850, 850-hPa vorticity; ω500, 500-hPa pressure velocity; SLP, sea-level pressure; PIinten, PI over the main intensification region; PIgenesis, PI over the main genesis region defined in ref. (21); RSST, SST over the typhoon intensification region relative to global tropical mean SST; T75m, ocean temperature at 75-m depth; rupper and rlower, the upper and lower bounds, respectively, for a 95% credible interval.
