A Survey on the Relationship between Ocean Subsurface Temperature and Tropical Cyclone over the Western North Pacific

Table 3

Mean TC lifespan during JASON season in the subsurface cold and warm years.

	TC lifespan (h)			C45 TC lifespan (h)
	Cold years	Warm years	Diff (cold-warm)	Cold years	Warm years	Diff (cold-warm)
JTWC	241.49	106.31	135.18	323.81	108.31	215.50
CMASTI	201.79	97.62	104.17	292.50	115.85	176.68

The difference is statistically significant at the 95% confidence level.
