The climatological mean TC genesis frequency distribution (count/10 years) from 1979 to 2010 in the (a) IBTrACS data, (b) HST run, (c) W2K run, and (d) W4K run. The number on the top right denotes the JASO-mean TC genesis number in the respective scenarios. The contrast of TC genesis density between (e) W2K and HST and (f) W4K and HST during JASO over the WNP based on the d4PDF ensemble for last 32 years. The cross-hatched region in (e, f) denotes that the difference in the TC genesis frequency is significant at the 95% confidence level.
