Attached are analyses of Willis’s landfalling hurricane data in post # 35. Interesting facts:
1. 1974-2005 trend is "n.s." (Note 95% confidence intervals now present.)
2. PACs for lag 10 and 20 are marginally significant. (Recall that for total # hurricanes lag 5 and 10 were sig. It is as though NAO affecting sea storms is operating on a 5y time-scale and continental high (blocking effect from decadal/bidecadal solar cycle?) is operating on a 10/20y cycle. Not sure if this has been noticed in the literature because I don’t read that literature. But I know that continental drought in the US is weakly forced by the 11/22y solar cycle, so why not the process of hurricane landfall? (i.e. You take your pick: hurricanes in 2005 are the ultimate solution for droughts in 2001-2003!) Note how this fits nicely with your "persistence" theory!
