I just sent him an email an hour ago asking if this was going to be made available. It is nice to see his results are quite close to what I found when I looked at this question back in February. http://iconicmidwest.blogspot.com/2007/02/what-have-i-been-doing.html Landsea states: Assuming that a similar long-term average of about 59% of tropical cyclones actually struck land during 1900–1965, this increases the record by 2.2 additional tropical cyclones per year for this earlier era. I found for the years 1907-1966: If we look at the minimum (14.44%) and maximum (24.53%) values as defining a range for the pre-satellite number (which today sits at 40 Mid-Atlantic storms out of 495 total storms, or 8.08%,) we are left with a range of an additional 1.28 to 2.46 storms per year. That would mean a difference for the sixty year period of plus 77 to 148 storms. Sounds good to me. :-) However, Landsea's graphs are prettier than mine. I should have checked here first.

cyclones per year for this earlier era.
