Emanuel 2005 stated: The accumulated annual duration of storms in the North Atlantic and western North Pacific has indeed increased by roughly 60% since 1949, though this may partially reflect changes in reporting practices, as discussed in Methods. Speaking of “rudimentary statistics”, this seems like a rudimentary statistical statement. But there are wheels within wheels.
A couple of days ago, I posted up my attempt to replicate Emanuel 2005 Figure 1 (Atlantic PDI) and today post up a similar exercise on W Pacific PDI. While most hurricane discussion is focussed on the Atlantic, the PDI in the W Pacific is about 5 times larger. Emanuel said: I maintain that current […]
Willis writes: I wanted to see if there was acceleration in the TOPEX sea level record. I have looked all over the web to find either the data used to create the following image of the sea level rise as measured by the TOPEX satellite, available here, or some estimate of any acceleration that might […]
Hot off the press this week is a study on foraminera over the last millennium in the Indo-Pacific Warm Pool – something that you’d think would be relevant to Hansen’s attempts to splice modern instrumental records to core tops ending in the Holocene Optimum. Newton et al 2006 have the following abstract:
Interesting presentation by Bill Gray posted up here . I’ve just scanned through it but I’m sure that it will cause much controversy. Please also consider the critique of Bill Gray at realclimate here . The only areas that I have personally examined data and methods are for proxy data, where obviously I feel that […]
I’m in the process of trying to replicate some of the hurricane papers. Obviously this is new territory for me – so forgive me if I’m going over old ground. Emanuel Figure 1 states in its caption that "total Atlantic hurricane power dissipation has more than doubled in the past 30 yr" and David Stockwell’s […]
I’ve collated some hurricane track data in flat text files so that they are more usable (at least for me) and have posted up the working files since there seems to be interest in this data. I’m also posting up some notes on fiddly format issues while they are fresh in mind.
Earth to climate scientists: no one uses Fortran punchcards anymore. When you put data onto the web, it doesn’t have to fit onto 80 columns as though it were a punchcard. Also when home computers have 100 GB of memory, you don’t have to squish multiple records onto one line. Hurricane track data as archived […]
Willis writes: Well, looking at these studies is giving me a headache. My latest one is High frequency variability in hurricane power dissipation and its relationship to global temperature, James B. Elsner et al.
Here are Judith Curry’s Comments on the Wegman Report. I appreciate these sorts of contributions and am obviously relying on such contributions (Willis, bender, etc.) more and more.
