What is fairly hypocritical is to publicly claim that the data over the past few centuries is good enough to support this AMO explanation for hurricane activity, while at the same time claiming that the data is too poor to produce a statistically relevant trend over the past few decades.

But their findings, if potential intensity is a valid marker for hurricane activity is any measure, are quite clear: hurricane activity isnt going to change much even with 3C warming in the oceans.

According to the most recent evidence, there does not seem to be any sort of trend toward more hurricane activity and the signal for a possible increase in intensity is weak.

If one examines our model's control simulations for the 1982 - 2006 period, which show a trend towards increasing hurricane activity over this period, and correlates this activity with SST in the Main Development Region, and then tries to use this correlation to predict the 21st century behavior of the model, it clearly doesn't work.

Finally — it is not remotely necessary for a season to be as intense as 2005 in order for it to be very intense — after, all, 2004 (15 tropical storms, 9 hurricanes, 6 major hurricanes) had over 150 % of the activity of an average season, yet was much less active than 2005 (28 tropical and subtropical storms, 15 hurricanes and 7 major hurricanes.)

A recent paper by Vecchi and Soden (preprint) published in the journal Geophysical Research Letters has been widely touted in the news (and some egregiously bad editorials), and the blogosphere as suggesting that increased vertical wind shear associated with tropical circulation changes may offset any tendencies for increased hurricane activity in the tropical Atlantic due to warming oceans.

The shift in the PDO can have significant implications for global climate, affecting Pacific and Atlantic hurricane activity, droughts and flooding around the Pacific basin, the productivity of marine ecosystems, and global land temperature patterns.

«Research by NOAA scientists Gerry Bell and Muthuvel Chelliah, currently in press with the Journal of Climate, describes the tropical multi-decadal signal and shows that it accounts for the entire inter-related set of conditions that controls hurricane activity for decades at a time.

«The climate patterns responsible for the expected above - normal 2007 hurricane season continue to be the ongoing multi-decadal signal (the set of oceanic and atmospheric conditions that have spawned increased Atlantic hurricane activity since 1995), warmer - than - normal sea surface temperatures in key areas of the Atlantic Ocean and Caribbean Sea, and the El Nino / La Nina cycle»

The clear seasonality in TCs («hurricane season») with highest activities during the summer is one of the strongest pieces of empirical evidence that higher temperatures give more favourable conditions for tropical cyclones (After all, TCs only form in the warm tropics...).

NOAA also forecasts a high hurricane activity for the remainder of the season, and time will show if this season will match the 2004 in terms of number of tropical cyclones.

Because these changes exhibit a multi-decadel time scale, the present high level of hurricane activity is likely to persist for an additional 10 to 40 years.

For example, relatively few Atlantic hurricanes were observed in the 70s, 80s and early 90s, but there was considerable activity during the 40s, 50 and early 60s.

However, this increase is very likely a manifestation of a natural multi-decadal cycle of Atlantic hurricane activity that has been occurring for the last few hundred years.

Your statement here that «it is not possible for us to make any conclusions about effects of AGW on hurricane activity» is simply silly.

Considering that the mechanism of the «natural AMO» is so poorly understood, there's no justification for immediately blaming increases in hurricane activity on it while entirely ignoring global warming effects on sea surface temperatures (and atmospheric moisture), for which very clear mechanisms do exist.

«What's really important for Atlantic hurricane activity, what really gets things cranked up, is when the Atlantic warms relative to the rest of the tropics,» said Thomas Knutson, one of the paper's authors and a climate researcher at the Geophysical Fluid Dynamics Laboratory.

Hence it is not possible for us to make any conclusions about effects of AGW on hurricane activity.

Conversely, due to well - researched upper - atmospheric flow (e.g. vertical shear) configurations favorable to Atlantic hurricane development and intensification, La Nina falls tend to favor very active seasons in the Atlantic (El Nino years are the converse, with must less activity, as forecast by Gray and NOAA for 2009).
