Since the climate response to the North Atlantic SST anomalies is primarily forced at the low latitudes and the AWP is in the path of or a birthplace for Atlantic tropical cyclones, the influence of the AMO on Atlantic tropical cyclone activity may operate through the mechanism of the AWP - induced atmospheric changes.

In fact, similar press conferences were held for two other papers (both also questioning the premise that climate change is likely to lead to an increase in tropical cyclone activity) by Wang and by Vecchi and Soden

A tropical cyclone is the generic term for a non-frontal synoptic scale low - pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).

While this study is undoubtedly an important contribution to the literature, introducing a potentially useful methodology for refining estimates of past tropical cyclone activity in all the major basins, it is hardly the last word (see e.g. the discussion thread in our previous article on the paper).

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.

The uncertainties in the historical tropical cyclone records, the incomplete understanding of the physical mechanisms linking tropical cyclone metrics to climate change, and the degree of tropical cyclone variability provide only low confidence for the attribution of any detectable changes in tropical cyclone activity to anthropogenic influences.

Such activity may extend to individual thunderstorms, but it is certainly expected also for tropical cyclones owing to their relationship with the ocean.

On the other hand, I don't know if there are correlation studies of the cyclone activity with the surface insolation trends in past decades and for each tropical bassin.

In looking at the accumulated cyclone energy index, COAPS at Florida State University noted that this was the lowest year for activity in the Northern Hemisphere since 1977, as the Atlantic, western Pacific and Eastern Pacific were all below normal in their activity.

There is observational evidence for an increase of intense tropical cyclone activity in the North Atlantic since about 1970, correlated with increases in tropical SSTs.

As the IPCC special report on extreme events put it «There is low confidence in any observed long - term (i.e., 40 years or more) increases in tropical cyclone activity (i.e., intensity, frequency, duration), after accounting for past changes in observing capabilities.»

Wang, X. L., V. R. Swail, and F. W. Zwiers, 2006: Climatology and changes of extratropical cyclone activity: Comparison of ERA - 40 with NCEP - NCAR reanalysis for 1958 - 2001.

The team then compared the oxygen isotope ratio for each year's wet season from 1990 to 2010 with a cyclone activity index of the average accumulated energy expended, based on factors such as number of cyclones, cyclone strength, size and time on storm track.

«Consequently, tropical cyclone activity across the western Caribbean may remain essentially stable over the current century, which has important implications for water availability in this region.

So, why do so many people believe that humans are causing an increase in cyclone activity, and that our fossil fuel usage is somehow to blame for these natural disasters?
