Not exact matches

Several recent studies such as Emanuel (2005 — previously discussed here) and Hoyos et al (2006 — previously discussed here) have emphasized the role of increasing tropical sea surface temperatures (SSTs) on recent increases in hurricane intensities, both globally and for the Atlantic.
With regard to Williams answer to Terry (# 34), I believe that Terry is correct that it is temperature differences that are fundamental, and not, for the most part, the temperature itself, as Emanuel has discussed in a series of important papers on the maximum intensity that hurricanes can attain.
The current Landsea / Trenberth / Emanuel discussion has been parsed by many to mean that Landsea claims that the number of hurricanes is constant, and Trenberth is claiming that their intensity should increase as global warming heats the ocean surface.
So the policy idea is to greatly reduce GHGs so as to reduce future hurricane intensity (& use savings from those reductions to storm - proof buildings).
The evolution of the hurricanes is altered in some way by conditions other than SST (such as humidity) in the various models because the resulting intensity of the hurricanes seems to be shifted somewhat surprisingly by a constant amount across all SSTs according to Figure 11.
As with the intensity of hurricanes, that's a tough, if not impossible, call.
As we have discussed elsewhere on this site, statistical measures that focus on trends in the strongest category storms, maximum hurricane winds, and changes in minimum central pressures, suggest a systematic increase in the intensities of those storms that form.
Furthermore, the fact is (as shown in Figure 1) that hurricane intensity has increased in recent decades as SST has risen (at least in the North Atlantic for which trends are most reliable) and this prediction is based on fairly fundamental and robust thermodynamic arguments explored by Emanuel and others for decades now.
In a few short years, when the Arctic sea ice is totally absent during the summer months, and the water and air up there get hot (instead of being cold as it was during the past 10,000 years or more), we have no idea what is going to happen to the weather and that includes any attempt to predict intensities and frequencies of hurricanes, which, in my opinion, is a non sequitur.
Why is Katrina used as an example of hurricane intensity, when it was documented as only a Category 3 hurricane (albeit with a large storm surge)?
It's important to remember that in 2006, both sides in the hurricane - climate argument were awaiting Kossin's paper and saw it as a first attempt by a neutral arbiter to come in and reanalyze the global hurricane intensity data.
Which hurricanes we will reduce in intensity by our GHG reductions, we don't know, but since we care for all people, it doesn't matter which ones we help reduce, as long as we keep helping to reduce them.
The draft testimony says «Climate change is anticipated to alter the frequency, timing, intensity, and duration of extreme weather events, such as hurricanes and floods.»
As early as 1992 my Earth Day display on GW had a big hurricane on it, with mention of GW contributing to hurricane intensity AND frequencAs early as 1992 my Earth Day display on GW had a big hurricane on it, with mention of GW contributing to hurricane intensity AND frequencas 1992 my Earth Day display on GW had a big hurricane on it, with mention of GW contributing to hurricane intensity AND frequency.
Notably, issues such as why a given hurricane stalled or took a particular track (problems in dynamics) could not reliably be attributed to anthropogenic climate change, unlike intensity (which is clearly related to the thermodynamic state of the atmosphere and oceans).
In this context, I used Kossin's study as a peg to discuss just how contested the global hurricane intensity records remain, especially in basins other than the Atlantic.
And, as increase in ocean temperature lags increase in atmospheric temp., even if no AGW signal is yet visible in the hurricane data, this may not mean very much in terms of the future impact of AGW on hurricane intensity.
In following the course of projections for this storm, and then the burst of criticism about failed intensity forecasts, I was brought back to the hours I spent with meteorologists at the National Hurricane Center in September, 2004, as they tracked the course of Hurricane Ivan (shortly before I headed to Alabama to cover its landfall as a major hurricane; here's a narrated report I filed fromHurricane Center in September, 2004, as they tracked the course of Hurricane Ivan (shortly before I headed to Alabama to cover its landfall as a major hurricane; here's a narrated report I filed fromHurricane Ivan (shortly before I headed to Alabama to cover its landfall as a major hurricane; here's a narrated report I filed fromhurricane; here's a narrated report I filed from Mobile).
Furthermore, the paper clearly states that it doesn't address hurricane intensity, but only the landfalling hurricane record — and as others have noted the landfalling hurricane record doesn't really relate to the total hurricane frequency.
Don Keiller — as others have pointed out, that paper doesn't attempt to address the issue of the recent increase in Atlantic hurricane intensity, or the ongoing increasing trend of increasing sea surface temperatures and atmospheric moisture content.
