Not exact matches

For example, when examining hurricanes and typhoons, the lack of a high - quality, long - term historical record, uncertainty regarding the impact of climate change on storm frequency and inability to accurately simulate these storms in most global climate models raises significant challenges when attributing assessing the impact of climate change on any single storm.

Whenever they found large dips in the oxygen - 18 isotope, they found a corresponding historical record of a hurricane.

They also make an important point: historical records of hurricane intensity are of no value prior to 1945 or so:

And we could say this because we had historical records for hurricanes and ocean temperatures, as well as other studies of proxy records of temperatures, suggesting that these busy and quiet periods tend to last 25 to 40 years each.

Historical records indicate that moderate to strong El Nino events dampen hurricane activity — whereas years with very weak El Niño conditions can be associated with active hurricane seasons if a Climate Pulse Hurricane Enhancement Cycle is in place — and it ihurricane activity — whereas years with very weak El Niño conditions can be associated with active hurricane seasons if a Climate Pulse Hurricane Enhancement Cycle is in place — and it ihurricane seasons if a Climate Pulse Hurricane Enhancement Cycle is in place — and it iHurricane Enhancement Cycle is in place — and it is.»

This uses the historical record (such as reanalyses) to introduce many more plausible landfalling hurricanes than actually occurred, in order to assess better risk.

In 2007 Michael Mann and colleagues published a paper (PDF) critical of work suggesting an undercount in storms from historical records, claiming that it was «perilous» to assume that there is a «fixed» relationship between landfalling and total hurricanes in the Atlantic basin:

While scientist may struggle to agree on whether there is a discernible pattern of increased hurricane activity in the historical records, most are agreed that global warming will make hurricanes bigger and wetter.

«The North Atlantic hurricanes deserve special discussion in light of the relatively long historical record of hurricanes.

To try to gain insight on this question, we have first attempted to go beyond the ~ 50 year historical record of Atlantic hurricanes and SST to examine even longer records of Atlantic tropical storm activity and second to examine dynamical models of Atlantic hurricane activity under global warming conditions.

While the earlier study was based entirely on historical records of past hurricanes, showing nearly a doubling in the intensity of Atlantic storms over the last 30 years, the new work is purely theoretical.

In short, the historical Atlantic hurricane record does not provide compelling evidence for a substantial greenhouse warming - induced long - term increase.

In this article, I will review our current understanding of Atlantic TC and hurricane trends with respect to: A) the historical record of basin - wide TC numbers; B) the historical record of hurricanes and TC intensity; C) distant past proxy estimates of TC (primarily, hurricane only) counts; and D) distant past proxy measures of TC / hurricane intensity.

In a section on how the frequency of hurricanes and cyclones is likely to change, the report cites what's been called a «hurricane drought» — a remarkable gap, «unprecedented in the historical records dating back to the mid-19th century» — in the U.S. being hit by storms category 3 or higher.
