Sentences with phrase «between hurricane activity»

As we have also pointed out in previous posts, we can indeed draw some important conclusions about the links between hurricane activity and global warming in a statistical sense.

Not exact matches

Out of 58 hurricanes, 56 showed a significant correlation between lightning activity and wind speed, with peak winds arriving 30 hours after the lightning on average.

The researchers are not the first to examine a potential link between hurricanes and seismic activity.

The link between SSTs and hurricane activity is complex and subject to other variables such as the moisture content of the atmosphere (which is linked to SSTs) and wind shear aloft.

Emanuel found a close correlation between increases in this measure of hurricane activity (which is likely a better measure of the destructive potential of the storms than previously used measures) and rising tropical North Atlantic SST, consistent with basic theoretical expectations.

BTW, am I misremembering or has Emanuel said here for the first time that there's now a clear connection between global warming and hurricane activity (albeit not yet detectable in the North Atlantic basin when taken on its own)?

Just wondering, does the relationship between hurricane and cyclone activity and global warming have as good a correlation as between tree rings and instrumented temperature readings?

A good example of this was the recent post (s) here on the relation between hurricanes and AGW which elided Landsea and the earlier hurricane activity data.

But the new work did seem a lot more scientifically rigorous than most previous arguments against a link between global warming and hurricanes; which simply state we don't know enough about past hurricane activity to determine whether modern hurricane activity is unprecedented.

However, it don't agree that it is a definitive statement on the lack of a link between recent hurricane activity and anthropogenic global warming.

There is also strong disagreement between researchers over the accuracy of claims that hurricane activity has peaked over the past ten years.

OK, so apart from the Hockey stick graph, the disappearance of the Himalayan glaciers, the melting of summer Arctic sea ice, the lack of hurricane activity, the erroneous relationship between malaria and global warming, the resilience of corals, the obstinacy of Tuvalu and the Maldives to disappear to the sea, the manipulation of instrumental temperature data... (Gasp for breath!)

The activity focuses on six named hurricanes that occurred between 1999 and 2009.

... incomplete and misleading because it 1) omits any mention of several of the most important aspects of the potential relationships between hurricanes and global warming, including rainfall, sea level, and storm surge; 2) leaves the impression that there is no significant connection between recent climate change caused by human activities and hurricane characteristics and impacts; and 3) does not take full account of the significance of recently identified trends and variations in tropical storms in causing impacts as compared to increasing societal vulnerability.

The authors, from the Woods Hole Oceanographic Institution, say their findings do not necessarily conflict with recent papers asserting a link between the region's hurricane activity and human - caused warming of the climate and seas.

Don't forget that Judith Curry was one of the «scientists» claiming a connection between increased hurricane activity and global warming with less than adequate data (see discussions on this blog).

Detecting trends in Atlantic and eastern North Pacific hurricane activity is challenged by a lack of consistent historical data and limited understanding of all of the complex interactions between the atmosphere and ocean that influence hurricanes.4, 5,6

Over the past 50 years there has been a strong statistical connection between tropical Atlantic sea surface temperatures and Atlantic hurricane activity as measured by the Power Dissipation Index (which combines storm intensity, duration, and frequency).

One problem with the AMO idea is that despite the apparent relationship between oscillating sea temperatures, atmospheric changes and hurricane activity, scientists have yet to find an explanation in nature for why such a cycle would exist.

The hurricane signal shows strong, centennial - scale variations in frequency with a period of increased activity between the 12th — 16th centuries, and decreased activity during the 11th and 17th — 19th centuries.

The hurricane signal shows centennial - scale variations in frequency with a period of increased activity between the 12th — 16th centuries, and decreased activity during the 11th and 17th — 19th centuries.

Upon seeing efforts to establish relationships between various climate variables and NATL hurricane activity one is tempted to quote John von Neumann who said of fitting relationships with various parameters, «with four parameters I can fit an elephant, and with five I can make him wiggle his trunk» (as related in Dyson, 2004).

For a discussion of what can and can not be concluded about possible relationships between recent Hurricane activity and climate change, please see our post on Hurricanes and Global Warming: Is There a Connection?.

Therefore, we conclude that despite statistical correlations between SST and Atlantic hurricane activity in recent decades, it is premature to conclude that human activity — and particularly greenhouse warming — has already caused a detectable change in Atlantic hurricane activity.

If this statistical relation between tropical Atlantic SSTs and hurricane activity is used to infer future changes in Atlantic hurricane activity, the implications are sobering: the large increases in tropical Atlantic SSTs projected for the late 21st century would imply very substantial increases in hurricane destructive potential — roughly a 300 % increase in the PDI by 2100 (Figure 1a).

Using this additional downscaling step, the GFDL hurricane model reproduces some important historical characteristics of very intense Atlantic hurricanes, including the wind speed distribution and the change of this distribution between active and inactive decadal periods of hurricane activity (Fig. 1 of Bender et al. 2010).

Observed records of Atlantic hurricane activity show some correlation, on multi-year time - scales, between local tropical Atlantic sea surface temperatures (SSTs) and the Power Dissipation Index (PDI)-- see for example Fig. 3 on this EPA Climate Indicators site.

In fact, hurricane activity is more related to the difference in temperatures between the cold and warmer waters, a difference AGW theory says should decrease rather than increase.

Hurricane season runs from June through November, with a peak in activity between late August and October.
