Sentences with phrase «hurricane intensity which»

The logic makes sense (increased SST's increase hurricane intensity which increases damages from any given storm), but logic is not the same as scientific evidence.

Gore indicated that it is primarily Hurricane intensities which scientists largely agree should be expected to increase in association with warming surface temperatures, and specifically notes that

Not exact matches

The intensity of Hurricane Maria, which made landfall on Puerto Rico as a Category 4 storm on September 20, was part of why it was so devastating to the island and its weak infrastructure, leaving Puerto Ricans in a humanitarian crisis.

«You can in fact reduce the upper ocean [temperature] by a degree Celsius, maybe 2, which would have a measurable effect on the intensity of the hurricane, but the practical concerns were hard to overcome.»

The best historical analogue for a hurricane that follows NHC's 5 pm EDT Friday track and intensity forecast for Irma may be Hurricane Donna of 1960, which tore through the Florida Keys just northeast of Marathon as a Category 4 storm with 140 mhurricane that follows NHC's 5 pm EDT Friday track and intensity forecast for Irma may be Hurricane Donna of 1960, which tore through the Florida Keys just northeast of Marathon as a Category 4 storm with 140 mHurricane Donna of 1960, which tore through the Florida Keys just northeast of Marathon as a Category 4 storm with 140 mph winds.

There are so many more hurricanes, tornados, famine, simonies, floods, and so on which are increasing continually and with more intensity.

But a reduction in the number and intensity of large hurricanes driving ocean waters on shore — such as this month's Hurricane Joaquin, seen, which reached category 4 strength — may also play a role by cooling sea - surface temperatures that fuel the growth of these monster storms, the team notes.

But last year, the team was able to improve the resolution on its hurricane model, which helped improve the intensity predictions.

The Hurricane Forecast Improvement Project (HFIP), which began in 2009, is an effort to improve the service's ability to forecast hurricane tracks and intensity further inHurricane Forecast Improvement Project (HFIP), which began in 2009, is an effort to improve the service's ability to forecast hurricane tracks and intensity further inhurricane tracks and intensity further in advance.

With respect to 181, if global warming increases sea surface temperatures which contribute to an intensification of tropical cyclones, then storms with winds below hurricane intensity will more frequently attain hurricane status (~ 100 kph winds).

Here is an example of a changing entropy pattern, just like the increase in hurricane intensity, brought about by microphysics changes which have occurred due directly to increases of CO2 changing the CONDUCTIVITY of oceans.

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.

«The IPCC Summary notes that there is evidence for increased hurricane intensity in the North Atlantic, which is correlated with higher sea surface temperatures.

What most people seem to forget here, is that on one hand there are fundamental thermodynamical arguments which demand that hurricane intensity increase over time, while on the other hand, there are these two big chunks of ice sitting in both polar regions, which will counteract the warming process in their own special way.

One thing which seems to be missing from the discussion is not whether or not hurricanes will increase in intensity and become more frequent but whether we will begin to see more storms make landfall in places that didn't historically get these kinds of events.

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 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 which ones we help reduce, as long as we keep helping to reduce them.

Some people have suggested that if SST (& GW) is increasing hurricane intensity, it seems logical it would also be increasing hurricane frequency (all other things being equal — which I suppose they may not be), since the storms are moving up in category: 1 to 2, 2 to 3, etc., then some «tropical storms» would also be moving up to Cat.

This is the foundation of the Dvorak Enhanced Infrared (EIR) technique [Dvorak, 1984], which is utilized by all tropical forecast offices in every ocean basin to estimate hurricane intensity with geostationary infrared imagery.

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).

Perhaps the Trenberth Press Conference in which the connection of hurricane frequency and intensity to GW was affirmed is an example of «alarmism».

I thought of some way in which you could get more intensity, without increased frequency: Perhaps hurricanes & tropical storms are clubbing together into more intense storms (what would have been 2 hurricanes given lower SST, become 1 more intense hurricane, given the higher SST).

This result is similar to that which is reported in Webster et al. (2005), where they find: «This increase in category 4 and 5 hurricanes has not been accompanied by an increase in the actual intensity of the most intense hurricanes.

Based on the results of the causality tests, the author concludes that it is global near - surface air temperature that influences sea surface temperature, and not the other way around — which supports the global warming - induced increase in hurricane intensity.

While many studies of the effects of global warming on hurricanes predict an increase in various metrics of Atlantic basin - wide activity, it is less clear that this signal will emerge from background noise in measures of hurricane damage, which depend largely on rare, high - intensity landfalling events and are thus highly volatile compared to basin - wide storm metrics.

So, on the one hand you have the claim that Atlantic hurricane intensity is controlled by the AMO, whose mechanism is poorly understood but which has something to do with the meridional overturning circulation, which is influenced by the sinking of water off of Greenland.

-- Increases in intensity and frequency of heat waves and extreme precipitation events (a category in which it includes droughts, floods, hurricanes and major storms)

In particular, their claim that hurricane activity (which seems to be a poorly defined phrase — does it mean frequency + intensity?)

In 2005, Emanuel reported that hurricane intensity, which is fed by warmth, had increased some 80 percent during the previous 50 years, a period during which temperatures had increased more dramatically than any time in at least 500 years.

If so, this is one way in which global warming may end up causing a decrease in Atlantic hurricane activity over the coming decades, since the increased wind shear over the Atlantic during El Niño events greatly reduces the number and intensity of these storms.»

There has been a substantial increase in most measures of Atlantic hurricane activity since the early 1980s, the period during which high quality satellite data are available.20, 21,22 These include measures of intensity, frequency, and duration as well as the number of strongest (Category 4 and 5) storms.

The colour field underneath the wind arrows shows the precipitation rate on a scale from 0 to 20 mm per hour, noting that peaks in rainfall intensity (which may have been far higher than 20 mm / hr at times in localised regions within the Hurricane circulation), are not resolved in this animation.

Not quite correct i'm afraid (though nearly right)-- there has been no observable increase in the frequency of storms (though, to be accurate, the research which forms the basis for this statement was actually focused on subject of hurricanes, not storms per se) but there has been substantial increase in their intensity — particularly in US — Hurricanes Sandy & Katrina ring any bells?

The intensity of Hurricane Maria, which made landfall on Puerto Rico as a Category 4 storm on September 20, was part of why it was so devastating to the island and its weak infrastructure, leaving Puerto Ricans in a humanitarian crisis.

Global warming also increases both the risk and intensity of hurricanes — which are dependent on sea surface temperatures — and the hazards of flooding, because global warming is linked to sea level rise.

There has been a substantial increase in most measures of Atlantic hurricane activity since the early 1980s, the period during which high - quality satellite data are available.13, 14,15,16,17 These include measures of intensity, frequency, and duration as well as the number of strongest (Category 4 and 5) storms.

This, says Crompton, should not be surprising as there has been no observed increase in hurricane frequency and intensity at landfall over the period for which normalization data is available.

Rising ocean temperatures have shifted the intensity of tropical cyclones, which include hurricanes and typhoons, to higher levels.

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).

However, the IPCC claims all ilk of adverse effect (extreme temperature, increased drought, increased flooding, increased hurricane intensity, etc.), none of which are corroborated.

This coupling of the atmosphere with the ocean enables the model to reproduce the cooling of the ocean surface beneath the hurricane, which has an important impact on hurricane intensity.

Such precautions are still necessary say the scientists who caution that their study only looked at the tracking patterns of hurricanes — and not their frequency and intensity which are expected to increase.

Part I Re # 62 and # 61; Those issues relate back to the AMO's quite questionable role in Atlantic hurricane intensity / frequency and Landsea et al's oblique attack on the more recent hurricane intensity data in Science which Chuck Booth links to.

With regards to their statements that the global data can not be trusted since they don't agree with climate model results (which suggest a smaller increase in hurricane intensity).

Regarding your blog entry on the V+S paper, one statement needs clarification: ``... 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.»

Towards the end of his presentation he added: «Some research suggests global warming is linked to rising ocean and sea surface temperatures in the tropical Atlantic and the Gulf of Mexico — which may have an impact on hurricane intensity.

# 207, so what I gain from your piece is that Katrina & Rita are well within «normal» & not as bad as the worst — which means to me as a Rio Grande Valley resident, I have some extraordinarily big, perhaps Cat 6 hurricanes to worry about in the future with GW enhanced hurricane intensity.

It is important to stress that there are many factors which impact hurricanes, and NOAA supports and values a wide variety of research which will help to identify those factors and theirimpact on hurricane frequency and / or intensity.»

RE # 193 my legal understanding (as a layperson) would be that we can not make a criminal case re the link between CC & hurricane intensity of a specific hurricane, which requires «beyond a resonable doubt» (sort of like a scientific standard of p <.05), but there could be a civil case, which requires a «preponderance of evidence.»

The models heavily relied upon by the Intergovernmental Panel on Climate Change (IPCC) had not projected this multidecadal stasis in «global warming»; nor (until trained ex post facto) the fall in TS from 1940 - 1975; nor 50 years» cooling in Antarctica (Doran et al., 2002) and the Arctic (Soon, 2005); nor the absence of ocean warming since 2003 (Lyman et al., 2006; Gouretski & Koltermann, 2007); nor the onset, duration, or intensity of the Madden - Julian intraseasonal oscillation, the Quasi-Biennial Oscillation in the tropical stratosphere, El Nino / La Nina oscillations, the Atlantic Multidecadal Oscillation, or the Pacific Decadal Oscillation that has recently transited from its warming to its cooling phase (oceanic oscillations which, on their own, may account for all of the observed warmings and coolings over the past half - century: Tsoniset al., 2007); nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age; nor the cessation since 2000 of the previously - observed growth in atmospheric methane concentration (IPCC, 2007); nor the active 2004 hurricane season; nor the inactive subsequent seasons; nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously); nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solankiet al., 2005); nor the consequent surface «global warming» on Mars, Jupiter, Neptune's largest moon, and even distant Pluto; nor the eerily - continuing 2006 solar minimum; nor the consequent, precipitate decline of ~ 0.8 °C in TS from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.
