Global warming may spur wind shear, sap hurricanes

All of you that live in hurricane areas should be hoping that global warming is real and do everything you can to promote it!!

MIAMI (Reuters) - Global warming could increase a climate phenomenon known as wind shear that inhibits Atlantic hurricanes, a potentially positive result of climate change, according to new research released on Tuesday.

The study, to be published on Wednesday in Geophysical Research Letters, found that climate model simulations show a "robust increase" in wind shear in the tropical Atlantic during the 21st century from global warming.

Wind shear, a difference in wind speed or direction at different altitudes, tends to tear apart tropical cyclones, preventing nascent ones from growing and already-formed hurricanes from becoming the monster storms that cause the most damage.

The effect of global warming on wind shear is similar to the impact of El Nino, the periodic eastern Pacific warm-water phenomenon that tends to put a damper on Atlantic storms. The sudden development of El Nino was credited for an unexpectedly mild Atlantic season last year, when only 10 storms formed.

Debate on the likelihood that human-generated climate change contributes to hurricane development has raged since the 2005 Atlantic season, which produced a record-shattering 28 tropical storms and hurricanes.

That season saw some of the most powerful hurricanes in history and produced Katrina, which killed 1,500 people and caused $80 billion damage on the U.S. Gulf Coast. The hurricane threat roiled global oil and gas markets.

HEATING UP SEA WATER

In recent years some scientists have suggested that human-induced greenhouse warming may be increasing the intensity of Atlantic hurricanes by heating up the sea water from which they draw their energy.

In February a report by the Intergovernmental Panel on Climate Change said it was "more likely than not" that humans contribute to a trend of increasingly intense hurricanes.

But researchers in the new study said increased wind shear could counter the effect of warming waters in the Atlantic.

"The environmental changes found in the study do not suggest a big increase in tropical Atlantic hurricane activity during the 21st century," said Brian Soden, a co-author of the report.

The increase in wind shear was only seen in the Atlantic and eastern Pacific. In the western Pacific, global warming appeared to cause both increased water temperatures and a reduction in wind shear, Soden said.

The study, by scientists at the University of Miami's Rosenstiel School and a National Oceanic and Atmospheric Administration lab in Princeton, New Jersey, is the first to identify changes in wind shear that could counteract the other impacts of global warming on hurricanes, the researchers said.

Soden said as the climate warms, atmospheric circulation tends to weaken and upper level westerlies shift further eastward into the Atlantic, increasing wind shear there. The effect is similar to an El Nino impact.

"The difference is that El Nino is a natural cycle, whereas the results from global warming are much smaller year-to-year but they accumulate over time," he said.

Hurricane researchers believe the Atlantic-Caribbean hurricane zone is in a period of heightened activity that began around 1995 and could last between 25 and 40 years.

This is just a study. Hasn't been verified yet.

Same goes for man made global warming.

The climate chicken littles say:

-there will be more hurricanes

-there will be fewer hurricanes

-there will be worse hurricanes

-there will be milder hurricanes

-there will be colder weather

-there will be warmer weather

With predictions like that they can't miss!!!!

But the truth is that THE CLIMATE HAS NEVER BEEN THE SAME BUT THESE ARROGANT CHOPF#CKS THINK IT SHOULD NOT CHANGE NOW THAT HUMANS ARE HERE. NIMBY on a global scale.

Hey Gary, I've seen a lot of posts with you and other guys criticizing global warming theories, and all the measures we can take to stop pollution, and the carbon monoxide thing, etc etc.. even if it's a non-proved study, what is the problem with all the measures some people are proposing? like becoming more eco-friendly, energy efficient houses, save the trees, all the enviro-friendly shabang.. is it that u dont want govt environment control? or u don't want Al Gore telling us how to control the emissions while he has a huge house and spends a lot of money in energy? or the celebrities being all cool with hybrid vehicles while they spend a lot of gas flying their private jets?

I mean, even if global warming caused by humans is a lie, what's wrong with some of the measures they propose? I don't think doing them would harm the planet, or kill more trees.. wouldn't it be better to do it, just in case?

They have a super computer in Korea called the NEC Earth Simulator. It's the most powerful weather predicting computer ever, however, it's still weak because it's slow to calculate the exact weather conditions.

I'm going to help build a computer that take the solar activity of the sun, moon phase, ozone, jet stream, ocean currents using quantum computers with a ridiculous amount of floating point units to better predict the weather. To more closely predict the outcome of the weather is to monitor every single unit of atom. One atom can interact with another creating a chain reaction that is predictable given a more accurate computer.

Banks are using quantum algorithm in their security protocols for ATM and computers.

Well, don't just post it ! Give yourself a big kiss and a new engagement ring and a torrent of hot promises about how you'll never be ordinary again.

thanks brother

Also, I'm 100% for less pollution, cleaner rivers, air etc.... But it should be done because it's the right thing to do not because some slick politician profiting from selling 'carbon credits' says to do it.

How about this... I'm going to sell "Bullsh!t Credits". Just send me $10 for every 100 words of BS anyone wants to spew.

I have always been in favor of less pollution. By all means preserve our natural habitats and our environment. But this GW sh!t is about CO2. It isn't a pollutant. If it were every living thing is polluting every time it breaths out. Some of the things the GW nuts put forward will not change anything but will hurt our economy. I see this for what it is. A power play by the anti-capitalists. They want to control the large countries economies and this is their battle cry.
