Global warming may spur wind shear, sap hurricanes
| Quote From Source: | 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.

I wonder if this is a poor attempt to C.Y.A. (cover your a$$)after last year. They have already said this is going to be a very busy hurricane season, but what if it isnt? Well now they have an excuse before the season starts. Last year they blamed it on dust from Africa. This year it will be wind sheer apparently.
But what if there are lots of hurricanes? Does that mean there was no global warming to create the wind sheer? Or will it be global warming that caused the hurricanes? Do they even know?
Global warming is bullshit yet they are going on like it is so real and coming up with crap like this saying what it can and cannot do. Oh lets look at the plus side!! Oh no, look at the negative side!! Give me a break. There is absolutley no friggen way in hell, or on earth, that they can even guess how many hurricanes there are going to be, this year or 20 years from now.
They should take the warning labels off of everything and let stupidity sort itself out.

well like you said, they can't figure out what next week will be like...
how the hell can they guess 20 years ahead?
tell ya one thing, it's gonna be a wild ride.

i think this is good, to see all these studies comming out. even ones that show positives of 'global warming'
might be a small step for certain research groups to man up and put out anti-global warming studies. i'm sure they're out there gathering dust. |

I think we are about ready to into another ice age in the next 50 yers, so they should be working on research into how hurricane activity was during the last ice age. |

I think the nature of the storms will change. I think your coastal storms and storms originating in the south will be much larger.

Now that I get thinking about it, a ice age would likely force the line of storm formation to the south. Why because the glaciers are very cold, then you have a warmer tropics which at the edge of the glaciers line about 30-45 north will be the storm area all year around. Instead of 45 during winter and 55 durning Summerl. So that would mean more shear because hurricanes form in area's of little to no shear. So less hurricanes.
The jet stream forms based on temperature differences that is why storms normally form(Extratropical) at 45-60 north. But with a ice age that would push to 30-40 north. But I think what this study is point out is the fact that the "tutt" over the western Caribbean would in fact get stronger. But on the other hand the jet stream with a warming world would get weaker. So less shear away from the tutt. |

My reasoning was a little different. My thinking is that with a failed gulf stream you'll likely get a warmer Gulf of Mexico. Southern tracking storms tend to be bad as it is. Imagine having more fuel to work with from the gulf and colder air to pull in from the north. Imagine something greater than the March storm of 1993 taking 3 days to move out. It would be a disaster of catastrophic proportions. You'd have several feet of snow covering many states and thousands of buildings collapsing under the weight of the snow. Emergency services would be impossible for weeks. People would literally begin starving in their own homes if they weren't prepared. And I don't think this type of storm is that far out in left field. I think we will have it in our lifetimes.

The Super storm of 93 was a extratropical cyclone, it feeds off temperature differences across wide area's. So cold to the north and west, and warm and humid to the south and east of the system. A ice age would become more faverable for systems like it to form. I do mean that 93 like storms could become very very normal. On the other hand a tropical cyclone is a warm core system, what it needs is very low wind shear; 'winds at all levels near the same'. With a jet stream which is stronger in more southward into the tropics you will have much higher wind shear. Also the fact that the oceans could be a good amount colder to.
Also a a troical cyclone of any kind needs humid moist at all levels. Cold air would mean less moisture for the tropical cyclone, see one reason cyclones weaken as they are moving at large land masses is just that. They suck much drier air into there cores. So yes there is a lot of factors that would make tropical cyclones durning a ice age much less possible.
On the other hand stronger Extratropical systems would become monsters from the depth of of the underworld.
A cyclone takes its energy from the ocean,,,but also strengthens based on height temperatures differences.
If the gulf stream slowed down or stopped, more warm water would stay over the southern part of the North Atlatnic,,,In maybe less powerful storms forming over the northern Atlatnic, which would decrease upper level wind shear. But a ice age another story all together. |
