Storms Vary With Cycles, Experts Say
By KENNETH CHANG
Published: August 30, 2005
Because hurricanes form over warm ocean water, it is easy to assume that 
the recent rise in their number and ferocity is because of global warming.
But that is not the case, scientists say. Instead, the severity of 
hurricane seasons changes with cycles of temperatures of several decades 
in the Atlantic Ocean. The recent onslaught "is very much natural," said 
William M. Gray, a professor of atmospheric science at Colorado State 
University who issues forecasts for the hurricane season.

Una cosa non esclude l'altra.Il Dr. Gray sara' uno dei tanti scienziati 
reazionari che  piacciono a Bush.
Sei pagato anche tu dalla Halliburton o metti il cervello all'ammasso gratis?
Am.

o metti il cervello all'ammasso gratis?
...disse il povero *FESSO MONONEURONE*... :)

 c'entra quella parte con la stronzata che hai appena scritto? :)
Volentieri. Ma fai conto che non proseguo la conversazione su un tono 
maleducato.
Il Dr. Gray e' un metereologo, incaricato di fare previsioni 
metereologiche in tempi relativamente brevi. Puo' quindi permettersi di 
ignorare un trend secolare di riscaldamento globale.
Sono gli scienziati che si occupano di quest'ultimo a sostenere che gli 
uragani vanno acquistando che gli uragani vanno acquistando forza e/o 
frequenza.
Non vi e' univocita' in materia, ma direi che con Kyoto la 
*maggioranza* degli scienziati ha espresso preoccupazione per la 
moltiplicazione di eventi estremi dovuti al riscaldamento globale.
Questo non vuol dire che non esistano scienziati legati ad una 
fondazione finanziata dai petrolieri americani che sostengono l'opposto.

moltiplicazione di eventi estremi dovuti al riscaldamento globale.
Prove di questa fantasiosa "moltiplicazione di eventi estremi dovuti al
riscaldamento globale"? :)

 fondazione finanziata dai petrolieri americani che sostengono l'opposto.
Mentre altri scienziati, con interessi politici/di carriera differenti 
sostengono la causa opposta.
La realtà è che se uno canta fuori dal coro, in ambiente accademico, 
rischia la carriera e di non lavorare più.

No: lo dicono parecchi esperti. Guarda l'articolo in calce, eppoi dai 
un'occhiata al rapporto del Pentagono in PDF, qui:

Buona lettura a tutti voi.

Global warming 'has doubled storm threat'
Weather expert finds destructive power worse than models predict
Paul Brown, environment correspondent
Friday August 26, 2005
The Guardian
Tropical storms have doubled in destructive potential in the past 30 
years because ocean surfaces have become warmer, according to a leading 
climate researcher.
This is the first time that an increase in the size, duration and power 
of tropical storms has been linked to global warming.
The result could have a significant effect on British weather, and have 
potentially disastrous consequences for the Caribbean, the west coast 
of the United States and Pacific countries such as Japan.
 Professor Kerry Emanuel, of the atmospheric, oceans and climate 
research department at the Massachusetts Institute of Technology, has 
studied data from all the severe storms - or tropical cyclones - over 
the past 30 years.
He says they have been more intense and longer in duration, and have 
generated far more power, than computer models had predicted. Prof 
Emanuel, an acknowledged world expert on the thermodynamics of tropical 
cyclone research, told the Guardian he believed the power of the storms 
to create huge waves and mix the surface water of the oceans could also 
effect ocean currents - particularly the Gulf Stream, which sends warm 
water northwards and keeps Britain's climate milder than it otherwise 
would be.
Many scientists have predicted that the Gulf Stream could slow or be 
"turned off" by the effect of increased fresh water entering the Arctic 
from melting ice.
But Prof Emanuel believes that the greater mixing of warm water in the 
tropics could have the opposite effect - speeding up the currents and 
driving more warm water north.
Although there is no connection between his research and recent 
observations in Iceland, temperatures in the North Atlantic have risen 
notably as as a direct result of a strong current flow pushing farther 
north.
Prof Emanuel's findings, published in Nature magazine, follow an 
inconclusive scientific debate about whether the frequency of storms is 
a natural phenomenon or a result of man-made climate change.
Climate models run through computers indicate that storms are likely to 
become more severe, but this is the first evidence that this is already 
happening. What is surprising is that the severity is far more 
pronounced than the computer models predicted.
According to the paper, the computer models estimated that wind speeds 
would increase by 2 to 3% as a result of an already observed rise in 
the ocean temperature of .5C. Because of the longer duration of storms, 
this would increase the total force exerted by the average hurricane by 
8 to 12%.
However, Prof Emanuel's measurements of real winds show that storms can 
pick up much greater intensity as the ocean waters mix.
During a storm, the winds cause the warm surface water to mix with the 
cooler ocean below. Normally, this mixing would puts a brake on the 
power of the storm because of the overall reduction in sea temperature 
caused by the mixing. But measurements show that it is not just the 
surface of the sea that has warmed in recent decades - the layer 
underneath is also at a higher temperature.
This means the wave action that mixes the layers does not have such a 
pronounced cooling effect as before and, as a result, the intensity of 
the storm remains significantly higher.
Prof Emanuel's view is that at least part of this increase in ocean 
temperature is caused by man-made climate change.
"Whatever the cause, the near doubling of power dissipation over the 
period of record should be a matter of some concern, as it is a measure 
of the destructive potential of tropical cyclones."
Julian Heming, a tropical prediction scientist with the Met Office in 
Exeter, said he did not question Prof Emanuel's measurements, but 
pointed out that there was disagreement among scientists about whether 
the observed trend was man-made or part of a natural cycle.

power of tropical storms has been linked to global warming.

Svegliati un po'  De Cesari. Sarebbe bello se le cose rimanessero 
sempre uguali nell'Italietta della siesta, e nel Texas Lone Star, ma 
cosi' non e'.
Come il prezzo del petrolio e i fenomeni estremi. Non robe che si 
risolvono con l'ordine pubblico e gli M 16.
Am.
PS: Castagno c'hai la tromba della sveglia oltre a quella del silenzio? 
Sempre molto grato.

Come il prezzo del petrolio e i fenomeni estremi.
E ca**o c'entra il prezzo del petrolio lo sai solo tu :)
Quanto ai "fenomeni estremi" chissa' perche' non sei riuscito ancora ad
elencarli.
