Hurricane Wilma kwam/ komt in aanmerking. Als ik me niet vergis, hurricane Wilma was category 6.

Echter, categorie 6 bestond toen niet.

Misschien moeten we de vraag stellen, is categorie 7 mogelijk?

op andere planeten zijn genoeg stormen die voor categorie 7 tot 10 in aanmerking komen... misschien kunnen we d'r eentje mee jatten

En we kunnen nu officieel melden dat het ' Amerikaanse ' Stormenseizoen nu echt is begonnen met de eerste storm van het seizoen: ALETTA is een feit.
Weliswaar zit deze storm aan de Pacifische kant van de VS, maar het is en blijft de eerste storm van het seizoen en dat al voor 1 juni...



MEXICO CITY — Aletta became the first tropical storm of the season in the eastern Pacific on Saturday when it formed about 100 miles south of the Mexican coastal resort of Acapulco.

Forecasters predicted it would head toward land but later change direction, skirt the coast and head out to sea.

Mexico issued a tropical storm watch for a 240-mile stretch of coast from Punta Maldonado to Zihuatanejo, the U.S. National Hurricane Center in Miami reported.

Tropical Storm Aletta had winds of about 40 mph and was expected to reach wind speeds as high as 60 mph. Forecasters were predicting heavy rainfall to the Mexican coast.

The storm was moving north at about 7 mph, but forecasters did not expect it to reach the coast before turning back out to sea.

Niet zeuren ik wil wel een cat 6 mee maken

jij hoort sinds 16-02-2006 een orkaan van 6e categorie mee te maken in bed

Hier nog een opmerking die ik van Amerikaanse nieuwssites haalde

Zelfs de Amerikanen schenken ineens massale aandacht aan ons kleine landje na een opmerking over de zeespiegelstijging van ca 14 inch in 2050 (ca 35 cm)
=======================

THE HAGUE, Netherlands — The Dutch can expect wetter winters and a threatening rise in sea levels of up to 14 inches by 2050, said a report Tuesday by the National Weather Service.

While many countries discuss global warming and greenhouse gas emissions as theories, the Dutch see climate change as a matter of survival demanding concrete action.

"Sixty percent of our country lies beneath sea level, so the effect of a rise in the level of the oceans is very noticeable," said Melanie Schultz van Haegen, the secretary of transport and water, after receiving the report from the Royal Dutch Meteorological Institute known by its Dutch acronym KNMI.

But she said there was "no acute danger" to the country's sea defenses, which are among the best in the world.

The Dutch earmark more than $1.2 billion annually — around 1 percent of the national budget — to maintain and improve the dikes, dunes, pumps, sluices and windmills that work constantly to keep the country dry.

Those defenses must take into account the consequences of global warming, but Schultz van Haegen said it could be done within existing spending plans


KNMI put forward a range of scenarios it thought were strong enough to base policy on, using measurements and modeling by its own scientists as well as the most recent international studies.

It predicted an increase in average temperature in the Netherlands of at 1.8 degrees to 3.6 degrees by 2050, compared with 1990, and a rise in sea level by 6 inches to 14 inches.

"If you plan a children's birthday party in the Netherlands in July, you know it can be great weather, but you can also have a cloudburst. If you're prudent, you're prepared for both scenarios," said KNMI climate expert Gerbrand Komen, presenting the findings. "It can also snow in July, but you don't really need to plan for it," he said.

The report says rainfall will likely increase by 4-14 percent in the winter, and intense cloudbursts will become more common in the summer. But scientists cannot predict whether overall summer rain will decrease or increase, he said.

The history of the Netherlands, whose very name means "the low-lying countries," has been shaped by its struggle to cope with excess water, beginning before Roman times. The country's economic heart lies in the delta where the Rhine and Maas rivers meet the North Sea.

Since a 1953 flood that killed 1,800 people, sea defenses have been engineered to withstand any storm but the biggest predicted once every 10,000 years. River dikes are supposed to hold against a sustained rainfall statistically likely every 250 years.

By comparison, New Orleans' levies were designed against storms up to those likely to occur once in 100 years.

But even with global warming, the North Sea is not expected to generate storms the size or intensity of Hurricane Katrina.

Schultz van Haegen said she expected the European Union to agree on flood cooperation guidelines in July.

"Problems can't be pushed off on lower-lying countries, but each country must undertake a package of measures to take care of rain that falls in its borders," she said.

In April, the Dutch government said it expected to meet its Kyoto Protocol targets for reducing carbon dioxide emissions. Under the treaty, the Netherlands must cut greenhouse gas output 6 percent by 2012, from 1990 levels

Study: Hurricanes go stronger due to Human Pollution

FORT COLLINS, Colo. — Kerry Emanuel sparked a debate among his colleagues last year when he published a paper that linked global warming to the trend of increasingly stronger Atlantic Ocean hurricanes observed in recent decades.

In a study to be published soon, the Massachusetts Institute of Technology climatologist will make another bold claim: The cycling of hurricane activity from high to low, which some scientists have attributed to a natural cycle in global weather patterns, is in fact caused by the rise and fall of pollution released by humans.

Furthermore, Emanuel, along with Michael Mann of Pennsylvania State University, contend that the microscopic aerosol particles, which reflect sunlight and cool the atmosphere, have been masking the effect of global warming on Atlantic Ocean hurricanes for several decades. The researchers say that it is only in recent decades, as aerosol emissions from North America and Europe have declined due to clean air standards, that the full impact of greenhouse gas emissions on hurricane strength has been realized.

Meanwhile, other new research by Purdue University scientists supports Emanuel’s original finding and extends it to the entire globe.

Together, the two new studies suggest that hurricanes, known as cyclones elsewhere, are getting stronger all over the planet and that humans play a role in the change

Stronger cyclones worldwide

Research done by Matthew Huber and Ryan Sriver at Purdue University in Indiana independently verifies and expands upon Emanuel’s 2005 study, which showed that hurricanes in the Atlantic and Pacific Oceans had increased in duration and intensity by about 50 percent since the 1970s. Emanuel linked the trend to rising sea surface temperatures, or SSTs, caused in part by global warming.

"We used a different technique and different data than Dr. Emanuel, who looked specifically at the Atlantic and western Pacific oceans, whereas we looked at the entire world," Huber said. "Nevertheless, we got the same results that he did, the same basic trends."

The researchers used surface wind and temperature records from the European Centre for Medium-Range Weather Forecasts 40 Year Reanalysis Project to estimate the total wind output of tropical cyclones worldwide from 1958 to 2001. Called the "globally integrated tropical cyclone power dissipation," this value represents the potential damage that a storm can cause.

The Purdue study marks the first time this value has been calculated on a global scale. It found that tropical cyclone activity has doubled over the past 40 years with only a quarter degree Celsius of tropical ocean warming. This is cause for concern, the researchers say, because scientists expect a two-degree warming over the course of the next century.

"The signal that we looked at is a measure of not only the intensity but also the duration of the storm," Sriver told LiveScience. "What we've seen is an increase in strength and duration but not necessarily in the number of storms."
