Cooling Pacific Heralds Active Atlantic Hurricane Season

Cooling Pacific Heralds Active Atlantic Hurricane Season

CAMP SPRINGS, Maryland, March 9, 2007 (ENS) - On the heels of El Niño, its opposite, the cooling weather pattern in the east-central equatorial Pacific known as La Niña is expected to arrive soon, according to government forecasters. La Niña conditions in the Pacific typically mean a greater than normal number of Atlantic hurricanes.

In a weekly update, scientists at the NOAA Climate Prediction Center said that as the 2006-2007 El Niño has faded, surface and subsurface ocean temperatures have rapidly decreased.

Recently, cooler than normal water temperatures have developed at the surface in the east-central equatorial Pacific, indicating a possible transition to La Niña conditions.

These changes affect tropical rainfall patterns and atmospheric winds over the Pacific Ocean, which influence the patterns of rainfall and temperatures in many areas worldwide. Typically, across the United States during the spring and summer months, La Niña conditions do not significantly impact overall inland temperature and precipitation patterns,but La Niña episodes often do have an effect on Atlantic and Pacific hurricane activity.

"Although other scientific factors affect the frequency of hurricanes, there tends to be a greater than normal number of Atlantic hurricanes and fewer than normal number of eastern Pacific hurricanes during La Niña events," said NOAA Administrator Conrad Lautenbacher.

"During the winter, usual La Niña impacts include drier and warmer than average conditions over the southern United States," he said.

"NOAA's ability to detect and monitor the formation, duration and strength of El Niño and La Niña events is enhanced by continuous improvements in satellite and buoy observations in the equatorial Pacific," Lautenbacher explained.

The observing systems currently at work include the TAO/TRITON moored and Argo drift buoys, as well as NOAA's polar orbiting satellites.

"La Niña events sometimes follow on the heels of El Niño conditions," said Vernon Kousky, research meteorologist at the NOAA Climate Prediction Center. "It is a naturally occurring phenomenon that can last up to three years."

"While the status of El Niño/La Niña is of vital importance to our seasonal forecasts, it is but one measure we use when making actual temperature and precipitation forecasts," said Kousky.

La Niña episodes tend to develop during the four months from March through June, reach peak intensity during the December to February period, and then weaken during the following March to May period.

"The last lengthy La Niña event was 1998-2001, which contributed to serious drought conditions in many sections of the western United States," said Douglas Lecomte, drought specialist at the NOAA Climate Prediction Center.

In addition, atmospheric scientists have uncovered fresh evidence to support the controversial theory that global warming has contributed to the emergence of stronger hurricanes in the Atlantic Ocean. Scientists at the University of Wisconsin-Madison and NOAA's National Climatic Data Center report that all the physical variables that converge to form hurricanes - wind speeds, wind directions and temperatures - feed off each other in ways that only make conditions more ripe for a storm.

The unsettling trend is confined to the Atlantic and does not hold up in any of the world's other oceans, researchers have also found.

James Kossin, a research scientist at UW-Madison's Cooperative Institute for Meteorological Satellite Studies, says the pattern emerged from a new dataset that correlates a variety of different satellite data over 22 years from 1983 to 2005.

"While we can see a correlation between global warming and hurricane strength, we still need to understand exactly why the Atlantic is reacting to warmer temperatures in this way, and that is much more difficult to do," says Kossin. "We need to be creating models and simulations to understand what is really happening here."

NOAA will issue the U.S. Spring Outlook on March 15, and its Atlantic Hurricane Season Outlook in May. Both outlooks will reflect the most current La Niña forecast.

Wait. Last year, the warming Pacific was going to cause the entire Eastern Seaboard to be immolated by hurricanes. This year, it's the opposite. Do these guys get paid bonuses for hyperbole?

Didnt they say lst year that it was going to be a horrible Hurrican season? I could have sworn they did.

If you want to know the weather look out the window.

What we really need is some kind of rodent to come out and tell us what the hurricane season will be.

Winter has the Groundhog.

How about a muskrat named Chocolate City Slim.

They did say last year was to be very bad. Started with something like a prediction of 12 named storms and 9 hurricanes. Kept bringing the numbers down the rest of the year. So, I guess they guessed wrong.

There's this strange perception that some sort of recordbreaking season was forecast last year because of global warming.

Which is completely fictional, of course.

An above-average season in terms of total activity was forecast - a slightly below average season happened, because of an unforecast El Nino (which can be very difficult to forecast itself, and you have to forecast the state of ENSO to forecast the Atlantic Hurricane season.)

And very few storms hit the US. Nobody really hyped a specific US landfall threat other than the incompetent buffoons at AccuWeather.

Max Mayfield's report on expected hurricane activity for 2006. Yes Doctor Mayfield said that warming Pacific flows would be a major contributor to the Atlantic hurricane season.

Oh yes they did. The Guardian, June 1st, 2006:

17 Storms Slated For 2006 Hurricane Season.

Ill wind blows over storm-hit lands

The US hurricane season starts today with predictions of severe turbulence ahead

Alberto, Beryl, Chris and Debby. Somewhere over the Atlantic, a combination of warm sea surface temperatures and wind shear is brewing up a string of tropical storms that threaten to unleash a fresh season of devastation on coastal America.

With New Orleans still surrounded by the wreckage of Katrina, a new hurricane season gets under way today - and with it, the realisation that the coming six months could well bring a repetition of the panic and confusion that revealed a vulnerability many Americans had previously been unaware of.

Yesterday, a new forecast from the respected team of hurricane experts at Colorado State University predicted 17 named storms in 2006, including nine hurricanes. Five of those will be category three storms, with winds of more than 110 miles per hour. "We believe 2006 will be a very active season in the Atlantic basin," the report said.

In 2006

The University of Colorado team predicts that this year there will be 17 named tropical storms, of which 9 will be hurricanes. Of these, five will be serious Category Three storms.

A Category Three hurricane features winds of more than 110mph.

Researchers believe the chance of a major storm like this making landfall in the US next year is 82%.

It is most likely to strike the east coast, including Florida.

Repeat of the story from the Guardian mentioned earlier:

Researchers believe the chance of a major storm like this making landfall in the US next year [2006] is 82%.

It is most likely to strike the east coast, including Florida.

The bold face type is in the original.

Actually they do. Their pay is based on ratings. Which statement is likely to get more viewers: "Weather is going to be same old same" or "Disaster, we're all going to die!"

In the words of Rushbo, "Follow the money".

State and local governments along the Atlantic and Gulf coasts are heeding the alarm of last year's record onslaught and forecasts of another worse-than-normal hurricane season this year. (USA Today, 6/1/06)

The 2006 Atlantic hurricane season will be very active with up to 10 hurricanes...it appears that the Pacific Ocean water conditions known as El Nino and La Nina will not have any impact on the Atlantic hurricane season this year, forecasters said. (MSNBC, 5/22/06)

We flooded in Brownsville today. It was so weird. My son called me to take him to lunch because it was " raining" It was sprinkling. About 10 minutes later we were at Star and it was pouring and lightening flashing everywhere. It seemed to let up some so I took him back to work and headed to my office. I hit major flooding that was coming up on the hood and transformers were popping. There was no place to pull over but I made it thru . Many didn't though. All this happened in less than 30 minutes.

My daughter lives about 45 minutes from there, she is a Drug - Rep and covers Brownsville.

We, more in the central coast area, had a terrific storm in the middle of the night and got 1 1/2 inches of rain. I thought it was coming from the south but perhaps it moved down your way!
