Depending on whom you believe, we
are going to have a busy hurricane season or a not so
busy one.
Depending on whom you believe, our ability to predict
hurricanes is severely hampered, or everything is fine.
Such is the situation with Hurricane Season 2007, which
officially opened June 1 and continues through November.
Subtropical Storm Andrea, though, never got the memo.
Andrea formed a couple hundred miles off the coast of
Savannah, Ga., on May 9. The storm produced gale-force
winds that blew forest fire smoke from the northern
parts of Florida into Miami’s skies and 10 foot waves
that managed to drown a surfer in Volusia County. Andrea
was the first pre-season named storm to form since
Tropical Storm Ana in 2003. Andrea was also the first
pre-season storm in the Atlantic since Tropical Storm
Arlene in 1981. (For some context, consider: Arlene
formed three months before the launch of MTV, a network
that repeatedly showed the Buggles’ video, “Video Killed
the Radio Star.”)
And so, on May 22, the National Oceanic and Atmospheric
Administration announced that, according to forecasters’
calculations, there is a 75 percent chance the “Atlantic
Hurricane Season will be above normal this year.” By
above normal, NOAA meant “13 to 17 named storms with
seven to 10 becoming hurricanes, of which three to five
could become major hurricanes of Category 3 strength or
higher,” said NOAA’s head administrator, Retired Admiral
Conrad C. Lautenbacher. As if to underscore the pending
doom, Tropical Storm Barry formed on June 1, the first
day of hurricane season. It crashed into Tampa, bringing
much rain and not much else.
Two years ago was the most active hurricane season in
recorded history, spawning so many named storms, 28 in
all, that hurricane forecasters began naming cyclones
after Greek letters. Of those storms, 15 were hurricanes
and seven were deemed “major hurricanes,” including
Hurricane Katrina, which devastated New Orleans, and
Hurricane Wilma, which caused significant damage in
South Florida.
An above-average season was also predicted for 2006: 17
named storms, nine of them hurricanes and five of them
powerful hurricanes. But that season only produced 10
named storms, with five of them being hurricanes and
just two of those major ones. NOAA blamed the
discrepancy on El Niño, which “rapidly developed and
created a hostile environment for Atlantic storms to
form and strengthen. When storms did develop, steering
currents kept most of them over the open water and away
from land,” according to NOAA’s May 22 statement.
This season, La Niña may pay a visit, which would
produce “warmer-than-normal sea surface temperatures in
the Atlantic Ocean.” Emphasis on the word “may.”
“There is some uncertainty this year as to whether or
not La Niña will form, and if it does how strong it will
be,” Gerry Bell, lead hurricane forecaster at NOAA’s
Climate Prediction Center, said via NOAA. But even if La
Niña doesn’t show up, “the conditions associated with
the ongoing active hurricane era still favor an
above-normal season,” Bell stated.
Don’t tell that to the British. According to the United
Kingdom’s Met Office, there will only be 10 named storms
in 2007, in addition to the two that have already come
and died, the Palm Beach Post reported on June
21. The reason: a cooling trend on the Atlantic’s
surface. The UK Met uses a “dynamical” global climate
computer model system instead of NOAA’s “statistical”
system. “Our method… uses models of the climate that
include all the laws of physics and supercomputers
together to predict what’s going to be happening over
the coming season,” UK Met’s Matt Huddleston told the
Palm Beach Post.
Meanwhile, because of rising costs, the U.S. Department
of Defense has decided to launch only four new weather
forecasting satellites instead of the intended six that
will replace orbiting climate devices that are expected
to conch out soon, the Associated Press reported on June
4. Those new satellites will also be “less capable” than
their predecessors. As a result, the United States will
“rely on European satellites for most of the climate
data.” “Unfortunately, the recent loss of climate
sensors… places the overall climate program in serious
jeopardy,” a Dec. 11 report from NOAA and NASA, obtained
by the AP, stated. The American Association for the
Advancement of Science issued an equally severe
statement last May: “Declines will result in major gaps
in the continuity and quality of the data gathered about
the Earth from space.” And Bill Proenza, the director of
NOAA’s National Hurricane Center, warns that one
particular satellite, QuickSTAT, will reach the end of
its estimated life soon. He also questioned, in the
pages of the Miami Herald, NOAA’s priorities,
most specifically a $700,000 budget cut for hurricane
predictions and a $4 million campaign to celebrate a
purported 200-year anniversary of NOAA.
In response, Proenza was issued a letter that basically
told him to stop talking to the media. NOAA also issued
a press release assuring that the agency’s weather
satellites currently work and are ready. “With an active
Atlantic hurricane season expected for 2007, NOAA’s
high-powered satellites are ready to send forecasters a
steady stream of crisp detailed images, and other
important data, of any storm that develops in the
Western Hemisphere.”
The release goes on to state NOAA has a “fleet” of “four
geostationary spacecraft: two are in operation, one is
stored in orbit as a ready backup and one satellite
currently used to provide better coverage of South
America as part of the World Meteorological
Organization’s World Weather Watch Global Observations
Systems. GOES are the nation’s primary hurricane
spotters from space.” NOAA also has polar-orbiting
satellites: “two that are operational, including a
spacecraft in a joint venture with Europe, with three
more serving as backup satellites.” The POES, as the
release calls them, are “key in monitoring changes in
the atmosphere and ocean temperatures and climate
phenomena, such as El Niño and La Niña.”
In short, “NOAA Satellites Show Moxie,” the release
states, and they were able to send 11,736 images of
cyclones during the busy 2005 season. The release also
stated, NOAA and NASA “are planning the next generation
of satellites that will strengthen the prediction and
tracking of hurricanes.”
“Since the first GOES satellite began monitoring the
weather in 1975, we have never stopped trying to make
this system better,” Mary Kicza, a NOAA assistant
administrator, said in the press release.
Besides, if things go awry, there’s always UK Met.
