Until about 15 years ago, weather technology was of World War II
vintage. Now more powerful radar can detect not just precipitation
but wind speed and circulation, and from twice as far away.
Powerful computers can calculate variables and give forecasts that
are twice as accurate.
A five-day forecast today is about as reliable as a two-day
forecast was in 1980. Weather can be predicted for very specific
areas, and for very specific events, giving people the ability to
plan their lives in great detail as it relates to the
weather.
"I'd say if our depth of knowledge used to be 10 feet deep, now
it's 100,000 feet deep," said Dan McCarthy, a meteorologist with
the National Weather Service's Storm Prediction Center in Norman,
Okla.
The growth of the Weather Channel is also a reflection of our
preoccupation. The network was launched in 1982 with much
skepticism as one of cable television's first channels.
"We heard it all the time: 'Weather? Twenty-four hours a day? Who's
going to watch that?'" said Ray Ban, a meteorologist with the
Weather Channel since its inception. "The sophistication of our
programming was modest and I'm being generous. The difference
(between now and then) is black and white."
More than ever, weather is also literally money. Weather events
shape stock prices and corporate profits, making it all the more
newsworthy. Giant financial institutions like Merrill Lynch have
their own meteorologists. Paul Janish works in Houston for Merrill
Lynch's global commodities unit, preparing weather data that
becomes part of the company's business strategies and
decisions.
"Weather has gotten a lot more integrated into the overall business
environment," said Janish, who used to work for the National
Weather Service. "Companies are looking into ways to leverage
weather, to better manage their resources. With energy supplies so
constrained, the weather is going to become a more integral part of
the business world."
In the business world, ice cream manufacturers and beverage
companies wish for hot summers. Municipal budgets are made or
busted on the number of snowstorms. Dry winters that produce little
runoff in the summer can hurt companies that operate hydroelectric
plants. The past hurricane season affected about 80 percent of the
offshore gas infrastructure in the Gulf of Mexico.
All these events amount to billions of dollars and can be
anticipated, in some part, by meteorologists, and dealt with using
financial instruments like hedge funds, insurance policies, and
energy futures.
For that reason, the demand for information about the weather will
only grow _ as will our fear and loathing.
One of the next advancements in weather technology, McCarthy said,
is a new form of radar called phased array radar. Current Doppler
radar scans a storm every five to six minutes. Phased array radar
can scan a storm every minute, giving forecasters a sort of
live-time view of a storm. This kind of technology translates,
among other things, into potentially being able to double the
warning time of an approaching tornado.
It could save lives, and will certainly make for great
television.
"It's the awe of the weather," Ban said. "It impacts most of what
we do It's an awesome event that we try to predict but it's always
bigger than we are. It creates inspiration and fascination. And
there's a gravitation towards the awe of it all."
Even if sometimes the weather is more bluster than disaster.
In September, 1997, a Pacific hurricane, Nora, made its pass
through Tucson, Ariz., in what, at first, promised to be a rare and
dramatic event in the desert city but turned out to be a dud. A
meteorologist from a local television station and his camera crew
set up for a live shot on the third-floor balcony of the National
Weather Service building in Tucson. He stood atop a garbage can and
leaned away from the building so the wind would toss his
hair.
All of this was witnessed by several amused weather service
employees.
Their reaction was a mix of eye-rolling and empathy. Empathy
because the weather experts all played some part in blowing the
call. Eye- rolling because reporting the weather had come to this:
standing on garbage cans as a way of attempting to stage and direct
the weather as if it were some kind of disaster film.
"My first reaction was 'good grief,'" said another meteorologist
who witnessed the live shot. He did not want his name used lest he
be viewed as poking fun of a colleague. "But at the same time, I
was glad I wasn't the one who had to get in front of the camera and
talk about this hurricane we all predicted would be a big
storm."
