Now in its third year, the current drought has many Georgians
wondering if the state will ever return
to normal weather. But state climatologist David Stooksbury says
the drought is part of a historically more normal climate
pattern.
Stooksbury, who is also a professor of engineering in the
University
of Georgia College of Agricultural and Environmental Sciences,
doesn’t see drought as strange or even unusual. But that doesn’t
mean the state will be a desert anytime soon.
“The state has now returned to a more normal climate
pattern,
with greater year-to-year variability,” Stooksbury said.
Drought is part of the overall history of the Southeast, he
said.
The history also contains long periods of wetter weather.
“We will have more years that are extremely wet and more
years that are extremely dry, which is historically the more
common pattern,” he said.
Unusually Mild Weather
Farmers and others looking back now recall extended times of
wet,
mild weather in the 1960s and ’70s. That weather makes the
current
drought seem that much more unusual. But those days weren’t the
“normal” that people think they were.
“If you look back at droughts, the ’60s and ’70s were the
abnormal years,” Stooksbury said. “They had very little
variation.”
In the ’60s, central Georgia had only one month of drought. And
throughout the ’70s, the same area had only 13 months of
moderate,
extreme or severe drought.
Drought Still Grips State
Though rains brought relief to parts of the parched state in
September,
Georgia remains under drought conditions. As of Oct. 27, the
soil
moisture in 80 percent of the state was short to very short.
State water restrictions remain in effect.
The severity of the drought varies from region to region,
Stooksbury
said. Georgia is the largest state east of the Mississippi
River,
and the state has a diverse landscape. This allows for
variations
in the drought’s severity. The state’s northwestern corner is
in mild drought, the west central area in severe drought and the
south central part near normal for this time of year.
A drought doesn’t start during summer. It’s what happens the
winter before that marks the severity of a drought.
“Wetter” Winter Expected
Winter rains usually replenish the state’s soil moisture and the
groundwater supplies lost during the year. However, the past two
winters haven’t brought the needed rain.
With the dissipation of the Nino family — for now — Stooksbury
said the state will probably return to near-normal rainfall this
winter.
“The global ocean temperature pattern is close to neutral,
which means we don’t have the more robust, forcing pattern for
the weather,” he said. The state is less likely to have the
wet winter of El Nino, but it’s also less likely to have the dry
winter of La Nina.
“We don’t have a well-defined guide for this winter,”
Stooksbury said. “But we’ll tend toward a more normal
winter.”
He said another El Nino event is possible for the 2001-2002
winter.
It would still take several months of above normal rainfall to
pull out of the drought, he said. Even normal rainfall through
winter will not solve the problem.
Going into the next growing season, Stooksbury believes the
state
will have adequate soil moisture to germinate seeds. But
groundwater
and deep-soil moisture levels will remain low.
“We should have enough moisture in the top soils to get the
crops up,” Stooksbury said. “But there won’t be much
of a cushion for next year.”
