Top U.S. weather story of 2007: the Southeast U.S. drought

The year 2007 is in the record books as the driest or second driest year on record for much of the Southeastern U.S. A mere 31.85 inches of rain fell in Atlanta, Georgia, during the year, 62% of the average of 48 inches. This year's rainfall total just missed breaking the record of 31.80 inches set in 1954. Rainfall records in Atlanta go back to 1930. The drought was worse in Alabama, where Birmingham had its driest year on record--just 28.86", a full 25 inches below average, smashing the record low of 36.14" set in 1931. Huntsville was even drier--a mere 28.65"--29 inches below average. Surrounding areas of Tennessee, North Carolina, South Carolina, Kentucky and Virginia also experienced extraordinarily dry years (Figure 1).


Figure 1. Drought conditions in the Southeastern U.S. were at the highest level possible--exceptional drought--at the end of 2007. Image credit: NOAA.

Although the current drought is exceptional, Atlanta has had much drier 2-year periods. During the drought of 1954-1955, Atlanta received 68.23 inches of precipitation--a 28 inch deficit from the normal 2-year rainfall. The deficit for the past two years is only 16 inches, since an average amount of rain fell in 2006 (48.46 inches). Based on the climatological record, Georgia can expect a two-year drought about once in 25 years, and a drought lasting three or more years about once every 40 years. Drought is part of the natural cycle in Georgia, and it would not be a surprise to see the drought of 2007 continue until the winter of 2008. Although December 2007 saw Atlanta's first above average month of rainfall since November 2006, the coming two weeks look very dry, and the current La Nina atmospheric pattern usually brings below average rainfall.

What is causing the Georgia drought?
Two main factors are responsible for the Southeast U.S. drought. Most importantly, a persistent jet stream pattern has set up that steers storms away from the region, and into Texas instead. Texas, which suffered extreme drought in 2006, found itself awash in floods in 2007, as the jet stream pattern brought storm after storm to the state. Another contributing factor to the current Southeast drought is the absence of tropical storms and hurricanes during 2006 and 2007. These storms are an important part of the annual rainfall budget for the Southeast. For example, in 2005, 29% of Atlanta's yearly rainfall came from five tropical storms:

1.36" Arlene June 11-12, 2005
1.40" Katrina, August 29-30, 2005
5.48" Cindy, July 6-8, 2005
5.41" Dennis, July 9-12, 2005
2.94" Tammy, October 6-8, 2005


Figure 2. Over ten inches of rain fell on Atlanta in 2005 from two tropical cyclones, Dennis and Cindy. Tropical cyclones accounted for 29% of Atlanta's rainfall that year. Image credit: NOAA/HPC.

There is little evidence that global warming contributed to this drought. The Southeastern U.S. has cooled by about 0.1° F over the past 100 years, even as the rest of the globe has warmed 1° F. The reasons for this lack of warming in the Southeast are not fully understood. One theory is that the cooling is due to air pollution blocking sunlight. Another theory, proposed by Georgia State Climatologist David Stooksbury, attributes the cooling to the shift from 80 percent row crops (like corn and cotton) to 60 percent forest. Land use changes like this can have a significant impact on how solar energy heats the air once it is absorbed by the soil.

Why Atlanta is vulnerable to drought
Atlanta, unlike most major cities, grew up around rail lines rather than a major body of water. Although the Chattahoochee River runs through Atlanta, the city lies on top of a watershed, with no large bodies of water upstream. The rivers and streams in the region are small, and the bedrock limits how much ground water is available. The Lake Lanier reservoir that supplies Atlanta with most of its water was constructed in the 1950s. Since that time, the population of Atlanta has quadrupled, increasing the pressure on the reservoir's limited water. Lake Lanier is at its record lowest level--more than 19 feet below average. If the drought continues into the summer of 2008, and no tropical storms arrive to break the drought, Atlanta may run out of water.

By 2030, the population of the Atlanta metropolitan area is expected to increase from 5 million to 9 million. Current water resources in the regions will be unable to support this population increase, unless planners make a concerted and expensive effort to plan ahead. The expected increase in temperatures over the coming decades due to global warming will make future droughts in the region even more severe, so Atlanta has a very tough road ahead of it.

Georgia Drought Series 2 (HurricaneIan)
Like my last series, this Series of photos concern the drought in North Georgia. These were taken at Lake Chatuge, Georgia. This is near the North Carolina Line and near a town called Hiawassee. North Georgia is experiencing a major drought. These docks are designed to float and adjust to water depth, however, now they are high and dry. The depth of these lakes varies from season to season, however, this is by far the lowest I have ever seen it. This water is not only used for drinking, this is also the primary supply of hydro-electric power for the region. The drought is causing other problems as well, the leaves are not changing properly, some look burnt and others fall off before turning. North Georgia and surrounding areas need rain in the worst way. The good news is it is raining

Here are a few scenes from Lake Lanier in Buford, GA. We are going through a record setting drought this year. Everyday now we set a new record for the Lake level since the inception of the lake in the 1950's

Just checking in again; I had to step out for a while.

Low tonight in Nassau is supposed to be 58, with the wind chill making it feel like 48. In the extreme NW Bahamas it's supposed to drop to 48, with a similar wind chill. Our record low here (Nassau) is the mid-40s, if I remember correctly (I need to research this lol).

I don't know if we're going to have any records broken in Freeport or Abaco tonight. It's possible, I suppose.

33F in Baytown. Lows expected in upper 20's tonight. Mild compared to elsewhere, but still too cold for me.

I am surprised about how cold it will be in Northern Florida tonight.

At 0:00 AM UTC, Tropical Low [995 hPa] located near 14.1S 128.6E or 160 kms north-northeast of Wyndham and 310 southwest of Darwin had 10 minute sustained winds of 25 knots with gusts up to 35 knots. The low is reported moving west-southwest at 5 knots.

There is the possibility that the low will develop into a TROPICAL CYCLONE in the Joseph Bonaparte Gulf tonight, and GALES could affect coastal and island communities between Mitchell Plateau in Western Australia and Daly River Mouth in the Northern Territory early tomorrow.

Tropical Cyclone Watches/Warning
===============================

A Cyclone WARNING has been declared for coastal and island communities from Mitchell Plateau in Western Australia to Daly River Mouth in the Northern Territory.

A Cyclone WATCH has also been declared for coastal and island communities from Daly River Mouth to Goulburn Island, including Darwin and the Tiwi Islands.

BTW, for all the up north jokesters who are finding funny flustered Floridians, just keep in mind that most homes in south Florida have no heating and little cold-weather insulation. Therefore, if it's 30 degrees outside, it may be only 35 degrees INSIDE. Even in coastal GA or AL I'm sure this is not the case.

It's never been freezing anywhere in the Bahamas. The coldest readings ever have actually taken place on Andros, which is large enough for radiational effects to come in play when it is calmer. 34 has happened there, but freeport has never fallen below 41. The cold winds off fl have to cross the deep warm waters of the gulf stream for several hours, so advective cold waves are modified some.


I don't have access to local records, so I can't confirm or deny that. I'm pretty sure there will be some discussion of record low temps during the weather forecast tonight, however [lol].

ON the topic of freezing in Grand Bahama, Freeport residents swear that they had snow on a winter night in 1978 (or was it Jan 79? whenever South Florida had that really cold snap), but I believe the meteorologists only allow that it may have been hail or freezing ice, both of which have been observed in the Bahamas on more than one occasion. Walker's Cay, which is about as far north as you can get and still be in the Bahamas, is not likely to have seen snow either, again due to the warming effects of the Gulf Stream waters which pass very close by.

I cannot wait for it to come....the only cold I ever experience is from my refrigerator when i open it.

I have to admit though....nights can be chilly when radiation cooling is max.

My forecast calls for the cold air to reach me in the Leeward Islands. That must be some airmass if it is expected to reach me.
