'Hurricane Hunters' Weather Storms to Save Lives

WASHINGTON, Jan. 17, 2013 - As the nation rebounds from 19 named storms and 11 major hurricanes in 2012, a small but hardy military organization keeps relentless watch to track and prepare for such disasters.

Located at Keesler Air Force Base, Miss., the 53rd Weather Reconnaissance Squadron, dubbed the "Hurricane Hunters" of the Air Force Reserve, is the Defense Department's sole organization dedicated to flying into tropical storms and hurricanes. The unit has performed the mission since 1944.

In a "DOD Live" bloggers roundtable today, Lt. Col. Jon Talbot, 53rd WRS chief meteorologist, and Capt. John Brady, a meteorologist with the squadron, said collecting winter storm, hurricane and tropical cyclone data for the National Weather Service is critical in mitigating loss of life and property.

Typically, a winter storm mission begins only if the weather system will have a large, societal impact somewhere in the United States, Talbot explained.

"Winter storms kill more people than hurricanes do," Talbot said, noting his team's specialty in analyzing data over water, where information is sparse. "If the National Weather Service is seeing a lot of uncertainty in their [data], they'll contact our liaison team."

Talbot and Brady oversee 20 flight meteorologists responsible for acting as mission directors aboard the fleet of 10 WC-130J reconnaissance aircraft and crews from the 403rd Wing, also based at Keesler. The weather experts collect and relay information such as storm center and intensity, known as models or numerical predictions, to the Miami-based National Hurricane Center.

"Over the open waters of the Pacific and Atlantic, there's nothing out there for the models to ingest, so we get extra data to pump into the model," Brady said. "The forecast accuracy can go up 15 to 20 percent just by gathering that data."

But winter-storm tracking missions in the Northeast and Northwest corners of the United States, Talbot said, differ from conventional hurricane tracking. These are high-altitude missions, usually at 30,000 to 34,000 feet, that supplement data from an upper-air balloon

"It's not an active environment [as with] a hurricane, where you're right in the middle of it [because] you're a lot lower," Talbot said.

Brady agreed and explained the squadron's use of dropsondes -- small, expendable, parachute-like meteorological devices that collect information and send the coded data back to weather trackers.

"Our goal is to fly as high as possible and drop our weather dropsondes at predetermined points to measure the atmosphere ... and get that information to the National Weather Service so they can increase the forecast accuracy for developing winter storms," Brady said. "The longer they flew, the lighter the aircraft got due to less fuel, so they were able to get higher and higher with each one." Hurricane Hunters, particularly in the Atlantic basin, often fly a day or so ahead of a weather system before its main impact, he added.

The data can even provide rescuers an immediate, life-saving advantage, Brady said, relating a recent example of collaboration with the Coast Guard. In October 2012, Tropical Storm-turned-Hurricane Rafael caused heavy rains and formidable gusts that thwarted rescue efforts for two men and one woman whose twin-engine Piper Aztec aircraft crashed near St. Thomas in the U.S. Virgin Islands.

Coast Guard rescue crews called on the Hurricane Hunters, who were in the area and were able to spot from high above an oil slick and aircraft debris. Although the other two passengers perished, the woman was rescued, thanks to the Hurricane Hunters' ability to identify and relay critical coordinates of the survivor's location.

"[The Coast Guard] took over and ultimately did find the rest of the debris and one female survivor still clinging to life," Brady said. "I'm sure she was extremely grateful to see some folks coming to get her, [and] that's just one example of how we can intercoordinate with the different branches through search and rescue."

After Hurricane Katrina crippled the Gulf Coast in 2005, Talbot said, the use of instruments such as remote wind sensors now enable the team to provide even greater detail about how winds are likely to affect a coastal area when a hurricane comes ashore.

"We're able to map the entire area under a hurricane," Talbot said. "During Katrina, we had only one or two airplanes [with that] instrument installed, and now we've gone to the entire fleet."

Talbot added that being able to map the area under a hurricane is a "gigantic benefit" for not only forecasters at the hurricane center, but for the local emergency management workers assessing how and where to evacuate people. The colonel also noted that collaboration with the National Hurricane Center and National Weather Service likely will pave the way to develop future capabilities such as enhancing radar and satellite communications to better track real-time hurricane changes.

"NASA has flown over hurricanes using ... high-altitude Global Hawks outfitted with special instrumentation," Talbot said. "We're trying to get to a point where we can develop [similar] remote sensors."

Still, mission requirements, Talbot noted, ultimately will be defined by the needs of the Hurricane Hunters' main customer, the National Weather Service's National Hurricane Center.

"[What we do at] the 53rd [WRS] and the Air Force Reserve has always been a great mission for us," Talbot said. "We're proud to be able to help mitigate the cost and protection of lives during hurricanes and we look forward to continuing this mission proudly."

'Hurricane Hunters' Track Isaac as Southcom, Northcom Prepare

WASHINGTON, Aug. 23, 2012 - With Tropical Storm Isaac bearing down on the Dominican Republic and Haiti and threatening to strengthen over the eastern Caribbean, the "Hurricane Hunters" from the Air Force Reserve's 53rd Weather Reconnaissance Squadron are in the air, relaying critical data to National Weather Service forecasters in Miami.

Meanwhile, staffs at both the U.S. Southern and Northern Commands are monitoring the storm closely and ensuring they are ready to provide support to civilian authorities, including the U.S. Agency for International Development and Federal Emergency Management Agency.

Three six-person crews from the 53rd WRS and their maintainers and support staff deployed to St. Croix from Keesler Air Force Base, Miss., last weekend, Air Force Lt. Col. Jon Talbot, the squadron's chief meteorologist, told American Forces Press Service. Operating out of the international airport there, they began flying their specially equipped C-130J Hercules aircraft through the storm Aug. 21.

On a typical mission that can run up to 12 hours, the aircrews crisscross the storm in what the teams call an "alpha pattern," he explained. Sophisticated onboard instruments and small canisters dropped by parachute to the ocean's surface collect accurate measurements of the storm's location and intensity.

That information is fed continuously to the National Hurricane Center via an onboard satellite link. In addition, the aircraft sends automated messages every 10 minutes, relaying barometric pressure, wind speed and direction, and other measurements.

"The reason this data is critical is because, with satellites, you can track where storms are and get a general picture, but you can't peer into the storm and physically measure what is happening at the ocean's surface," Talbot said. "That is the important piece of information you need to know when it comes to providing warnings to the public. The emergency management community needs to know what is going on near the surface of the ocean, because those are the winds that are going to come ashore."

With about six missions already under their belts during the past three days, Talbot said, the pace will pick up considerably as Isaac moves west toward the United States. "Currently, we are doing about three missions a day, but that will go up to four or five when the storm comes within 300 miles of the U.S. coastline," he said.

The Hurricane Hunters expect to move west along with the storm, redeploying to Keesler Air Force Base to resume those missions beginning this weekend. In the event that the crews have to evacuate Keesler, Talbot said, they already have alternate operating sites lined up. "We track these things pretty closely, because if we end up having to jump from here, we still have to continue flying and providing that data while we are evacuating our own resources," he said. "It becomes a big, tangled web, but it always works out pretty well."

As a precaution, aircraft and ships are being moved out of the storm's possible path and other assets are being secured, according to Southcom spokesman Army Lt. Col. Darryl Wright. Planning teams are busy running rehearsal meetings and preparing to verify personnel and resource requests, if USAID issues them, he said.

Wright emphasized that military support, if provided, would be part of a coordinated U.S. response led by civilian authorities. "We conduct close coordination and planning and provide DOD support to relief efforts upon request," he said. "Through this close coordination, we ensure that we respond with the most efficient means available to the U.S. government."

In terms of disaster response, Wright said efficiency is typically more important than speed in reducing suffering and saving lives.

Northcom, too, is in a monitoring mode. But with the storm expected to intensify late this weekend when it hits the Atlantic and the Florida Straits, the command deployed a defense coordinating officer and element to Puerto Rico on Aug. 20 to support FEMA, John Cornelio, Northcom's media operations chief, told American Forces Press Service.

The element of about 20 people is assessing the situation and standing ready to provide assistance, if requested. "We have learned the value of being forward enough to cut down on the response time, if required," Cornelio said.

With Isaac's path still anyone's guess, officials say it's too soon to know whether it will hit Tampa, site of next week's Republican National Convention. Northcom has a team deployed there to support the Secret Service during the convention, Cornelio reported.
