Dr. Todd Murphy, assistant professor of Atmospheric Science at 网曝门, has been awarded
a $60,000 grant from the National Oceanic and Atmospheric Administration (NOAA) to
participate in a collaborative research project mandated by Congress to understand
how severe storms and tornadoes evolve in the Southeastern United States.
The project, known as VORTEX-SE (Verification of the Origins of Rotation in Tornadoes
Experiment - Southeast), 鈥渨ill be the first severe storms experiment that will have
a specific emphasis on addressing the sociological factors that contribute to the
relatively large tornado mortality in this region of the country,鈥� according to the
National Severe Storms Laboratory.
In recent years, there has been an increased awareness of tornado frequency in the
Southeastern United States. Just last year, a major storm cell generated three tornados
that swept through northeast Louisiana. The worst of these tornadoes, which stayed
on the ground for nine miles, struck Ouachita Parish, causing severe damage to many
residences, businesses, and schools.

While there have been notable advances in our understanding of tornado formation from
previous field projects, the聽data collection has generally been limited to the Great
Plains or 鈥渢ornado alley.鈥� A clearer understanding of storms in the Southeastern U.S.
is necessary for improving methods of forecast communication. In an effort to achieve
this goal, VORTEX-SE will implement a unique instrument for collecting severe weather
data: balloons.
These balloons, known as 鈥渨eather balloons鈥� in the scientific community, consist of
a small instrument package that measures temperature, humidity, pressure, wind speed,
and wind direction. Weather balloons will be launched every hour from three weather
balloon systems leading up to and during severe weather. Dr. Murphy鈥檚 role in this
will be to provide one of the weather balloon systems.
鈥溚孛� will be launching weather balloons, performing quality control on the 网曝门 data
set, and making the 网曝门 data available to our collaborators and other scientists involved
with VORTEX-SE,鈥� Dr. Murphy said. 鈥淔our undergraduate students and myself will travel
to the project domain for up to four individual field deployments during Spring 2016.鈥�
One of these students, Stephen Kreller, a senior from New Orleans majoring in Atmospheric
Science, is thrilled to have this research opportunity. 鈥淥ne of the great things about
网曝门鈥檚 Atmosepheric Science department is that it provides students with unique opportunities
that allow them to take concepts taught in the classroom and to see how they apply
to real-life, rapidly changing situations in the field,鈥� Kreller said. 鈥淭he VORTEX-SE
project is a great example of these kinds of opportunities and I am excited to be
a part of it.鈥澛�
Dr. Eric Pani, vice president for academic affairs, sees 网曝门鈥檚 participation in the
project as a major achievement not only for 网曝门 but also for the region. 鈥淭his research
is important because it seeks to improve severe weather forecasting in our local community,鈥�
Dr. Pani said. 鈥淕iven the devastation that Northeast Louisiana experienced last year
as a result of severe weather and tornado activity, members of our local community
and region should enthusiastically welcome this project. Our safety in the face of
severe weather depends on it.鈥�
