The University of Tennessee in Knoxville has signed a memorandum of agreement with the Atmospheric Turbulence and Diffusion Division, or ATDD, of the National Oceanic and Atmospheric Administration’s Air Resources Laboratory to advance collaborative research in atmospheric sciences. ATDD has headquarters in Oak Ridge.

The agreement was signed Wednesday, February 15, at ATDD headquarters in Oak Ridge, and it will help with joint efforts to advance understanding of air pollution, atmospheric transport processes, and weather on a regional and national level, a press release said. It also will create educational opportunities for undergraduate and graduate students to collect scientific data, develop models and simulations, and transition research to applications and commercial use.

“The mission of the collaboration will be to train the next generation of scientists and engineers and provide the best available atmospheric data and scientific analysis to the global scientific community, to local and national decision makers, and to the general public,” said Bruce Baker, director of the ATDD.

Climate and energy scientists at Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise.

“For the first time, we were able to apply data at a high enough resolution to be relevant,” said ORNL’s Melissa Allen, co-author of “Impacts of Climate Change on Sub-regional Electricity Demand and Distribution in the Southern United States,” published in Nature Energy.

Allen and her team developed new algorithms that combine ORNL’s unique infrastructure and population datasets with high-resolution climate simulations run on the lab’s Titan supercomputer. The integrated approach identifies substations at the neighborhood level and determines their ability to handle additional demand based on predicted changes in climate and population.

The new, high-resolution capability can explore the interconnections in complex systems such as critical infrastructure and weather and determine potential pathways to adapt to future global change, a press release said. [Read more…]

UT study predicts extreme climate in eastern United States

From extreme drought to super storms, many wonder what the future holds for the climate of the eastern United States. A study conducted by researchers at the University of Tennessee in Knoxville does away with the guessing.

Results show the region will be hotter and wetter.

Joshua Fu, a civil and environmental engineering professor, and Yang Gao, a graduate research assistant, developed precise scales of cities that act as a climate crystal ball, seeing high-resolution climate changes almost 50 years into the future.

The study found that heat waves will become more severe in most regions of the eastern United States and that both the Northeast and Southeast will see a drastic increase in precipitation.
