A record amount of rain has fallen in the Tennessee River Valley in 2018, and the year isn’t over yet. The rain might not be either.

The previous record of 65.1 inches of rain was set in 1973. The record, based on 129 years of weather data, was announced by the Tennessee Valley Authority on Friday.

“As 2018 draws to a close, yearly rainfall totals for the TVA region continue to climb to near record levels, and the trend for above average rainfall totals continues right up to year’s end,” the public utility said.

“For the week before Christmas, rainfall averaged two inches in the eastern Valley and 1.4 inches in the western Valley,” said James Everett, senior manager for TVA’s River Forecast Center. “We began spilling and sluicing at several locations the day after Christmas to increase flows and increase flood storage capacity, and that will likely continue into the New Year.” [Read more…]

For the U.S. military, accurate weather prediction is vital to both the planning and execution of worldwide missions. To extend its weather modeling capabilities, the U.S. Air Force has joined the computing experts at the U.S. Department of Energy’s Oak Ridge National Laboratory in a strategic collaboration that includes procurement and operation of a new high-performance weather modeling computer system. Key members of the Air Force and ORNL teams, including computing and global security team members, gathered on July 10 to kick off this project and tour the facilities supporting the new system, according to a story posted by ORNL.

The Air Force 557th Weather Wing provides the Air Force and Army with global- and regional-level numerical weather model forecasts. With the increasing scale of the requirements for the new system, the Air Force and ORNL identified an opportunity to take advantage of the capabilities of ORNL’s National Center for Computational Sciences—including expertise in high-performance computing facilities and infrastructure, systems administration, computing procurement and acquisition, and system operations, the story said.

“We learned about the Air Force’s needs, and it was immediately clear that ORNL could help them solve their problems,” said Jim Rogers, NCCS director of computing and facilities. “We can integrate the Air Force weather team’s needs into our facilities in a cost-effective way, leveraging our capabilities to deliver exceedingly high availability to support their mission.” [Read more…]

Peter Thornton

Peter Thornton, deputy director of the Oak Ridge National Laboratory’s Climate Change Science Institute and group leader for the Terrestrial Systems Modeling Group in ORNL’s Environmental Sciences Division, will describe the current best understanding of climate change on Thursday, February 22 at 7 p.m., a press release said. The public is invited to attend this free program.

Thornton’s presentation will describe evidence regarding historical and modern climate changes, and projections of future climate based on Earth system models, the press release said. His current research involves the development, evaluation, and application of Earth system models for future climate change prediction. His areas of expertise include the interaction of water, energy, carbon, and nutrients within land ecosystems, the interactions of vegetation communities with the atmosphere, and weather observations over land, the release said. (See a brief ORNL summary here.)

The presentation, co-sponsored by Tennessee Citizens for Wilderness Planning, Climate Coalition Lobby-Knoxville, and the Citizens Climate Coalition at Oak Ridge Unitarian Universalist Church, will be in the Social Room at the Oak Ridge Civic Center.
