Pulling Clouds into Focus: Frontier Simulations Bring Long-range Climate Forecasts within Reach - Technology Org

The world’s first exascale supercomputer will help scientists peer into the future of global climate change and open a window into weather patterns that could affect the world a generation from now.

The research team used Frontier, the 1.14-exaflop HPE Cray EX supercomputer at the Department of Energy’s Oak Ridge National Laboratory, to achieve record speeds in modeling worldwide cloud formations in 3D. The computational power of Frontier, the fastest computer in the world, shrinks the work of years into days to bring detailed estimates of the long-range consequences of climate change and extreme weather within reach.

“This is the new gold standard for climate modeling,” said Mark Taylor, a distinguished scientist at Sandia National Laboratories and lead author of the study. “Frontier’s unique computing architecture makes possible things we couldn’t do before.”

The study earned the team a finalist nomination for the Association of Computing Machinery Gordon Bell Special Prize for Climate Modeling. The prize will be presented at this year’s International Conference for High Performance Computing, Networking, Storage and Analysis, or SC23, in Denver where the team will present their results on Nov. 15.

Gauging the likely impact of a warming climate on global and regional water cycles poses one of the top challenges in climate change prediction. Scientists need climate models that span decades – at least 40 years – and include detailed atmospheric, oceanic and ice conditions to make useful predictions.

But 3D models that can resolve the complicated interactions between these elements, particularly the churning, convective motion behind cloud formation, have remained computationally expensive, leaving climate-length simulations outside the reach of even the largest, most powerful supercomputers — until now.

The Energy Exascale Earth System Model, or E3SM, project overcomes these obstacles by combining a new software approach with massive exascale throughput to enable climate simulations that run at unprecedented speed and scale. The Simple Cloud-Resolving E3SM Atmosphere Model, or SCREAM, focuses on cloud formations as part of the overall project.

“It’s long been a dream for the climate modeling community to run kilometer-scale models at sufficient speed to facilitate forecasts over a span of decades, and now that has become reality,” said Sarat Sreepathi, a co-author of the study and ORNL performance coordinator for the project. “These kinds of simulations were computationally demanding enough to warrant an exascale supercomputer. Without Frontier, it doesn’t happen.”

Peter Caldwell, a climate scientist at Lawrence Livermore National Laboratory, and his team spent the past five years building a new cloud model from scratch targeted to run on the graphics processing units, or GPUs, that power Frontier and other top supercomputers.

“Most climate and weather models are struggling to take advantage of GPUs,” Caldwell said. “SCREAM is of huge interest to other modeling centers as a successful example of how to make this transition.”

HPE, Frontier’s maker, assisted in the optimization effort through the Frontier Center of Excellence at the Oak Ridge Leadership Computing Facility, which houses Frontier.

“The performance-portable codebase of SCREAM gave us a great vantage point for early deployment on Frontier, and further optimizations enhanced our computational performance,” Sreepathi said. “The overall effort is a nice exemplar of interdisciplinary collaboration between climate and computer scientists.”

Adapting the code to run on GPUs brought immense gains in performance. SCREAM can run across 8,192 of Frontier’s nodes to simulate more than a year’s worth of global cloud formations – 1.25 years total – in a single 24-hour run, a feat beyond the reach of any previous machine.

“That means these long-range simulations of 30 or 40 years are now doable in a matter of weeks,” Sreepathi said. “This was practically infeasible before.”

The simulations at 3-kilometer resolution allow a level of detail that enables researchers to overlay the results on satellite images for comparison.

“The resemblance is striking,” Taylor said. “This kind of resolution and scale allows us to predict the impact of climate change on severe weather events, on freshwater supplies, on energy production.”

Sreepathi said he expects further success stories on Frontier and on the next generation of exascale supercomputers.

“We want to achieve even higher resolutions and to couple the atmospheric model with other earth system components such as oceanographic data for a holistic view,” he said. “Thanks to the work we’ve put in, SCREAM is portable across diverse computer architectures  – not just Frontier’s – so we’re well-positioned to take advantage of not only current but also future exascale machines.”

Support for this research came from the Exascale Computing Project, a collaborative effort of the DOE Office of Science and the National Nuclear Security Administration, the DOE Office of Science’s Biological and Environmental Research program, and the DOE Office of Science’s Advanced Scientific Computing Research program. The OLCF is a DOE Office of Science user facility.

i know we’re shifting into springtime but climate anxiety has me genuinely unsettled and nervous abt the temperature not being freezing anymore 😭 like i let out a big sigh of relief when i saw the forecast predicting snow this weekend as if i was seeing a negative pregnancy test. this is all almost exclusively ronald reagan’s fault i will not expand upon that

Southern California's persistent June gloom is finally clearing, but more rain is possible

June 12, 2023 - LA Times

The meteorologists are corroborating our findings of the relationship between June gloom and the suppression of the summer monsoon in Southern California. Of course, they don't know they're doing that, but this article says that with June gloom lifting, the rain is going to start. Fog and marine layer are the transmutation of the DOR used to suppress the monsoonal rain systems. When the DOR lifts, the seasonal rain resumes. This is why it's going to start raining once the transmutation process is completed!

Of course there is the usual meteorological disinfo regarding the reasons for the weather, but you can check out our latest video for the real discovery of why June gloom has started earlier, increased, and persisted longer, and how orgonite gifting is responsible.

After weeks of a particularly persistent bout of overcast weather as May gray dragged on into June gloom, forecasters are hopeful Southern California could see some clearing and warming by the end of this week.

“As the week goes on we have a slightly better chance of seeing peeks of sun," said David Sweet, a National Weather Service meteorologist based in Oxnard. "There’s a trough of low pressure that remains in the area through the week, but it gets weaker and weaker each day."

Any shift in the gloomy weather pattern will be gradual, Sweet noted, with temperatures still in the 60s for much of the region Monday — about 10 to 15 degrees below average. In some parts of San Diego County, daily low maximum temperature records were set Sunday, with Alpine and El Cajon reaching highs of only 58 and 63, breaking records from the 1960s.

“We’re looking at a weather pattern that is very favorable for the development of low clouds and fog," Sweet said. "It’s gloomy out there."...

I gotta say, guys, I’m genuinely sorry for people who hate hot weather and are currently in Northern Hemisphere summer, not only because this is your worst time, but also because you have people like me who are so excited for The Opposite Of Snow that we’re obnoxiously happy every single day about it.  I’m going to be insufferable.  I can’t help it.  I have shed fifteen layers of sweater and I’m giddy, and it’s just going to be like this for a while.
