Numerical weather prediction is a computationally expensive task that requires not only the numerical solution to a complex set of non-linear partial differential equations, but also the creation of a parameterization scheme to estimate sub-grid scale phenomenon.

UCAR collaboration with The Weather Company to improve weather forecasts worldwide

BOULDER, Colo. — The University Corporation for Atmospheric Research (UCAR) today announced a new collaboration with The Weather Company, an IBM business, to improve global weather forecasting. The partnership brings together cutting-edge computer modeling developed at the National Center for Atmospheric Research (NCAR) with The Weather Company's meteorological science and IBM's advanced compute equipment."This is a major public-private partnership that will advance weather prediction and generate significant benefits for businesses making critical decisions based on weather forecasts," said UCAR President Antonio J. Busalacchi. "We are gratified that taxpayer investments in the development of weather models are now helping U.S. industries compete in the global marketplace."UCAR, a nonprofit consortium of 110 universities focused on research and training in the atmospheric and related Earth system sciences, manages NCAR on behalf of the National Science Foundation.With the new agreement, The Weather Company will develop a global forecast model based on the Model for Prediction Across Scales (MPAS), an innovative software platform developed by NCAR and the Los Alamos National Laboratory.The Model for Prediction Across Scales (MPAS) enables forecasters to combine a global view of the atmosphere with a higher-resolution view of a particular region, such as North America. (@UCAR.

Unlike traditional three-dimensional models that calculate atmospheric conditions at multiple points within a block-shaped grid, it uses a hexagonal mesh resembling a honeycomb that can be stretched wide in some regions and compressed for higher resolution in others. This enables forecasters to simultaneously capture far-flung atmospheric conditions that can influence local weather, as well as small-scale features such as vertical wind shear that can affect thunderstorms and other severe weather.Drawing on the computational power of GPUs — graphics processing units — such as those being used in a powerful new generation of IBM supercomputers, and on the expertise of NCAR and The Weather Company, the new collaboration is designed to push the capabilities of MPAS to yield more accurate forecasts with longer lead times. The results of NCAR's work will be freely available to the meteorological community. Businesses, from airlines to retailers, as well as the general public, stand to benefit.Mary Glackin, head of weather science and operations for The Weather Company, said, "As strong advocates for science, we embrace strong public-private collaborations that understand the value science brings to society, such as our continued efforts with UCAR to advance atmospheric and computational sciences.""Thanks to research funded by the National Science Foundation and other federal agencies, society is on the cusp of a new era in weather prediction, with more precise short-range forecasts as well as longer-term forecasts of seasonal weather patterns," Busalacchi said. "These forecasts are important for public health and safety, as well as enabling companies to leverage economic opportunities in ways that were never possible before."About The Weather CompanyThe Weather Company, an IBM Business, helps people make informed decisions and take action in the face of weather. The company offers weather data and insights to millions of consumers, as well as thousands of marketers and businesses via Weather’s API, its business solutions division, and its own digital products from The Weather Channel (weather.com) and Weather Underground (wunderground.com).This webpage was last updated on July 5, 2017.

Promoting diversity in high-performance computing

May 2, 2017 | Justin Moore was supporting his family of four with a job at an auto parts store while juggling classes at Salish Kootenai College, a Native American college in Montana, when he heard about a computing internship in 2014 at the National Center for Atmospheric Research (NCAR) in Boulder, Colo.The internship, which used a small, low-cost computer called Raspberry Pi to teach key concepts of high-performance computing, quickly paid off. Today, Moore works full-time as an IT network specialist at Energy Keepers Inc., which manages the hydroelectric plant on the Flathead Indian Reservation in Montana, while he continues to chip away at his degree."I believe the skills I obtained in the internship can be directly attributed to my success in my field," Moore said. "It also gave me the chance to network with some of the brightest minds in the country."Justin Moore turned a summer internship at NCAR into a full-time computer networking job at a hydroelectric plant on the Flathead Indian Reservation in Montana. (©UCAR.

In March, in efforts to reach more students, NCAR pivoted to an "externship" model, bringing the Raspberry Pi training to Miami Dade College faculty who can teach the skills to dozens of students at a time. “Raspberry Pi is a perfect platform for high-performance computing education because the credit-card sized mother boards can be linked together to mimic the parallel processing capabilities of a supercomputer and perform simplified geoscience applications,” said Rich Loft, director of technology development in NCAR's Computational and Information Systems Laboratory.A Raspberry Pi, which costs $35 or less, can run a full Linux operating system — the same system used by nearly all supercomputers, in more than 90 percent of smartphones, and in many other electronic devices.A Raspberry Pi kit used during the NCAR training at Miami Dade College.

Components plug into a breadboard in the center of the picture (Photo courtesy Rich Loft, NCAR.)"It's inexpensive. It levels the playing field," said Loft, who led the training at Miami Dade College. "In my view it busts the digital divide."Loft noted that the previous internship approach wasn't reaching as many students as NCAR had hoped, partly because many students found it too difficult to relocate to Boulder during the summer. Miami Dade proved an ideal testbed for an externship model, since it's one of the country's largest universities, with eight campuses and more than 90,000 students, 70 percent of whom are Hispanic and 17 percent of whom are African American."This approach has scalability," Loft said, shortly after returning from the intensive two-day faculty workshop. "You can't scale up a program training one student at a time, even though it's very rewarding."The NCAR directorate, which supported the Miami Dade training through a diversity grant, hopes that an expanded program will reap even greater outcomes.A legacy of successThe Raspberry Pi internship approach already has yielded additional success stories, with students going on to graduate school and receiving prestigious scholarships.Lauren Patterson, for example, was a student at Hampton University in Virginia when she learned Raspberry Pi as a SIParCs intern at NCAR, also in 2014. "I loved that I was able to work hands-on and assemble the Raspberry Pi cluster myself," Patterson said.Lauren Patterson has received an Apple scholarship and will start a job at Google after completing her summer internship on Raspberry Pi at NCAR. (@UCAR. Photo by Carlye Calvin. This image is freely available for media & nonprofit use.) She said her experience led to an Apple internship under its scholars program, a $25,000 scholarship, and a software engineering job at Google starting next fall in New York City. Apple scholars participate in a 12-week internship at Apple headquarters in California, receive ongoing coaching and guidance, and serve as Apple ambassadors on their campuses.Gaston Seneza, a senior at Philander Smith College in Arkansas, said that before NCAR's SIParCS 2015 internship he had no practical knowledge of computers.He learned about Linux, sensors, programming, cloud storage, and scientific research, and now has a passion for computer science. "Raspberry Pi was a game-changer for me," he said.Gaston Seneza, who is from Rwanda, also won an Apple scholarship after his summer internship at NCAR. (@UCAR. Photo by Carlye Calvin. This image is freely available for media & nonprofit use.) The Rwandan native also was named an Apple scholar, and aspires to go into the field of artificial intelligence. "My dream is to see a world where intelligent machines work for us."Said Loft: "We're trying to get these kids on the hi-tech career onramp. You put machine learning or experience with parallel computing on your resume and you can get hired by Apple, Google, or Amazon – or get into graduate school. These are hot skills." Machine learning is a type of artificial intelligence in which a computer program can change or "learn" as it encounters new data.Moore, Patterson, and Seneza all praised the mentoring by Loft, an NCAR senior scientist, and Raghu Raj Prassana Kumar, an NCAR project scientist who has worked with the Raspberry Pi training project since its beginning."It's a lot of fun, and it's very rewarding to help these young people learn," Kumar said.Kumar is also known at NCAR for creative uses of Raspberry Pi, including connecting 12 of them to calculate Pi to a million digits on Pi Day in 2015. (It took longer than a day and one Raspberry Pi burned out from exertion, but it was successful.)Connecting learning to everyday lifeAt the recent Miami Dade workshop, Kumar and Loft, along with University of Wyoming Professor Suresh Muknahallipatna and three of his students, taught 20 Miami Dade faculty members how to set up and program simple projects with a Raspberry Pi. One group used sensors to measure things like temperature, pressure, and humidity, while another created a word frequency histogram from the complete works of William Shakespeare using a Raspberry Pi Hadoop cluster.Ana Guzman (far right), a Miami Dade College associate professor of electricial engineering, gets Raspberry Pi tips from Cena Miller, a University of Wyoming student.

(Photo courtesy Rich Loft, NCAR.) David Freer, a Miami Dade computer science professor, said he and his colleagues thought the workshop was terrific. "We worked with flame sensors that sent messages to users on their cell phones, along with other cool projects," he said.Djuradj Babich, director of Miami Dade's School of Engineering and Technology, said he hopes to "ride the excitement wave" from the training and develop an ongoing relationship with NCAR. Loft said NCAR also hopes to reach out to additional universities.Qiong Cheng, an assistant professor at Miami Dade, has since set up a Raspberry Pi in her office, complete with a motion detector. She said she will use the Raspberry Pi platform in her classes this fall, which are part of a new bachelor's program in data analytics.She likes the fact that Raspberry Pi, combined with sensors, is an inexpensive way to measure data in the real world, and thus connect learning to everyday life.  "Students are more interested in that," she said, adding that Raspberry Pi supports "our mission to reach underrepresented students — to motivate them, to inspire them, and to provide them with a hands-on learning experience."That's the kind of talk that excites Loft."We want to continue to collaborate to drive this home. Which means that Miami Dade is using this in their curriculum as the workhorse in their computer lab for students," he said. "That's what's going to make me very happy."Writer/Contact:Jeff Smith, Science Writer and Public Information Officer
