Machine Learning Improves Weather and Climate Models

eos.org | April 07, 2020

Both weather and climate models have improved drastically in recent years, as advances in one field have tended to benefit the other. But there is still significant uncertainty in model outputs that are not quantified accurately. That’s because the processes that drive climate and weather are chaotic, complex, and interconnected in ways that researchers have yet to describe in the complex equations that power numerical models.Historically, researchers have used approximations called parameterizations to model the relationships underlying small-scale atmospheric processes and their interactions with large-scale atmospheric processes. Stochastic parameterizations have become increasingly common for representing the uncertainty in subgrid-scale processes, and they are capable of producing fairly accurate weather forecasts and climate projections. But it’s still a mathematically challenging method. Now researchers are turning to machine learning to provide more efficiency to mathematical models.Here Gagne et al. evaluate the use of a class of machine learning networks known as generative adversarial networks (GANs) with a toy model of the extratropical atmosphere—a model first presented by Edward Lorenz in 1996 and thus known as the L96 system that has been frequently used as a test bed for stochastic parameterization schemes. The researchers trained 20 GANs, with varied noise magnitudes, and identified a set that outperformed a hand-tuned parameterization in L96. The authors found that the success of the GANs in providing accurate weather forecasts was predictive of their performance in climate simulationsThe GANs that provided the most accurate weather forecasts also performed best for climate simulations, but they did not perform as well in offline evaluations.

WNS Releases Global Data & Analytics Survey

WNS | February 21, 2022

WNS Limited, a leading provider of BPM (Business Process Management) solutions, unveiled a survey report with the title Time to Accelerate your Data & Analytics Journey is Now, which explores the maturity of data and analytics abilities as well as the future outlook across industries. The report, which was based on a WNS-commissioned survey performed by Forrester Consulting, was designed to look at the role of data, analytics, & Artificial Intelligence in assisting businesses in achieving their strategic goals, as well as the difficulties they face in becoming a data-driven company. The study included 450 CXOs and senior decision-makers from important industries such as banking and financial services, insurance, life sciences, consumer packaged goods, manufacturing, retail, and new-age digital/ hi-tech industries from the United States, Europe, and the Asia Pacific. While 63% of decision-makers perceive data and analytics as a crucial strategic enabler, just 37% prioritize investment in enhanced data and analytics capabilities, according to the report. This emphasizes the immense possibility of acting on corporate goals in the future. Importantly, 68% intend to expand internal capabilities, hire more people, and use cloud and data commercialization solutions. The report emphasizes the importance of cloud-based analytics in helping businesses achieve agility and scalability. Today, 31% of respondents are in the midst of transitioning to a cloud-first strategy, with cloud-based analytics capabilities being a top priority in their plan. Businesses are prioritizing investment in data fabric/virtualization technologies, Data Lake, and data stream processing to promote increased data and analytics maturity. Higher-maturity organizations are putting more effort into building cloud-based analytics capabilities. "According to the survey, 82 percent of organizations with an advanced maturity level have experienced positive year-on-year growth over the past three years. Clearly, data and analytics maturity, including robust AI and cloud-based solutions, is a key enabler of business performance and organizational resilience in the new normal. At WNS Triange (formerly WNS' Research and Analytics Unit), we are partnering with global businesses in their data-to-insights journey by leveraging the power of domain, AI / ML and intelligent cloud platforms to co-create future-ready solutions."
