Understanding the WMO Joint Advisory Group on AI
The WMO, a specialized UN agency coordinating global efforts on weather, climate, and water, launched JAG-AI in 2025 to harness artificial intelligence responsibly. Comprising experts from academia, industry, and public sectors, the group advises on integrating AI into meteorological infrastructures. Objectives include accelerating AI adoption for precise forecasting, ethical data use, and bridging gaps between physics-based and data-driven models.
JAG-AI reports to WMO's Infrastructure Commission and Research Board, focusing on standards for AI trustworthiness, interoperability of models, and capacity building in developing nations. Mengaldo's role involves shaping guidelines for AI-enhanced early warning systems, vital as extreme weather events rise. For instance, AI can now predict sub-seasonal patterns with unprecedented speed, aiding disaster preparedness.
This group emerges amid rapid AI progress in weather tech, like Google's GraphCast and ECMWF's AIFS, which rival traditional supercomputer simulations. Yet, challenges persist: AI models often falter in rare events or data-scarce regions like the tropics, where Singapore's expertise shines. Mengaldo's involvement ensures Asian perspectives, especially tropical dynamics, inform global standards. Learn more about WMO's AI strategy here.
Mengaldo's Expertise Aligns Perfectly with WMO Priorities
Mengaldo's research excels in hybrid models fusing physics equations with neural networks, preventing drift in extended forecasts. A recent NUS project led by him developed an AI technique maintaining simulation stability over decades, outperforming conventional methods by preserving energy conservation and physical laws. This is pivotal for climate scenarios under IPCC pathways, where long-horizon accuracy informs policy.
In weather contexts, his work on explainable emulators reveals why AI makes certain predictions, demystifying black-box limitations. For Singapore, prone to thunderstorms and haze, such tools could refine nowcasting. MathEXLab collaborations with international partners, including ECMWF, have already yielded open-source tools like PyTorch-based climate emulators, democratizing access.
Statistics underscore the impact: AI weather models now achieve 90-95% accuracy for medium-range forecasts, up from 80% in physics-only systems, per recent benchmarks. Mengaldo's contributions position NUS researchers to influence WMO's push for equitable AI deployment globally.
Singapore's Higher Education Leading AI-Climate Nexus
NUS's appointment of Mengaldo mirrors broader Singapore university thrusts in AI for sustainability. The Climate and Weather Research Alliance Singapore (CAWRAS), uniting NUS, NTU Singapore, A*STAR, and NEA, channels $25 million via the Weather Science Research Programme (WSRP). Launched in 2025, it targets tropical urban weather prediction using AI foundation models and urban climatology.
NUS strengths in hydroclimatology and AI modeling complement NTU's Earth Observatory collaborations. For students, this means enriched curricula: NUS offers modules in computational climate science, attracting global talent. Singapore's National AI Strategy 2.0 allocates resources for 100,000 AI upskilled workers by 2025, with universities central.
