National Conference on Observational and Numerical aspects of Compound Events (ONCE)

This Conference calls for original research that tackles these urgent challenges. We invite contributions on the dynamics, forecasting, and risk assessment of compound extreme events, as well as strategies for adaptation and mitigation. Studies integrating modeling, theory, and observational data are especially encouraged. Together, we can shape a clearer understanding of these escalating threats-and chart pathways to reduce their impact. Keeping this in view, ONCE-2026 deliberates on the following subthemes:

• Compound extreme events: Diverse approaches by observations and numerical modeling
• Concurrent Events over the Indian subcontinent
• Sequential or persistent compound extreme events
• Impact of land use and land cover changes on compound events
• Analysis and prediction of compound extremes using AI/ML/DL techniques etc.
• Systemic Risk: Identification, Response and Societal Feedbacks in disaster risk reduction
• Roles of oceanic and atmospheric processes in the development of compound extremes
• Compound extremes and Air Pollution Interactions
• Impact of compound extremes on Agriculture, livestock, fisheries
