Brazil Launches New Jaci Supercomputer for Advanced Climate and Weather Forecasting December 12, 2025 Brazil has taken a significant step forward in its scientific and environmental monitoring capabilities with the inauguration of a new high-performance supercomputer. The deployment marks a critical upgrade to the nation's technological infrastructure, enabling more precise modeling of complex climate systems and improved disaster preparedness. The new system, named Jaci, was officially launched this week at the National Institute for Space Research (INPE) facility in Cachoeira Paulista, São Paulo. The inauguration ceremony was led by Luciana Santos, Brazil's Minister of Science, Technology and Innovation, and Antonio Miguel Vieira Monteiro, the director of INPE. The name Jaci, chosen through a public vote, signifies the project's participatory nature. The supercomputer represents the first major milestone in the RISC Project (Renewal of INPE's Supercomputing Infrastructure), a multi-year initiative set to modernize the institute's Scientific Data Centre by 2028. The comprehensive plan includes installing new high-performance equipment, expanding electrical infrastructure, and implementing a photovoltaic plant to enhance energy efficiency. Jaci directly replaces the aging Tupã system, inaugurating a new era for weather and climate forecasting in the country. With its substantially greater processing capacity, the Jaci supercomputer will enable faster and more detailed weather forecasts and improve the accuracy of long-term climate simulations. This expanded computational power is crucial for operating MONAN, the new Brazilian Model for Ocean, Earth, and Atmosphere Forecasts, which is designed to represent South America's unique environmental conditions with unprecedented fidelity. The enhanced capabilities are expected to yield tangible benefits for environmental monitoring and natural disaster warning systems. By providing more robust scientific data, the system will contribute to better risk prevention strategies and inform the formulation of evidence-based public policies. As Antonio Miguel Vieira Monteiro noted, the system inaugurates a new stage in supercomputing for Brazil, directly supporting the nation's scientific and environmental sovereignty.
