The Brazilian government has launched a new supercomputer.

The Minister of Science, Technology and Innovation, Luciana Santos, and the director of the National Institute for Space Research (INPE), Antonio Miguel Vieira Monteiro, inaugurated the Jaci supercomputer this week at the INPE unit in Cachoeira Paulista, in the interior of São Paulo.

Jaci is a high-performance device designed for scientific applications and represents a significant advance for the national technological infrastructure. The name was chosen by popular vote, reinforcing the participatory nature of the project.

The new system replaces the Tupã supercomputer and inaugurates a new stage in supercomputing for weather and climate forecasting in Brazil. With greater capacity than the previous model, Jaci will enable faster and more detailed weather forecasts, as well as improve the accuracy of climate simulations.

Among the expected benefits are advances in environmental monitoring and improved support for natural disaster warning systems, contributing to risk prevention and the formulation of public policies based on more robust scientific data.

The Jaci supercomputer represents the first major milestone in the RISC Project (Renewal of INPE's Supercomputing Infrastructure), an initiative that plans to modernize the National Institute for Space Research's Scientific Data Centre by 2028. The plan includes the installation of new high-performance equipment, the expansion of the electrical infrastructure, and the implementation of a photovoltaic plant to ensure greater energy efficiency.

With the expanded capacity, it will be possible to put MONAN, the new Brazilian Model for Ocean, Earth, and Atmosphere Forecasts, into operation. Developed to represent South America's environmental conditions more accurately, the system should improve the quality of weather and climate forecasts, as well as contribute to studies on environmental changes in the region.
