China unveils MAZU weather early warning device at COP31

China unveiled a compact weather early warning device at the COP31 climate conference in Antalya, Türkiye, on November 11, sharing its technology to help prevent and reduce the impact of weather-related disasters.

The device, part of China's MAZU intelligent early warning solution, was introduced through a promotional video at the High-Level Forum on South-South Cooperation on Climate Change.

Combining hardware and software in a single unit, it is designed to help developing countries deploy MAZU locally and readily incorporate data from their own weather observations.

The unit integrates data storage, AI processing, networking, display and computing functions, and supports Ethernet, 5G and satellite communications.

Its tools include forecasts for the immediate hours ahead and the short term, a dashboard providing an overview of key information, operational monitoring and on-site AI assistance.

The device can operate independently on site or connect to cloud resources and work with existing operational systems. It also supports modular expansion and ongoing upgrades, helping countries quickly strengthen their early warning capabilities.

As of October 2026, the broader MAZU solution had been deployed in eight countries, including Pakistan, Ethiopia and Sri Lanka, with cloud-based trials underway in more than 50 countries. It provides a public service for disaster prevention and risk reduction worldwide, helping strengthen local capabilities.
