Four Chinese weather stations have been included in a new batch of World Meteorological Organization (WMO) Centennial Observing Stations, bringing the total number of WMO-recognized centennial weather stations in China to 22.

The recognition was discussed during the 80th session of the WMO Executive Council in Geneva, Switzerland, from June 22 to 26.

The newly recognized stations are seperately located in Guiyang in southwest China's Guizhou Province, Tanggu in north China's Tianjin Municipality, Tengchong in southwest China's Yunnan Province, and Yueyang in central China's Hunan Province.

All four stations have maintained continuous weather observations for more than a century. Observations at the Tanggu and Yueyang stations began in 1909, while the Tengchong station started operations in 1911 and the Guiyang station in 1920.

Through decades of continuous observations, the stations have accumulated long-term and stable meteorological data of significant scientific value. The data have provided essential support for studying climate change patterns in different regions of China, monitoring extreme weather and climate events, and improving weather forecasting services.
