Central Weather Bureau
The Central Weather Bureau is the national meteorological agency of the Republic of China (Taiwan), responsible for weather forecasting, seismic monitoring, climate observation, and tsunami warning. It provides services supporting aviation, maritime activities, agriculture, and civil protection, and collaborates with international organizations on atmospheric science and disaster risk reduction. The agency operates observational networks, research programs, and public communication systems that connect with regional centers and academic institutions.
History
The agency traces institutional roots to the late Qing dynasty reforms and the colonial period under Empire of Japan, when meteorological stations were established alongside ports such as Keelung and Kaohsiung. After the 1945 handover to the Republic of China, the organization was reorganized to integrate legacy facilities from the Japanese rule in Taiwan era and to respond to typhoon impacts like those recorded in the 1975 Typhoon Nina regional records. During the Cold War, coordination with the United States Weather Bureau and exchanges with the World Meteorological Organization helped modernize instrumentation and training. Following major events such as the 921 earthquake in 1999, the bureau expanded seismic monitoring capacity and strengthened ties with institutions including Academia Sinica, National Taiwan University, and the National Applied Research Laboratories.
Organization and Structure
The bureau is administratively placed under the Ministry of Transportation and Communications (Taiwan), with headquarters in Zhongzheng District, Taipei and regional offices across northern, central, southern, and eastern Taiwan. Its organizational divisions include forecasting, seismic monitoring, climate services, aviation meteorology, marine meteorology, and technical research, working alongside municipal partners such as the Taipei City Government and the Kaohsiung City Government. The leadership interacts with international bodies like the World Meteorological Organization and regional entities including the Japan Meteorological Agency and the Philippine Atmospheric, Geophysical and Astronomical Services Administration. The bureau engages with academic partners such as National Cheng Kung University and National Central University for curriculum development and workforce training.
Meteorological Services and Programs
Forecasting services cover synoptic, mesoscale, and tropical cyclone prediction, issuing advisories for aviation sectors like Taiwan Taoyuan International Airport and maritime stakeholders including the Port of Keelung. The bureau issues public forecasts, typhoon advisories, and marine warnings used by agencies like the Coast Guard Administration (Taiwan) and agricultural planners tied to Council of Agriculture (Taiwan). Specialized products include climatological datasets for Taiwan Strait fisheries and seasonal outlooks used by researchers at National Sun Yat-sen University. The bureau contributes to regional initiatives such as the ESCAP/WMO Typhoon Committee and participates in international campaigns like the Global Climate Observing System.
Observational Networks and Technology
The bureau operates a dense network of surface weather stations, upper-air sounding sites, Doppler weather radars, and automatic weather stations across islands including Penghu County and Kinmen County. Seismic arrays and tide gauges monitor earthquake and tsunami hazards near tectonic features like the Ryukyu Trench and the Eurasian Plate boundary. Remote sensing infrastructure includes satellite reception for platforms such as Himawari and radiosonde launches coordinated with World Meteorological Organization standards. The bureau's radar network integrates Doppler systems for convective monitoring used in coordination with the Taipei Weather Radar and regional radars maintained by the Japan Meteorological Agency and Hong Kong Observatory.
Research and Development
Research priorities include tropical cyclone dynamics, monsoon variability, urban meteorology for Taipei and Kaohsiung, and seismic risk assessment tied to studies at National Central University and Academia Sinica research centers. The bureau collaborates on numerical weather prediction with international modeling centers like the European Centre for Medium-Range Weather Forecasts and uses data assimilation techniques informed by academic partners such as National Taiwan University. Projects have produced peer-reviewed work in journals frequented by contributors from institutions including Peking University, University of Tokyo, and University of California, Los Angeles. Innovation programs have tested nowcasting systems, ensemble forecasts, and machine-learning approaches in cooperation with the Industrial Technology Research Institute.
Emergency Management and Public Warnings
The bureau issues time-sensitive warnings for typhoons, heavy rainfall, earthquakes, and tsunamis that feed into national emergency response systems such as the National Fire Agency (Taiwan) and local disaster task forces under the Executive Yuan. Alert dissemination uses multiple channels including cellular networks coordinated with telecommunications providers like Chunghwa Telecom and mass media outlets in Taipei and Kaohsiung. Joint exercises with the Central Emergency Operation Center (CEOC) and international partners such as the United States Agency for International Development enhance preparedness. Post-event analyses inform building resilience initiatives linked to the Council for Economic Planning and Development and infrastructure projects overseen by the Ministry of the Interior (Taiwan).
