Parent agency	Ministry of Natural Resources and Environment

Vietnam Meteorological and Hydrological Administration is the national authority responsible for meteorological, hydrological, climatological, and oceanographic services in Vietnam. It operates under the Ministry of Natural Resources and Environment and coordinates with regional bodies, research institutes, and international organizations such as the World Meteorological Organization, United Nations Development Programme, and Asian Development Bank. The agency provides forecasts, warnings, and data used by stakeholders including the Vietnam People's Army, Vietnam National Shipping Lines, and provincial authorities in Hanoi, Ho Chi Minh City, and the Mekong Delta.

History

The administration traces its origins to early 20th-century observatories established during the French Indochina period and successor institutions after the August Revolution. Post-1954 restructuring following the Geneva Conference (1954) and later reforms during the Đổi Mới era reorganized meteorological and hydrological services to support national reconstruction, agricultural modernization in the Red River Delta and Mekong Delta, and disaster risk reduction after major events like Typhoon Linda and Typhoon Nari. Throughout the late 20th and early 21st centuries the agency aligned with global standards set by the World Meteorological Organization and integrated practices from programs such as the Global Climate Observing System and Intergovernmental Panel on Climate Change reports to respond to accelerating sea-level rise in the South China Sea and flood hazards in the Hương River basin.

Organization and Structure

The administration is organized into national centers, regional meteorological and hydrological centers, provincial stations, and specialized institutes reporting to the Ministry of Natural Resources and Environment. Key components include a national forecasting center, a hydrology center, a climate monitoring center, and an observational network management office that liaises with agencies such as the Vietnam Institute of Meteorology, Hydrology and Climate Change and universities like Vietnam National University, Hanoi and Can Tho University. It maintains operational relationships with the Vietnam Red Cross Society, Vietnam Airlines, and maritime authorities including the Vietnam Maritime Search and Rescue Coordination Center.

Functions and Services

Primary functions include short- to long-range forecasting, flood forecasting for river basins including the Mekong River and Red River (Hồng Hà), typhoon tracking in the Pacific Ocean and South China Sea, and climate monitoring supporting adaptation planning by ministries such as the Ministry of Agriculture and Rural Development (Vietnam). Services extend to aviation meteorology for airports like Noi Bai International Airport and Tan Son Nhat International Airport, marine forecasts for ports like Hai Phong Port and Saigon Port, agro-meteorological advisories for rice producers in An Giang Province, and hydrometeorological early warning disseminated through national media outlets including VTV and provincial disaster committees.

Observing Network and Technology

The observing network comprises surface synoptic stations, automatic weather stations, river gauge networks, tide gauges along the South China Sea coast, Doppler weather radars, and upper-air sounding sites. The agency operates modeling and prediction systems that incorporate global models such as the ECMWF and GFS and regional models adapted from projects like the WMO's Severe Weather Forecasting Demonstration Project. Technology upgrades have involved partnerships for satellite data reception used by operators of VINASAT ground stations, installation of Automatic Weather Station networks for remote provinces, and modernization of hydrological telemetry systems to monitor basins like the Cả River.

Research and Development

R&D priorities include climate change impact assessment for sea-level rise affecting the Red River Delta and Da Nang, improved numerical weather prediction tuned to monsoon dynamics of the South China Sea, and hydrological modeling for floodplain management in the Mekong Delta. The administration collaborates with domestic research bodies such as the Vietnam Academy of Science and Technology and international partners including the National Oceanic and Atmospheric Administration, Japan Meteorological Agency, and Australian Bureau of Meteorology to develop capacity in seasonal forecasting, remote sensing, and climate downscaling used by planners in provinces like Quảng Ninh and Thừa Thiên–Huế.

International Cooperation and Agreements

The administration participates in multilateral frameworks including the World Meteorological Organization World Weather Watch, the Asia-Pacific Economic Cooperation cooperative efforts on disaster resilience, and bilateral memoranda with agencies such as the Japan Meteorological Agency and Korea Meteorological Administration. It contributes to regional mechanisms like the Greater Mekong Subregion environmental projects and engages with UNICEF and UNFCCC initiatives for adaptation funding and technical assistance in implementing national communications and climate strategies.

Controversies and Public Impact

Controversies have arisen over forecast accuracy during high-impact events, data transparency in hydro-meteorological records, and timeliness of warnings during floods affecting provinces such as Quảng Ninh and An Giang Province. Debates in the National Assembly and among stakeholders including the Vietnam Farmers' Union and media outlets have pressured further investment in observing networks and modeling. Public impact includes essential contributions to disaster risk reduction that have reduced losses from storms affecting cities like Da Nang and Nha Trang and supported sectors from fisheries in Phú Quốc to hydropower operations on the Sông Đà.
