Typhoon Committee (ESCAP/WMO) is an intergovernmental body established to promote cooperation in meteorology, hydrology and disaster risk reduction across the Asia‑Pacific region. It brings together national meteorological and hydrological services and disaster management agencies to coordinate standards, forecasting, preparedness and post‑event assessment for tropical cyclones. The Committee operates under the joint auspices of the United Nations Economic and Social Commission for Asia and the Pacific and the World Meteorological Organization, engaging a broad range of regional partners and multilateral institutions.

Overview and history

The Committee was established in 1968 following discussions among Japan, United States, United Kingdom, Philippines, China, and other regional actors to address recurrent tropical cyclone impacts in the North Pacific Ocean and South China Sea. Early sessions convened experts from Hong Kong, Taiwan, Republic of Korea, Thailand, and Vietnam to harmonize warnings and storm surge guidance. Over decades the Committee expanded its remit in parallel with initiatives such as the Hyogo Framework for Action, the Sendai Framework for Disaster Risk Reduction, and collaborations with agencies like the Asian Development Bank and United Nations Environment Programme. Key historical milestones include the adoption of unified storm nomenclature practices, the establishment of regional databases, and the integration of satellite era capabilities led by partners such as NASA, NOAA, and the European Space Agency.

Membership and governance

Membership comprises national members from East Asia, Southeast Asia and the Pacific, including China, Japan, Republic of Korea, Philippines, Thailand, Viet Nam, Malaysia, Indonesia, Cambodia, Lao People's Democratic Republic, Myanmar, Bangladesh, India, Sri Lanka, Pakistan, Nepal, Bhutan, Mongolia, Hong Kong, and Pacific members associated through Secretariat of the Pacific Regional Environment Programme. Governance features an annual session, a Bureau, and a Secretariat hosted by ESCAP and WMO offices in Bangkok. The Bureau includes positions such as Chair, Vice‑Chair and Rapporteur elected from member delegations, with technical panels reporting to plenary sessions. External partners include UNDP, World Bank, Asian Disaster Preparedness Center, and regional research institutions like the International Research Institute for Climate and Society.

Mandate and functions

The Committee’s mandate covers tropical cyclone observation, forecasting, warning dissemination, preparedness, mitigation and post‑disaster recovery coordination. It develops regional guidance for tropical cyclone forecasting centers, storm surge modeling, and early warning systems in concert with national meteorological and hydrological services such as Japan Meteorological Agency, China Meteorological Administration, Philippine Atmospheric, Geophysical and Astronomical Services Administration, and Korea Meteorological Administration. It supports harmonization of warning protocols consistent with WMO standards and assists implementation of regional elements of the Sendai Framework for Disaster Risk Reduction. The Committee also coordinates with humanitarian actors like International Federation of Red Cross and Red Crescent Societies, Oxfam, and Care International for mass evacuation and relief planning.

Meetings and technical cooperation

Annual sessions assemble delegations, including directors and technical experts, to review past seasons, approve projects, and set priorities. Technical cooperation occurs through panels on meteorology, hydrology, disaster risk reduction and public education, engaging institutions such as Meteorological Research Institute (Japan), Indian Institute of Tropical Meteorology, CSIRO, and Chinese Academy of Sciences. Joint exercises, like multi‑country forecast drills and surge inundation workshops, involve satellite data providers (NOAA》, JAXA), numerical modeling centers, and communications partners including International Telecommunication Union. Project financing and implementation have been supported by grants from the Asian Development Bank, bilateral aid agencies such as JICA and USAID, and multilateral funds.

Products, services and standards

The Committee issues regional guidance documents, standard operating procedures, best practice manuals, and a joint annual report on tropical cyclone activity. It promulgates model formats for warning bulletins, storm surge advisories, impact-based forecasting templates, and data exchange protocols compatible with WMO Information System standards. Collaborative products include joint storm best‑track datasets, regional risk atlases, and interoperable metadata catalogues leveraging standards from Global Telecommunication System and Space Weather initiatives. The Committee also endorses technical standards for observation networks, automatic weather stations, Doppler radar siting, and ocean buoy deployments coordinated with agencies like CSIR, National Oceanic and Atmospheric Administration, and regional hydrographic offices.

Capacity building and training

Capacity building is delivered through regional training courses, fellowships, and exchange visits targeting forecasters, hydrologists, emergency managers and communication officers. Training partners include World Bank GROUP technical teams, UNISDR offices, university programmes at National University of Singapore, University of the Philippines, Peking University, and research collaborations with Met Office (UK). Programs emphasize numerical weather prediction, ensemble forecasting, impact‑based early warning, community preparedness, and use of satellite remote sensing from satellite operators such as EUMETSAT and GCOM. Scholarships, tabletop exercises, and knowledge‑transfer workshops strengthen national capacities to implement standards and to integrate climate change adaptation promoted by Intergovernmental Panel on Climate Change assessments.

Impact and notable initiatives

The Committee has contributed to reduced cyclone fatalities in several member countries through improved warning lead times, standardized communications, and adoption of surge forecasting tools. Notable initiatives include the development of the Joint Typhoon Warning Center partnerships, regional storm surge pilot projects funded by the Asian Development Bank, the establishment of multi‑country best‑track archives, and public awareness campaigns modeled on successful programmes in Japan and Philippines. Collaborative research spawned advances in coupled atmosphere‑ocean modeling, community‑based early warning systems, and urban flood resilience projects in megacities like Manila and Bangkok. Ongoing work focuses on enhancing real‑time data sharing, climate resilience measures linked to Paris Agreement commitments, and integration with regional disaster financing mechanisms such as the ASEAN Coordinating Centre for Humanitarian Assistance on disaster management.
