Korea Meteorological Administration WMO From weather prediction to air pollution research, climate change related activities, ozone layer depletion studies and tropical storm forecasting, the World Meteorological Organization coordinates global scientific activity to allow increasingly prompt and accurate weather information and other services for public, private and commercial use, including international airline and shipping industries. WMO's activities contribute to the safety of life and property, the socio-economic development of nations and the protection of the environment. Within the United Nations, the Geneva-based 187-Member Organization provides the authoritative scientific voice on the state and behaviour of the Earth's atmosphere and climate. The World Meteorological Convention, by which the World Meteorological Organization was created, was adopted at the Twelfth Conference of Directors of the International Meteorological Organization (IMO), which met in Washington in 1947. Although the Convention itself came into force in 1950, WMO commenced operations as the successor to IMO in 1951 and, later that year, was established as a specialized agency of the United Nations by agreement between the UN and WMO. The purposes of WMO are to facilitate international cooperation in the establishment of networks of stations for making meteorological, hydrological and other observations; and to promote the rapid exchange of meteorological information, the standardization of meteorological observations and the uniform publication of observations and statistics. It also furthers the application of meteorology to aviation, shipping, water problems, agriculture and other human activities, promotes operational hydrology and encourages research and training in meteorology.

Meteorology Workshop 16th APAN Meetings
Korea Meteorological Administration Data Collection or Product Centres Several dozen centres would serve as Data Collection or Product Centres (DCPC). Existing World Meteorological Centres and Regional/Specialized Meteorological Centres would function as DCPCs. However, many additional centres would also serve as DCPCs. This would include suppliers of special observations (e.g. ARGOS, ARINC), research projects, and centres producing products related to a specific discipline. DCPCs would: a.Collect special programme-related data and products as appropriate b.Collect information intended for dissemination only to NMHS within its area of responsibility (i.e. regional collections) c.Produce agreed data and products d.Provide information intended for global exchange to their responsible Global Information System Centre e.Disseminate information not intended for global exchange in whatever manner is agreed upon between the centre and the users of the product f.Provide facilities to collect observations from and disseminate products to the least developed NMCs within its area of responsibility (e.g. via e-mail) g.Support access to its products via WMO request/reply (“Pull”) mechanisms in an appropriate manner (i.e. dynamically-generated products would require around-the-clock connectivity to the Internet) h.Describe its products according to an agreed WMO standard and provide access to this catalogue of products or provide this information to another centre with this responsibility (e.g. a GISC) i.Ensure that they have procedures and arrangements in place to provide swift recovery or backup of their essential services in the event of an outage (due to, for example, fire or a natural disaster). j.May perform the functions of a National Centre Meteorology Workshop 16th APAN Meetings
Korea Meteorological Administration National Centres National Centres would form the foundation of the Future WMO Information System. Many National Centres would be part of an NMHS but others would have national responsibility for functions falling within WMO Programmes but located outside of the NMHS. The participation of the centres would be coordinated through the national Permanent Representative to WMO. National Centres would: a.Collect observational data from within their country b.Provide observations and products intended for global dissemination to their responsible GISC c.Provide observations and products intended for regional distribution to the responsible DCPC d.Collect, generate and disseminate products for national use Meteorology Workshop 16th APAN Meetings

Korea Meteorological Administration Impact and Benefit of APCN • The practical importance of climate forecasts for the protection of life and property, together with concerns about environmental change, have led to the initiation of the APCN. The project’s most important challenge is to provide accurate and reliable climate information for member economies in the Asian-Pacific region. The range of seasonal forecasts and detailed climate information required and provided will be developed through dialogue between Scientific Steering Committee, the scientists involved in each component of the project, and NHMSs and other participating institutes in member economies. Meteorology Workshop 16th APAN Meetings
Korea Meteorological Administration Impact and Benefit of APCN • The results of the project will benefit both public and private meteorological and hydrological institutions in the Asia-Pacific region in several ways. Those institutions without the capacity to produce climate predictions will be able to access optimized, high-cost global climate predictions. Sectors likely to benefit will include agriculture, forestry, health, energy, and water management. In addition, manufacturing industries like clothing, heating and air-conditioning may be beneficiaries. Most of all, the greatest benefit from this project will be the reduction of economic and human loss due to natural disasters caused by unusual weather and climate. The predictions should enable national and international disaster prevention offices to respond more effectively to natural disasters and mitigate economic losses in the case of extreme climate events.
