| To predict the weather, modern meteorology depends upon near instantaneous exchange of weather information across the entire globe. Established in 1963, the World Weather Watch - the core of the WMO Programmes - combines observing systems, telecommunication facilities, and data-processing and forecasting centres - operated by Members - to make available meteorological and related environmental information needed to provide efficient services in all countries. |
|
| |
| PROGRAMME STRUCTURE |
| The World Weather Watch Programme comprises the design, implementation, operation and further development of the following three interconnected, and increasingly integrated, core components: |
|
|
| |
Consisting of facilities and arrangements for making meteorological observations (including climatological observations) and other related environmental observations at stations on land and at sea, and from aircraft, meteorological environmental satellites and other platforms. |
|
| |
Consisting of integrated networks of telecommunications facilities and services for the rapid, reliable collection and distribution of observational data and processed information. |
| |
|
| |
Consisting of World, Regional Specialized, and National Meteorological Centres that provide quality-assured, processed data, analyses, and forecast products on a wide range of temporal and spatial scales. |
|
|
| |
| Coordination, integration and efficient operation of the three core components are achieved through support programmes as follows: |
|
|
| |
Monitors and manages the information flow within the World Weather Watch system to assure quality and timely availability of data and products and the use of standard representation formats; |
|
| |
Provides specific technical guidance, training and implementation support. The WWW Operational Information Services supports cooperative initiatives. |
| |
| |
|
|
|
| |
| In addition, the WWW Programme incorporates three programmes that complement and enhance the core components of the WWW, as well as provide significant input and support to other WMO and co-sponsored Programmes: |
|
|
| |
Improves the quality and long-term stability of observations and measurements of meteorological and related environmental variables through the standardization activities and coordination and promotion of the use of efficient methods and technology to meet the requirements of operational and research applications |
|
| |
Assists NMHSs to respond effectively to large-scale atmospheric pollution and environmental emergencies in close collaboration with other relevant international organizations; |
|
| |
Coordinates the WWW basic systems implementation and operation in Antarctica to meet the requirements for meteorological services as well as for environmental monitoring and climate research. |
|
|
| |
| The World Weather Watch component systems are primarily managed under the technical responsibility of the Commission for Basic Systems (CBS) with the exception of the IMOP that is managed under the technical responsibility of the Commission for Instruments and Methods of Observation (CIMO). |
|
|
|
| |
|
|
| |
Assists Members in establishing national and regionally coordinated systems to ensure that the loss of life and damage caused by tropical cyclones are reduced to a minimum, and to achieve sustainable development. |
|
| |
Promotes wide availability and utilization of satellite data and products for weather, climate, water and related applications of WMO Members, and coordinates environmental satellite matters and activities throughout all WMO Programmes. |
|
| |
Whose principal aim is to strengthen the capabilities of WMO Members to meet the needs of society through provision and delivery of comprehensive weather and related environmental services, with particular emphasis on public safety and welfare, and to foster a better understanding by the public of the capabilities of their respective National Meteorological and Hydrological Services (NMHSs), and of how best to use the services that NMHSs deliver. |
