This WMO project on world city forecasts is to explore the wider exchange and availability of official weather information on the Internet. In view of this, a WMO-sponsored web site - World Weather Information Service (WWIS) is established as a centralized source on the Internet for media to access official weather information issued by National Meteorological and Hydrological Services (NMHSs) efficiently and effectively. The WWIS web site is developed and maintained by the Hong Kong Observatory (HKO) of Hong Kong, China.
This global web site presents OFFICIAL weather observations, weather forecasts and climatological information for selected cities supplied by NMHSs worldwide. The NMHSs make official weather observations in their respective countries. Links to their official weather service web sites and tourism board/organization are also provided whenever available. Weather icons are shown alongside worded forecasts in this version to facilitate visual inspection.
The media are welcome to make information presented in this web site available to the public. When doing so, credit to the respective NMHSs should be given.
By December 2016, WWIS provided official weather information for 2123 cities in which 1993 cities are available with forecast from 135 members while 1953 cities are available with climatological information from 169 members. Suggestions to enrich the contents of this web site are welcome.
The Commission of Basic Systems (CBS) of World Meteorological Organization (WMO) at its Twelfth Session at Geneva, 27 November - 8 December 2000 discussed the need to strengthen the recognition of the public weather services that NMHSs provide through the setting up of a pilot project. The Commission agreed that a Collecting Center should be designated to collect weather forecasts supplied by participating NMHSs. The Collecting Center would generate an integrated product of major city forecasts around the world and make it available for use by all WMO Members for dissemination to the public and the media.
A WMO-sponsored web site - WWIS is set up to display the weather information supplied by participating NMHSs. The Commission agreed that Hong Kong, China, would take the lead in further developing the above concept and act as the Collecting Center.
By February 2005, four language versions emerged viz. English, Arabic, Chinese and Portuguese. At the CBS 13th Session at St. Petersburg, 23 February - 3 March 2005, the Commission agreed to turn the pilot project into an operational component of the Public Weather Services Programme and that the current host Members, viz. China; Hong Kong, China; Macao, China; and Oman, would continue to maintain the Chinese, English, Portuguese and Arabic versions of the WWIS web site respectively. The Commission also designated Hong Kong, China to serve as the coordinator of WWIS operation in collaboration with other WMO Members.
