Thepurposes of WMO are to facilitate international cooperation in theestablishment of networks of stations for making meteorological,hydrological and other observations; and to promote the rapid exchangeof meteorological information, the standardization of meteorologicalobservations and the uniform publication of observations andstatistics. It also furthers the application of meteorology toaviation, shipping, water problems, agriculture and other humanactivities, promotes operational hydrology and encourages research andtraining in meteorology.As of June 1996, there were 185 Members, comprising 179 Member Statesand six Member Territories, all of which maintain their ownMeteorological and Hydrological Services.Major WMO Programs include:- World Weather Watch ('http://www.wmo.ch/web/www/www.html')- World Climate Programme ('http://www.wmo.ch/web/wcp/wcp-home.html')- Applications of Meteorology Programme ('http://www.wmo.ch/web/aom/aom.html')- World Climate Research Programme ('http://www.wmo.ch/web/wcrp/wcrp-home.html')- Global Climate Observing System ('http://www.wmo.ch/web/gcos/gcoshome.html')- Atmospheric Research and Environment Programme ('http://www.wmo.ch/web/arep/arep-home.html')- Hydrology and Water Resources Programme ('http://www.wmo.ch/web/homs/hwrphome.html')- Education and Training Programme ('http://www.wmo.ch/web/etr/etrp98.html')For more information:WMO7 bis Avenue de la PaixCP-2300 - 1211 Geneva 2 - SwitzerlandTel: +41 22 730 8111Fax +41 22 730 8181Tlx: 414199A OMM CHE-mail: ipa@www.wmo.ch
