Developed and operated by the Hong Kong Observatory (HKO) on behalf of the WMO, the website provides official weather forecasts for 1 719 cities around the world supplied by 133 WMO Members. It is available in ten languages: Arabic, Chinese, English, French, German, Italian, Polish, Portuguese, Russian and Spanish.
“The World Weather Information Service is the authoritative source of official forecasts from around the globe. It is an excellent example of international collaboration between meteorological services to better serve the public worldwide. National weather services operate standardized weather observing networks and follow the most rigorous forecasting procedures,” said WMO Secretary-General Michel Jarraud.
“A five-day forecast today is as accurate as a two-day forecast 25 years ago thanks to cutting-edge science and powerful super computers. Meteorological services are constantly improving the lead-time and reliability of their predictions. The new web design will ensure that the weather information will be available in a more user-friendly manner.”
The Director of the HKO, Mr Shun Chi-ming said, “We are privileged to have the opportunity to collaborate with WMO in this endeavor. We are very happy to bring new features to the website to provide better weather service to the public and international media.”
In addition to a brand-new user interface, the website was integrated with latest web technology including Geographical Information Systems (GIS) to provide a number of user-friendly new features such as user-customized homepage, a favorite list of cities, a tool for sharing weather forecasts with friends, and news from WMO, etc. Meanwhile, to provide smoother user experience, the website will be switched to the newly created mobile version automatically if users visit the website with mobile devices.
Since its launch in 2002, the cumulative total number of page views to the website has reached 1.3 billion with a record high of about 173 million in 2013 alone - an average of more than 12 million per month. WWIS is also available as an App, viz. MyWorldWeather, for iPhones and Android phones.
