The Hong Kong Observatory Open Day 2017, echoing this year's World Meteorological Day theme of "Understanding Clouds" (, was successfully held on 25 and 26 March with nearly 14,000 visitors attending the event. In a packed programme attended by more than 500 participants on the morning of 25 March at Tsim Sha Tsui District Kai Fong Welfare Association, a seminar on "Understanding Clouds" introducing the new cloud types was followed by an award presentation ceremony for the "Meteorological Information Technology Design Invention Competition", jointly organized by the Observatory and Po Leung Kuk Cheung Hong Youth Development Centre (sponsored by Rotary Club of City Northwest Hong Kong). Participants also included youngsters from the 18 districts, youth uniformed groups as well as members from "Friends of the Observatory" and "Community Weather Observing Scheme".

The Open Day exhibition at the Observatory Headquarters focused on the new web-based version of the "International Cloud Atlas" (ICA) developed by the Observatory on behalf of the World Meteorological Organization ( Nearly 60 photos taken by members of the public in Hong Kong including Observatory staff and adopted by ICA were on display. The exhibition also presented the evolution of tropical cyclone signals over the past 100 years. During the Open Day, the TV weather presenters from the Observatory gave live demonstration of weather reporting, while the Director of Hong Kong Observatory attended autograph sessions and posed for photos with visitors. Apart from the Observatory staff, around 80 volunteers from "Friends of the Observatory" offered support and assistance as goodwill ambassadors in warmly greeting the visitors.
