The Hong Kong Observatory (HKO), a department of the Hong Kong Government, is responsible for monitoring and forecasting weather, as well as issuing warnings on weather-related hazards. Founded in 1883, it has a long and distinguished history of serving the community with timely and accurate meteorological information. From humble beginnings focused on timekeeping and basic weather observations, the HKO has evolved into a modern, technologically advanced institution playing a crucial role in safeguarding the lives and property of Hong Kong residents.
One of the HKO’s primary functions is weather forecasting. Its meteorologists analyze data from a variety of sources, including surface observations, weather balloons, radar, and satellite imagery. Using sophisticated computer models, they generate forecasts ranging from short-term predictions of localized weather phenomena to longer-range outlooks covering several days. These forecasts are disseminated through various channels, including the HKO’s website, mobile app, television, radio, and social media, ensuring that the public has access to the latest weather information.
Given Hong Kong’s vulnerability to typhoons, the HKO plays a vital role in issuing typhoon warnings. A comprehensive warning system, consisting of numbered signals, alerts the public to the potential threat posed by tropical cyclones. These signals range from Standby Signal No. 1, indicating a distant typhoon, to Hurricane Signal No. 10, warning of imminent or actual hurricane-force winds. The HKO’s careful monitoring and timely warnings allow businesses and individuals to take necessary precautions, minimizing the impact of these powerful storms.
Beyond typhoons, the HKO also issues warnings for other weather-related hazards, such as rainstorms, thunderstorms, and heat waves. The rainstorm warning system, categorized as Amber, Red, and Black, alerts the public to the risk of flooding and landslides due to heavy rainfall. Similarly, warnings are issued for extreme heat conditions, advising people to take steps to avoid heatstroke and other heat-related illnesses. These warnings are crucial in mitigating the risks associated with severe weather events.
In addition to its operational duties, the HKO also conducts research and development to improve its forecasting capabilities and understanding of weather phenomena. It collaborates with other meteorological organizations and research institutions around the world, contributing to the advancement of weather science. The HKO also actively promotes public education on weather and climate change, raising awareness of the importance of preparedness and adaptation.
The Hong Kong Observatory is more than just a weather forecasting agency; it’s a vital institution that safeguards the well-being of Hong Kong’s community. Its dedication to accuracy, innovation, and public service makes it an indispensable part of the city’s infrastructure, ensuring that residents are well-informed and prepared for whatever the weather may bring.
