Historical Evolution of Hong Kong Weather Information Center

1883 the hong kong observatory was established.

1884 Start routine meteorological observation. Establish a tropical cyclone warning system (the earliest marine meteorological service in Hong Kong). The Observatory has set up a drum-shaped and cone-shaped tropical cyclone warning system to inform departing ships of the location and moving direction of typhoons. This system was replaced by ten tropical cyclone warning signals in 19 17. This system was abolished on June 196 1.

Tsim Sha Tsui Police Department lowered the 1885 time ball for the first time.

1892 started to provide meteorological services in the harbour. The Observatory sends the 24-hour weather forecast to the newspaper every day so that it can be published outside the newspaper number published around noon.

1908 receiving ship weather report by wireless telegraph. The New Times Tower in signal hill, Tsim Sha Tsui (also known as Dabaomi or Blackhead Corner) will replace the Times Tower in Tsim Sha Tsui Marine Police Headquarters. Later, because the radio broadcast time signal has been widely used, the time ball was dismantled on June 30th, 1933.

19 15 began to provide wireless broadcast of ship weather forecast.

19 17 A visual tropical cyclone warning system representing local wind power was put into use in July, replacing the local typhoon gun (sound) storm signal used since 1884. This visual system is the origin of tropical cyclone warning system at present.

192 1 Use balloons for high-altitude exploration. Start seismic survey.

The weather forecast of 1928 is broadcast on Radio Television Hong Kong.

1937 set up aviation meteorological service.

1948 Joined the International Meteorological Organization (﹝IMO﹞), the predecessor of the World Meteorological Organization (﹝WMO﹞).

1949 using radiosonde and radar sounding system to measure high-altitude meteorological data.

The first weather radar was set up at 1959 observatory.

196 1 Start measuring radioactivity in the atmosphere.

1964 receives the automatic image transmission signal (﹝APT﹞) of polar-orbiting satellites.

1966 started broadcasting the observatory's 6-ring time signal directly on 1966 at a frequency of 95 MHz, and stopped running on 1989 on September 6. To this day, Radio Television Hong Kong (RTHK) continues to broadcast the 6-ring time signal from the Observatory.

1967 began to issue thunderstorm and rainstorm warning.

1973 the observatory established the first computer system.

1975 The Observatory exchanged meteorological data through the Global Telecommunication System (﹝GTS﹞) of the World Meteorological Organization, and established the following three sets of regional dedicated circuits: Hong Kong-Tokyo (1969) Hong Kong-Bangkok (1970).

1977 receives the low-resolution satellite image of geostationary meteorological satellite (﹝GMS﹞) of Japan Meteorological Agency. Began to issue landslide warning.

1979 A short-period seismic network consisting of three stations was established. The Observatory's first numerical model of weather forecast (balanced barotropic model) has been put into operation. Receive the high-resolution satellite image of geostationary meteorological satellite (﹝GMS﹞) of Japan Meteorological Agency. The Observatory installed five anemometers at the runways of Kowloon City and Kai Tak International Airport to test the wind shear at the airports. 1980 established the first cesium atomic clock time system.

1983 provides three-day weather forecast service.

1984 The first two automatic weather stations providing public weather services were set up at the Observatory headquarters and Sha Tin respectively, while another automatic weather station providing aviation weather services was put into operation at Chek Lap Kok. The observatory's real-time rainfall data collection system began to operate.

1985 The first automatic weather station in Guangdong and Hong Kong started operation in Huangmaozhou. Set up a telephone meteorological service and a radiation measurement room in kings park.

Establish an environmental radiation monitoring plan. The scientific officer of the Observatory began to host TV weather programs.

1988 a new numerical model of weather forecast (limited area numerical model) has been put into operation, which is mainly aimed at small-scale weather systems affecting Hong Kong and its adjacent areas. The Observatory transmitted the weather information and forecasts of 23 world cities to the Information Service of Hong Kong and Radio Television Hong Kong for distribution to the media and the public.

1990 radiation monitoring and evaluation center was established.

1992 A color-coded "rainstorm warning system" came into operation.

1993 the observatory began to measure ozone and radiation at high altitude.

1994 the observatory's first Doppler weather radar began to operate.

1996 the observatory has set up a webpage on the internet. Establish Friends of the Observatory, strengthen communication between the public and the Observatory, and raise public awareness of meteorological services.

1997 expand the seismic network to 8 stations and transmit it with digital signals.

1998 provides interactive information inquiry system (﹝IES﹞) service. The Airport Doppler Weather Radar (﹝TDWR﹞) of the Observatory began to operate, detecting windshear and turbulence every minute and issuing relevant warnings to aircraft. Launch a four-day weather forecast service. 1In July 1998, the aviation meteorological service was moved from the old Kai Tak Airport to Chek Lap Kok. The new Hong Kong International Airport at the Cape.

1999 The new weather radar system installed by the Observatory at Tai Mo Shan was officially opened. The new system provides high-resolution radar data, which can monitor bad weather more effectively. A supercomputer has been added to the Observatory to run a high-resolution numerical model of weather forecast (service area spectrum model) to enhance the ability of forecasting rainstorm. Start issuing cold weather warning. Start providing ultraviolet index.

In 2000, a resource center was opened in the commercial building near the Observatory to facilitate public access to information and publications. The Observatory added an efficient server cluster to improve its meteorological data processing ability. Launch a five-day weather forecast service. Early warning of high temperature weather was issued.

200 1 The Observatory strengthened its website service by providing text version and audio webpage to facilitate visually impaired people to obtain weather information.

In 2002, the "World Weather Information Service" website sponsored by the World Meteorological Organization and developed and managed by the Hong Kong Observatory was officially put into operation. This is the first time in 2003 that the automatic weather report was successfully received from a computer on a commercial plane.

In 2004, the first automatic high-altitude detection system in Southeast Asia was officially put into use.

In 2005, the Observatory cooperated with Guangdong Meteorological Bureau and Macau Geophysical and Meteorological Bureau to establish lightning location network and launch lightning location information service.

In 2006, the Observatory launched an ultraviolet index forecast service to facilitate the public to consider appropriate sun protection measures. The Observatory installed a second lidar system at the Hong Kong International Airport to enhance the windshear early warning service. In May 2006, the Hong Kong Observatory participated in the Pan-Pacific Tsunami Exercise for the first time since the establishment of the Pacific Tsunami Warning and Mitigation System for more than 40 years. Two real-time thermal stress measurement systems developed by the Observatory for the equestrian events of the 2008 Olympic Games were installed in the Hong Kong Sports Institute in Sha Tin and the Pisces River Equestrian Training School in Sheung Shui in June 2006. On February 26th, 2006, 65438, a strong earthquake occurred in Luzon Strait, which triggered a small tsunami. The Hong Kong Observatory released the first tsunami report in history. The Observatory changed the new domain names of worldweather and severe.worldweather for the website of the World Weather Information Service and Severe Weather Information Center managed by the World Meteorological Organization to show their international status. At the end of 2006, the Observatory successfully introduced the global-regional climate model to conduct climate prediction research. The quarterly climate forecast began to be released to the public.

In 2007, the number of wind stations near the reference sea level that issued tropical cyclone warning signals No.3 and No.8 increased to eight, covering the whole territory. In May, the director of the Observatory presided over some meetings of the General Assembly of the World Meteorological Organization, which was the highest-level meeting hosted by the staff of the Observatory at the World Meteorological Organization.

In 2008, the Observatory published the first regional temperature forecast in Hong Kong on its website.
