The Hong Kong Observatory December 15 commemorated the 50th anniversary of weather radar observations in Hong Kong. A new weather radar product featuring radar images on geographical information display was launched to enhance weather radar services for the public.
At a press conference, Assistant Director of the Hong Kong Observatory, Mr Shun Chi-ming, reviewed the history of weather radar observations in Hong Kong. He said weather radar had been serving Hong Kong since 1959.
Installed at Tate's Cairn, the first weather radar enabled the tracking of typhoons. The eye of Typhoon Wanda in 1962 could be clearly depicted on the radar image. With the subsequent introduction of digital weather radar, Doppler weather radar and windshear-detecting terminal weather radar, not only did the Observatory enhance its capability in weather detection, but more user-friendly radar products became available to weather forecasters, specialised users and the public.
The present weather radars provide many products and are indispensable to weather forecasters. To make the weather radar images more user-friendly, the Observatory today launched on its website a new radar product based on a geographical information platform. People can interactively zoom in and out of the radar images, and make reference to a host of geographical information such as roads, public utilities and well known places, to enable them to know more precisely locations affected by rain. The new radar products are accessible on:
