HKO seeks HK$55m for new radar system
The Hong Kong Observatory (HKO) is hoping to set up a new radar system to better monitor and predict severe weather across the city. The "phased array weather radar system" would provide detailed weather images that update quickly, helping to detect fast-changing weather conditions. The Environment and Ecology Bureau is seeking funding approval from Legco for HK$55 million to buy three sets of the radars. At a Legco panel meeting on Monday, Environment Secretary Tse Chin-wan said the system would benefit the development of a low-altitude economy. "Weather of course is important when it comes to low-altitude flying. This radar system could detect weather changes up to a few hundred metres above ground, So the weather radar system will help to enhance the safety of low-altitude vehicles and devices," he said. Together with an existing one in Sha Lo Wan, the proposed new radars in Cheung Chau, Lau Fau Shan and Tung Lung Chau would cover the whole territory. Asked how to monitor "ionospheric scintillation" which affects drones, HKO's assistant director Chan Sai-tick said the observatory is using space weather data from the mainland and other countries and looking for ways to track ionosphere changes. Chan added that the new radars offer higher resolution and faster updates, allowing more accurate predictions of severe weather such as hail and tornadoes.
