[Photo/Xinhua] BEIJING - China has successfully designed and tested its first drone-carried dropsonde, or meteorological data monitor, to carry out meteorological observations. The unmanned aircraft vehicle (UAV) will carry the dropsonde and drop it at an altitude of 6,000 meters to measure atmospheric profiles as the device falls to the ground. Launched using a parachute, the dropsonde can descend at a stabilized speed and cut the atmosphere column like a scalpel to gather data such as temperature, humidity, and wind direction and transmit them to ground receiving devices in real time. The dropsonde carried by UAV was produced by the Second Institute of China Aerospace Science and Industry Corporation Limited (CASIC) and the test was run and monitored by the Meteorological Sounding Center of China Meteorological Administration (CMA) in May. The drone-carried dropsonde is an essential payload for aircraft meteorological sounding, which is more targeted than weather balloons and applied in much wider fields than rocketsonde, said Zhang Xuefen, a researcher at the CMA. Such dropsondes are small and light and have a high accuracy when applied. Once equipped with a power cord and data wire, these dropsondes can be hung from any part of a drone's wing, belly or cabin and work stably and reliably between 70 degrees Celsius and minus 90 degrees Celsius. According to the CASIC, drone-carried dropsondes can be widely used in meteorological emergency, disaster and ecological monitoring and offer a convenient and low-cost option for artificial meteorological observation and response systems in the future. 24-hour-wristbandsfigured-wristbandprinted-wristbanddebossed-wristbandcustom-bracelets
HONG KONG - A ceremony was held here Saturday to mark the founding of Hong Kong STEM (science, technology, engineering, mathematics) Education Alliance, which aims to foster the development of STEM education and innovation and technology (I&T) in Hong Kong.Chief Executive of China's Hong Kong Special Administrative Region (SAR) Carrie Lam, Director of the Liaison Office of the Central People's Government in the Hong Kong SAR Wang Zhimin and some other guests officiated at the ceremony.Through liaising with people who support, promote and lead the development of STEM education in Hong Kong, the alliance aims to enhance students' interest in science and technology and strengthen students' necessary knowledge.Speaking at the ceremony, Lam said that the Hong Kong SAR government puts a lot of emphasis on nurturing innovation and technology talent. In her latest policy address, she proposed to provide, starting from the 2019/20 school year, a new recurrent Life-wide Learning Grant with an annual provision of 900 million HK dollars (about $115 million).Lam said the grant will support schools to take forward, on the present foundation, life-wide learning with enhanced efforts through organizing more out-of-classroom experiential learning activities in various curriculum areas such as STEM education, so as to broaden students' horizons and foster their overall development.Tsui Lap-chee, president of the alliance said that for the purpose of Hong Kong becoming an international innovation and technology center, the alliance will train a huge number of scientific and technological talents with creativity and comprehensive, collaborative and problem-solving skills.The alliance will also promote STEM activities and organize STEM competition to support STEM education in Hong Kong.The 1st Hong Kong STEM Education Forum was also held by the alliance on Saturday, with the attendance of more than 700 experts, teachers and students.
