High Altitude Balloon
Carry a radiosonde to the high altitude, for sounding temperature, pressure, humidity and wind. A high altitude balloon made of natural latex or neoprene synthetic rubber, with round, pyriform or other shapes. Weight of a high altitude balloon is about 200~2000g ( small ones rise to limited height will self-bursting ), inflate balloon with enough hydrogen or helium, can reach 98400 ft~ 131250 ft high altitude from ground surface, speed of regular weather balloon of high altitude meteorological station usually be 19.7 in~26.25 in/s, rising about 100000 ft will self-bursting. High altitude balloon is an important tool for stratosphere research, play an important role in meteorology development and weather forecast work.
