Uses of weather balloon are according to size and material. Mainly include below types:
(1) Anemometer balloon
Named small balloon in meteorology, made of rubber, shell weight approach 30g, mainly use for theodolite anemometric or border stratum sounding, highest rising height can be 10~15 km.
(2) Sounding balloon
Made of natural rubber or neoprene synthetic rubber, shell weight 0.8~2.0kg, speed can be 5~6m/s if carry a 1kg device, highest rising height can arrival 30km, is the most regular balloon for daily height sounding.
(3) Captive balloon
Use cable tie on the winch on the ground, can control the height of rising. Usually made of polyester film and form streamline, cable length and the angle of intersection between cable and ground can calculate distance of captive balloon from ground, it can carry measurement device continuous measuring hours in specify height sky. Captive balloon is recycling balloon, suit for air pollution monitoring and air border stratum research.
(4) Constant-level balloon
Drift stable in the air of equidensity stratum, also named equidensity balloon or constant volume balloon. Balloon made of multilayer composite membrane of plastic, good resistance to pressure and good gas keeping. Inflate air partial into balloon on the ground when release, rise to expected height, because gas volume in the balloon does not change so the density does not change, it keep drifting in equidensity stratum, balloon size is according to drifting height and carrying device weight, diameter arrange from 1 to 10 meters, drift in the air few days or months. Big constant-level balloon diameter can be 22 meter, arrival height can be 24km, can carry 200 pieces radiosonde.
