Background
Typhoon is a catastrophic weather system with strong destructive power, and the number of typhoons generated in the world is more than 60 per year on average, and 7.6 typhoons are generated when people land in China per year. Typhoon is a deep low-pressure system with very low central pressure, and the lower layer has significant gas flow converging toward the center, and the top gas flow diffuses outward. The typhoon has a complex structure and is divided into three areas from the center to the outside: typhoon eye area, cloud wall area and spiral rain area. The typhoon is accompanied with strong convection weather when crossing, and the harm is huge, therefore, each parameter of real time monitoring typhoon masters typhoon grade, scale, development condition and motion path, can evaluate the typhoon rationally, makes precaution work in advance, reduces the loss as far as possible.
The sonde is an instrument for measuring physical parameters of different heights of the atmosphere according to the vertical distribution rule of the physical parameters. The existing dropsonde generally adopts an air bag structure, helium is filled in the air bag structure, and the existing dropsonde is suitable for working in relatively stable weather.

In the existing drop-down sonde, a film of an air bag structure is made of polyethylene, the reliability of the sonde is generally enhanced by increasing the thickness of the polyethylene film, and even then, the existing drop-down sonde is not suitable for typhoon detection. Therefore, how to provide the dropsonde which is not easy to damage in typhoon has very important significance.
