What is the name of the white balloon released when the typhoon comes?

White balloons released by typhoons are called weather balloons.

Brief introduction of meteorological sounding balloon;

Meteorological balloon, also known as sounding balloon or meteorological balloon, is a tool for meteorological observation and data collection. They are usually large balloons filled with hydrogen or helium, which can carry instruments and sensors into the atmosphere to measure and record various parameters in the atmosphere. The following are some main features and uses of meteorological sounding balloons:

Structure of meteorological sounding balloon;

Meteorological balloons are usually made of thin film materials, such as rubber or plastic. Their outer layers are usually white to reflect sunlight and reduce daytime warming. Balloons are usually filled with hydrogen or helium to provide buoyancy. The balloon is attached with detection instruments, usually including thermometer, hygrometer, barometer, anemometer and altimeter.

The launching process of meteorological sounding balloon;

Meteorological balloons are released into the air after the ground is filled with hydrogen or helium. Because the gas in the balloon is lighter than the surrounding air, the balloon will rise into the atmosphere. During the launching process, the detection instrument records various parameters in the atmosphere.

Avoidance measures for typhoon weather:

First, pay attention to weather forecast and early warning:

Pay attention to the typhoon forecast and early warning issued by the meteorological department as soon as possible, understand the dynamic change, path and intensity of the typhoon, and make full preparations.

Second, do a good job in sorting out the living environment:

Fix outdoor items that are easily affected by wind disasters, such as flower pots and outdoor furniture. Clean up the sundries on the balcony and windowsill to prevent them from being blown off by the wind.

Third, prepare enough emergency supplies:

Prepare enough food, drinking water, medicines, emergency medical supplies, spare batteries, flashlights and other emergency materials to ensure adequate living security when the typhoon comes.

Fourth, strengthen housing security:

Check whether the windows, doors and windows of the house are firm to prevent damage caused by typhoon wind. Houses that are easily damaged by wind can be reinforced and fixed with adhesive tape. Before the typhoon comes, all doors and windows must be closed to avoid wind and rain.
