Measure the weather with balloons.

Why do you want to release white balloons when the typhoon strikes?

Before each typhoon comes, we can predict the typhoon in advance and take some safety measures to prevent it. Why can you know in advance? Thanks to the hard work of meteorologists, we know that when a typhoon comes, meteorologists will release white balloons for some reason. This white balloon is a probe balloon. Next, Bian Xiao will tell you why we should release the sounding balloon.

One of the most important meteorological observations is high-altitude meteorological observation, and the observation results affect many tasks such as weather forecast and climate analysis. The sounding balloon plays an important role in meteorological research, high-altitude meteorological observation and weather forecast analysis, and it is one of the important tools for us to study the atmosphere. The balloon itself cannot observe the data of high-altitude weather. The biggest function of balloon is to carry radiosonde into high altitude. Radiosonde has many electronic components, which can observe various meteorological elements, such as air pressure, temperature and humidity.

Meteorologists not only fly sounding balloons on typhoon days, but also fly sounding balloons at regular times. The sounding balloon is filled with hydrogen or helium, which is lighter than air, so it can rise to a height of 30 to 40 kilometers from the ground. Space balloons are not only round, but also pear-shaped and other shapes

After the balloon is released, it scans the temperature and humidity of the earth layer by layer like a stethoscope, thus helping us to obtain meteorological elements in the air. Although scientific and technological means such as meteorological satellites and sounding rockets have been applied in the field of space weather research, balloons are still indispensable tools for meteorological research. Compared with the above, it has the advantages of low cost, less investment, flexible launch time and being unaffected by regional climate factors.
