radiosonde
At the end of its flight, a weather balloon typically bursts due to the decreasing air pressure as it rises higher into the atmosphere. The instruments attached to the balloon then parachute back to the ground, where they are retrieved for data analysis.

As the balloon rises through the troposphere, the instrument will generally show a decrease in temperature and pressure with increasing altitude. The decrease in pressure will be more pronounced, leading to a drop in atmospheric density.
Weather ToolIt is called a radiosonde (or sonde for short) and is attached via a long string (and parachute for the descent) to a weather balloon that is filled with either hydrogen or helium. They are launched globally at least twice daily 00z and 12z (GMT). In the US, they can also be launched at other times in support of severe or other "high impact" weather events such as landfalling hurricanes, etc. AnswerA radiosonde flight is called a "sounding" and can done at other times as suggested above, if not one-off soundings for severe weather events, usually 06 and 18z. Most radiosondes give temperature, humidity and pressure data, other specialised high altitude sondes measure ozone (and since the sondes are so large, often have a smaller temperature sonde attached so the balloon flight is more useful). Some sondes also measure wind speed and direction via GPS (which doubles the cost of the sonde). Stations which have a windfinding radar use the simpler sondes with a radar target suspended under the balloon for wind data.Finnish Vaisala sondes have 60 metres of string on an unwinder attached to the sonde. This acts like a "sea anchor" while aloft, stabilising the balloon train in turbulent air, and which keeps the sonde away from the balloon after release both to protect the balloon from the sonde aerial and sensor array, and to ensure that the sonde is passing through air undisturbed by what can be a large spherical object- the balloon.
The pressure of the air inside it. The higher the balloon rises, the lower the outside air-pressure. With less pressure outside, the balloon expands because of the pressure of the air inside it. Eventually, the balloon bursts, and scientists recover the instruments when they fall to earth.
A 567kg weather balloon is designed to lift a 3670 package.......
A weather balloon unit is a package of equipment that typically includes a balloon, a radiosonde (instrument to measure various weather parameters), a parachute, and sometimes a radar reflector. This unit is used to collect weather data by releasing the balloon into the atmosphere, where it ascends and transmits information back to the ground station.
A radiosonde is an instrument package sent aloft attached to a balloon. A radar is a ground device which can track a balloon (with appropriate target attached) as well as pick up rainfall echoes (if it operates at the appropriate radio frequency)
A weather balloon carries weather instruments, such as a radiosonde, aloft to about 30,000 meters. As the balloon ascends, the instruments collect data on temperature, humidity, and pressure, transmitting the information back to the ground for weather forecasting and research.
At the end of its flight, a weather balloon typically bursts due to the decreasing air pressure as it rises higher into the atmosphere. The instruments attached to the balloon then parachute back to the ground, where they are retrieved for data analysis.
Radiosonde is the general term.
Weather balloons are typically white or light-colored, with a spherical shape when fully inflated. They are made of flexible materials like latex or synthetic rubber and have a small instrument package attached to measure and transmit data as the balloon ascends through the atmosphere. When they reach high altitudes, the balloons can expand to several meters in diameter before they burst and fall back to the ground.

Simply put, the weather balloon is a lighter-than-air vehicle or aerosonde that provides lift to an instrument package to get it to altitude. The instruments thus situated can collect data which, when combined with other information from both similar and different sources, can be used to assess current conditions, and, as an extension, to forecast weather.
A weather balloon gathers information on temperature, atmospheric pressure, humidity, and wind speed.
Sorry to say but none of you are really right, what you do is you send a big balloon up and the ailien that finds it takes a picture with the digital camera attached to the balloon and then they send it back down if you don't believe me even type into Google images ailiens capturing the weather! because i really ecconomicly should know that because i have had experience for i am a weather scientist.
