the balloons have satellite tracking device inside which sends signalls to a satellite. The balloon moves through the air in certain places because of the weather, and these movements are tracked by the satellite. the meteoroligists know what these movements means, and can determine almost exactly what is happening: wind currents etc.
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.
High resolution satellites (e.g. those operated by commercial satellite companies like GeoEye or DigitalGlobe) are used to take pictures of Earth. A lot of the imagery comes from aerial photographers mostly in airplanes with special high resolution cameras. Some of the imagery even comes from kites and balloons.
The Meteorological balloons manufactured from natural rubber latex by our factory are used to detect air basic factors in natural environment. It has two types, one is wind-cloud-detecting Meteorological balloon and the other is sounding balloon. It acts as carrying tools used widely in Meteorological detecting. It is one important and necessary tool to develop Meteorological science, aviation, interspace technology. The Meteorological balloon follows GJB1961-94 standard issued by The Military Standard of P.R.C. in quality, specification, packing.
Once the balloon gets high enough in the atmosphere, the ambient atmospheric pressure becomes very low (say 20mb = 2000Pa). There is a pressure gradient force from the high pressure of the air inside the balloon to the air in the environment outside of the balloon, working across the balloon material. Once this PGF becomes stronger than the tension of the balloon material, the balloon will pop.
We don't have "daliy" weather in this country... come back to Amerika when you learn to spell.
Weather balloons typically stay aloft in the atmosphere for about 12 to 24 hours before they burst and fall back to the ground.
there is a rope, much like the rope truckers pull for their horns, that you pull down, opening a flap on the top,letting the warm air out. this allows them to float back to earth...
Weather balloons collect data about the weather by carrying instruments called radiosondes high up into the atmosphere. These instruments measure temperature, humidity, and air pressure as the balloon ascends. The data is transmitted back to the ground, where it is used to create weather forecasts and study atmospheric conditions.
A common instrument that gathers information and sends it back to Earth is a satellite. Satellites can collect various types of data, including images, weather information, and scientific measurements, and transmit this data to ground stations for analysis. They are essential for communication, navigation, and Earth observation. Examples include weather satellites and Earth observation satellites like Landsat.
A weather balloon is something that people who study weather send up into the air to learn more about weather and find weather patterns.
Escaped balloons can only rise to the altitude where they are the same density as the surrounding air; they cannot go into space. Eventually the helium leaks out and they fall back down.
Balloons that fly away typically end up in the atmosphere where they can eventually deflate and fall back to Earth. This can have harmful effects on wildlife and the environment as the deflated balloons often end up as litter. It is important to properly dispose of balloons to prevent this from happening.
Weather balloons work by carrying instruments called radiosondes that measure various atmospheric parameters such as temperature, humidity, and pressure as they ascend through the atmosphere. The balloons are filled with helium or hydrogen gas, which causes them to rise and reach high altitudes where the data can be collected and transmitted back to the ground station.
By releasing some of the hot air in a very controlled manner.
What they do is blast cold air into the "hot" air and it makes the air molecules slow down... Thus it makes the air balloon decrease back to earth.
A Weather Balloon is attached to an instrument called a Radiosonde. The radiosonde is a a box with smaller instruments to measure the temperature, dew point, wind speed, and wind direction, among other things, at different levels of the atmosphere. The balloon pretty much is there to lift the Radiosonde through the atmosphere.
Satellites take pictures and accumulate other information into the computer. They analyze the data and send it back to weather stations on earth.
