What eventually happens to all weather balloons as they rise through the atmosphere?
As the balloon rises, the gas inside the balloon expands because the atmospheric pressure surrounding the balloon drops. The atmosphere is 100 to 200 times less dense at the float altitudes than on the ground.
Do weather balloons leave the atmosphere?
The weather balloon will carry a parachute as well as a payload or a box with the sensors to detect items such as temperature, pressure, humidity and GPS. It will rise through the atmosphere, and after leaving the tropopause it will enter the stratosphere.
Do weather balloons get smaller as they rise?
Weather balloons get larger as they rise through the atmosphere to regions of lower pressure because the volume of the gas has increased; that is, the atmospheric gas exerts less pressure on the surface of the balloon, so the interior gas expands until the internal and external pressures are equal.
Are weather balloons biodegradable?
Although latex balloons are considered bio-degradable, this will take anywhere from 6 months to 4 years to decompose and they can wreak a lot of havoc before they do.
What happens to balloons when they are released into the sky?
One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. If you inflate a balloon beyond its limits at room temperature, it will break into small pieces up to about ten centimetres long.
Where do weather balloons collect data?
These data are obtained from radiosondes, which are instrument packages tethered to balloons that are launched from the ground, ascend through the troposphere into the stratosphere, and transmit back to a receiving station on the ground.
