A weather balloon is a scientific instrument used by meteorologists to measure the activity of the world's weather. Weather balloons are sent into the air every day, all over the world; they are sent up at the same time, and they are used to measure a variety of atmospheric pressures, temperatures, and wind rates. The data collected by weather balloons is saved and transmitted by the radiosonde. Sensors in the radiosonde record data and use a radio transmitter to send the data back to the tracking station.
Weather balloons are inflated with either helium or hydrogen. Hydrogen is a more common substance many places use because it’s cheaper, but helium which is a low density gas, is also a very common substance. The weather balloons are made of latex or neoprene which is a synthetic rubber, because of the rubber thickness, it prevents unanticipated explosions. A normal weather balloon expands to an average of six feet in diameter before it’s launched into the air. As the balloon rises, it is capable of expanding to twenty two feet in diameter, which is the eruption point of weather balloons.
Two basic types of meteorological balloons: the smaller pilot and the larger balloons. The smaller balloons are usually tracked with a theologize; these balloons are not made to carry a payload. The larger balloons are specialized to carry a radiosonde in the air, and these balloons are commonly used by a rawinsonde tracking station. They can also carry other types of payload, such as radar targets.
The lifting capability of a helium balloon is connected to the volume of air displaced by the balloon; the larger the amount displaced, the greater the lift. If there was a balloon in a fixed temperature room, and the air temperature is 0 for instance the air would be denser and the balloon would rise faster than in a room filled with 100 degree air. If however, this was done outside and a current of hot air was rising, the balloon may move...
