JS+Weather+Balloons

Ever since World War 2 meteorologists have used weather balloons to provide information such as temperature, pressure, relative humidity, and wind velocity. There are more that 700 launching spots all over the world. At these spots they launch all of the balloons at the same time. All the data is sent to the United States through a central computer. The balloons are inflated with either helium or hydrogen to a diameter of 2 meters. Devices put into the balloons gather the data as it is in the air. The instrument packages transmit barometric, relative humidity, and termperature datat to the ground by radio transmission. It sends the data in different rotations, such as temperature first, next humidity, and so on.


 * __Questions:__**


 * 1) The technology we have didn't let the weather satellites interfere with the readings and data that the weather balloons collected.
 * 2) If they didn't understand the gas laws, then we wouldn't be able to understand why the balloons go up with the heat and gases and the pressure goes down.
