WEATHER BALLOONS carry an instrument called "Radio-sonde" which measures temperature, pressure, and humidity at different altitudes in the atmosphere. Special recording equipment in the balloons converts readings from these instruments into electrical impulses and transmits the impulses to earth. The balloons are tracked with radar to find wind speed and direction. Eventually the balloon bursts, and the instrument floats back to the ground by parachute.
