Weather Things: Weather Balloons

Meteorologists require data from various atmospheric levels to understand weather. Weather balloons, launched globally twice a day, collect this data. These balloons carry instruments that transmit real-time data back to Earth, creating a vertical profile of weather parameters. Balloons can reach up to 20 miles high before bursting, and their instruments often land unrecovered. However, recovered instruments can be reused. Despite being old technology, weather balloons provide essential data.

Describe the process of how a weather balloon ascends and transmits data.
