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.

Why is it important for meteorologists to understand weather parameters at different altitudes?

• To track animal migration

• To understand global weather patterns

• To predict local weather conditions only

• To measure sea level changes

What is the primary purpose of launching weather balloons?

• To measure ocean temperatures

• To provide internet connectivity

• To collect upper air weather data

• To monitor wildlife

What technology do newer radiosondes use to enhance data collection?

• Bluetooth

• Infrared

• GPS

• Wi-Fi

What happens to a weather balloon at high altitudes?

• It remains intact indefinitely

• It bursts due to low pressure

• It deflates and falls

• It changes color

What is done with radiosondes that are recovered?

• They are displayed in museums

• They are sold to private companies

• They are refurbished and reused

• They are discarded
