Radiosonde

Definition

A radiosonde is a battery-powered, telemetry instrument that is carried into the atmosphere by a weather balloon to collect data on temperature, humidity, pressure, and wind speed at various altitudes. These instruments play a crucial role in understanding the characteristics of different atmospheric layers, as they provide real-time data that helps meteorologists analyze weather patterns and atmospheric conditions.

5 Must Know Facts For Your Next Test

1. Radiosondes are typically launched twice a day from various locations worldwide, contributing to global weather observation and forecasting.
2. The data collected by radiosondes is essential for creating weather models that predict atmospheric behavior and severe weather events.
3. Radiosondes can reach altitudes of over 30 kilometers (about 18.6 miles) before the balloon bursts and the instrument falls back to Earth.
4. These instruments transmit data back to ground stations in real-time, allowing meteorologists to monitor changes in the atmosphere as they occur.
5. Radiosonde measurements are crucial for studying phenomena like temperature inversions and identifying layers of stability or instability in the atmosphere.
