However, winds are usually measured by tracking the balloon..

The tracking mentioned by Bob Pursley can be done with the GPS system or with radar.

The instrument carried by a weather balloon to measure upper-level pressure, temperature, humidity, and winds is called a radiosonde. Radiosondes are typically small, lightweight devices that are attached to weather balloons and are used to collect data about the atmosphere as they ascend through the atmosphere.

To find the name of the instrument carried by a weather balloon, you can follow these steps:

1. Start by understanding the purpose of the weather balloon. Weather balloons are launched to gather data about the atmosphere at different heights, providing insights into weather conditions, atmospheric stability, and other meteorological phenomena.

2. Identify the types of measurements that need to be taken. In this case, the question mentions pressure, temperature, humidity, and winds at upper levels. These measurements are crucial for understanding the atmosphere's structure and dynamics.

3. Research the equipment used for such measurements. The instrument that fulfills these requirements is a radiosonde.

4. Verify the information by consulting reliable sources such as meteorological organizations, scientific journals, or encyclopedias.

By understanding the purpose of a weather balloon and the type of atmospheric data that needs to be collected, you can determine that a radiosonde is the instrument used for measuring upper-level pressure, temperature, humidity, and winds.
