Question

which is one function of a weather balloon? enables forecasts seven to 10 days in advance measures conditions in the upper atmosphere locates and tracks storms and follows the path of storm systems uses mathematical equations to show what will happen if conditions change

Explanation:

Weather balloons carry instruments aloft to gather data like temperature, pressure, and humidity in parts of the atmosphere that are not easily reached by ground-based tools. Long-range 7-10 day forecasts rely on complex models and multiple data sources, not just weather balloons. Storm tracking is typically done by radar or satellite, and mathematical scenario modeling is done by computer weather models, not the balloons themselves.

Answer:

measures conditions in the upper atmosphere
