Some potential synonyms for "weather balloon" include reconnaissance balloon, meteorological balloon, atmosphere probe, and stratospheric balloon. These terms all refer to a type of balloon used to gather information about the weather and atmospheric conditions. Weather balloons are typically made of latex or synthetic materials and often carry instruments such as radiosondes, which transmit data on temperature, pressure, humidity, and wind velocity. They are used by meteorologists and other scientists to monitor weather patterns, forecast storms, and track atmospheric changes over time. While the term "weather balloon" is perhaps the most commonly used, there are a variety of other terms that can be used to describe this important scientific tool.
