Since the 1930s, the National Weather Service in Chanhassen, United States, has been utilizing weather balloons filled with hydrogen gas to study changes in the upper atmosphere up to 20 miles above the ground. Meteorologist Joe Strus explained that this method provides a 3D picture of the atmosphere, capturing real-time changes in temperature, pressure, humidity, and wind speed with the help of radiosondes. These instruments are attached to the weather balloons and ascend into the atmosphere, collecting data that is vital for meteorologists across the country for daily weather forecasting and special events such as tropical systems. The evolution of monitoring atmospheric variations has progressed from using kites and hot air balloons in the 1700s to the current innovative approach of launching weather balloons twice daily, providing valuable insights for weather predictions. The collaborative effort of weather balloon launches not only enhances forecasting accuracy but also supports meteorologists in different regions, showcasing the continuous advancements in meteorological technology and research.
