Scientists are developing unmanned planes -- called drones -- that can gather weather information from the atmosphere. The drones could help weather experts improve their predictions. Meteorologists say their weather forecasts would be more accurate if they had information from many parts of the atmosphere. They already place satellites, drones and balloons at different altitudes. And they use radar and gather information from devices on towers. But that information only helps experts predict weather conditions for the next few days. It does not help predict changes in the next few hours. This is very important where sudden, violent storms happen. So scientists at Oklahoma State University are developing new drones to gather information from more parts of the Earth’s atmosphere. This will help forecasters improve predictions about local weather conditions.
