Short summary
We developed a new method to detect turbulence in the atmosphere using global high-resolution balloon measurements of temperature and wind. Unlike earlier methods, ours can detect turbulence not only in unstable air but also in stable layers with strong wind changes. This approach better matches aircraft turbulence reports and reveals global patterns, such as seasonal shifts linked to jet streams and convection, helping improve flight safety and our understanding of extreme weather.
