Short summary
Different kinds of waves are the subject of intense research because they are suspected to steer several different atmospheric phenomena. To analyse the effects of waves, wave packet characteristics have to be known. We introduce a new tool to study wave packets locally: Unified Wave Diagnostics (UWaDi). To show the advantages of UWaDi, a sudden stratospheric warming period in 2016 is analysed for different background wind conditions, revealing gravity waves emitted from a jet exit region.
