Introduction
The method to compute the wave packet envelope can be found in section 2c of Chang and Yu (1999): “Characteristics of wave packets in the upper troposphere. Part I: Northern Hemisphere Winter”. J. Atmos. Sci., 56, 1708-1728. For an introduction about what wave packets are and the applications of wave packet diagnostics, click here.
