Wavelet software was provided by C. Torrence and G. P. Compo and is available online (http://paos.colorado.edu/research/wavelets/).
Analysis was performed in NCAR Command Language (NCL) and scripts were modified from functions included in NCL. The authors thank the entire NCL team, especially Mary Haley and Dennis Shea. T-REX data were collected with the help of the NCAR flight facility staff and the whole T-REX staff. This research was supported by a grant to Yale University from the National Science Foundation (ATM-112354).
