Data for simulations created with CM1 Version 19 for the journal article "On the Dynamics of Atmospheric Bores" By Dr. Kevin Haghi and Dr. Dale Durran. The numerical model is publicly available at https://github.com/NCAR/CM1 We used CM1 Numerical Model, Release 19.3 (cm1r19.3) 25 August 2017 The basic numerical parameters for the simulations are given in the manuscript. Here we provide data to allow the reproduction of these relatively inexpensive idealized simulations and Matlab codes for the single case where a complex initial condition is imposed (a trapped wave packet). **** High resolution input soundings for each type of simulation are in folder Soundings *** Here they are index by figure number 1) Figure 3 Trapped_wave_same_environment_no_coldpool_310 3) Figure 7a,b; Figure 10a,b: compositejet_compositetheta 4) Figure 7c,d: 10msconst_compositetheta 5) Figure 7e,f; Figure 10c,d: idealjet_idealtheta 6) Figure 7g,h: 10msconst_idealtheta 7) Figure 7i,j: idealjet_compositetheta *** Folders for Matlab programs *** Matlab_TrappedWave_Sover: Folder with Matlab code for solving the eigenfunction-eigenvalue problem for resonant modes Matlab_Initialization: Folder with Matlab code for initializing the trapped wave packet
