Singular vectors and excess growths in semi‐implicit non‐hydrostatic models

In this note we show how the use of a semi‐implicit time discretization in a linearized non‐hydrostatic model can permit very large non‐modal perturbation energy growth. This occurs in a single normal‐length time step when a hydrostatically unbalanced increment at initial time is mapped to an approx...
