| Abstract: | In this study, singular vectors related to a heavy rainfall case over the Korean Peninsula were calculated using the fifth-generation
Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) adjoint modeling system. Tangent
linear and adjoint models include moist physical processes, and a moist basic state and a moist total energy norm were used
for the singular-vector calculations. The characteristics and nonlinear growth of the first singular vector were analyzed,
focusing on the relationship between the basic state and the singular vector. |
