A global, six-level primitive equation model was numerically
integrated to examine the interaction of a planetary
wave
with a growing mid-latitude baroclinic wave. The
purpose of this study was to determine the contribution of
the baroclinic wave to the initiation of a monsoon surge.
Three experiments were run. Experiment I depicted the
effect of the planetary wave on the southward migration of
cold air. The cyclogenesis of a mid-latitude baroclinic
wave was shown in Experiment II. Experiment III combined
the growing baroclinic wave with the stable planetary wave
in an attempt to simulate a cold surge. Characteristics of
a monsoon surge were present in the numerical simulation but
not to the extent or detail of observed surges . The results
indicated the important role of planetary wave advections
in the formation of cold surges.
