A tropical channel model was constructed to study the long-standing
problem of the initiation of the Madden-Julian Oscillation (MJO).
Two MJO cases were studied through numerous sensitivity tests.
These tests demonstrated that the simulated MJO initiation was
critically dependent on the time dependent lateral boundary
conditions from the reanalysis. The mechanisms of extratropical
influences were further explored, which showed the importance of
momentum transport at the lower troposphere and wave activities at
the upper troposphere. The dynamics of the MJO and its dependence
on the mean state were also studied using multi-year simulation of
a nested regional climate model. In short, this study has shown
that the extratropical influences can be an efficient mechanism for
the MJO initiation and calls for further research attention to this
mechanism that has been somewhat neglected by mainstream MJO
research. This work should be useful to researchers in tropical
dynamics and thermodynamics and numerical modeling. It would also
be helpful to students who are studying Meteorology, Atmospheric
Sciences, or Physical Oceanography.
