|Based on this model, we have
designed a kind of semi-multi-model ensemble prediction scheme. We perturb
the model coupling physics in three different ways. And for each model we use
three initial conditions generated by a simple nudging scheme assimilating
SST information only. This scheme works well for ENSO prediction because ENSO
is mainly determined by air-sea coupling.
But for the Indian Ocean prediction,
assimilating subsurface important can be very important because of
strong stochastic and influential intraseasonal disturbances there.
