Usually, an optimal time window (OTW) centred at the assimilation time to collect measured
data for an assimilation cycle, can greatly improve the CDA analysis skill. Here, with a simple coupled
model, we study the impact
of optimal OTWs on the quality of parameter optimization and climate
prediction. Results show that the optimal OTWs of valid atmosphere or ocean observations exist for the
parameter being estimated and incorporating the parameter optimization will do some
impact on the
optimal OTWs for the state estimation. And using the optimal OTWs can enhance the predictability
both of the atmosphere and ocean.
