机译：In this paper,an analogue correction method of errors (ACE) based on a complicated atmospheric model is further developed and applied to numerical weather prediction (NWP).The analysis shows that the ACE can effectively reduce model errors by combining the statistical analogue method with the dynamical model together in order that the information of plenty of historical data is utilized in the current complicated NWP model.Furthermore.in the ACE.the differences of the similarities between different historical analogues and the current initial state are considered as the weights for estimating model errors.The results of daily,decad and monthly prediction experiments On a complicated T63 atmospheric model show that the performance of the ACE by correcting model errors based on the estimation of the errors of 4 historical analogue predictions is not only better than that of the scheme of only introducing the correction of the errors of every single analogue prediction,but is also better than that of the T63 model.
