Extended Abstract

southern hemisphere through the equatorial region of Southeast Asia . Number of vertical is 26, inwhich pressure on the colleges is 10 mb. Step time integrals are set to 60 seconds.2.2 Create initial seed and breeding approachIn this process of initially cr eating Ti me-Lagged ap proach, t he conten ts o f this method are asfollows: Using data analyzed by the OBS 48,42,36,30 hours before the time of making predictionsand integrate the RAMS model to 24 hours before predicted. Select each corresponding pair of afield and subtract to create a perturbation field (D1, D2, ..., D6). We finally normalize the resultedperturbation field associated with each pair to the original noise (Figure 1a).Results of how to create noise is the noise created originally for each of six fields (te mperatureand wind components). The noise will be adopted to find the fastest growing mode.The breeding method based on the idea of two authors Toth and Kalnay (BGM) [2]. The contentsof this method as follows:a / Create any noise and standardized as described aboveb / Add and subtract noise has standardized with analysis field and integral model 6 hours withinitial boundary condition is used to update the NCEP.c / The two fields took effect predicted for the new noise D at the time t +6d / Standardization of this interference by the formulaD* = S.DWhereS C / PPT p 850N T1p850NTn8502N is the number of grid points,nT: is the value of a p air of positive and n egative predictions of the850temperature field in the 850mb, C is a coefficient (chosen by experience).In theworke it was chosen C = 1.2e/ Repeat from step b/ service at T00 (Figure 1b) we find the noise development}D1}D2}D3}D4}D5}D6T(-48) T(-42) T(-36) T(-30) T(-24)AFigure 1: Create initial seed and BGM approachb2.3 Initial dataUsing global GFS data with a resolution of 1x1 degrees Theodolite interpolation of grid computerupdates the weather station data and sea surface temperatures average week NCEP3.
