  1. The current status • Build the xml and ksh scripts for ENKF and GSI(40km) • 40 members was divided to 8 groups. GSI: 5~10 minutes/group ENKF: <5 minutes WRF(3hours forecast): 5~10 minutes/group

  2. What I have tested---GSI analysis only? • Configuration in WRF using the 3.1 and 3.2 3.1 damp_opt = 3, dampcoef = 0.05 moist_adv_dfi_opt = 0 Vs 3.2 ishallow = 1, cu_rad_feedback = .true., prec_acc_dt = 60. damp_opt = 1, dampcoef = 0.02 moist_adv_dfi_opt = 2

  3. What I have tested---ENKF analysis using the WRF3.2 confiuration? • Configuration in ENKF Correlation length corrlengthnh = 1000 .or. 600 corrlengthtr = 1000 .or. 600 corrlengthsh = 1000 .or. 600 Time windows obtimelnh = 10.0 .or 6.0 obtimeltr = 10.0 .or 6.0 obtimelsh = 10.0 .or 6.0 Inflation coefficient analpertwt = 0.5 .or. 0.2 covinflatenh = 0.2 .or. 0.1 covinflatetr = 0.2 .or. 0.1 covinflatesh = 0.2 .or. 0.1 Observation Qc sprd_tol = 9.9e31 .or. 1.0 Inflation limit covinflatemax = 1.e30 .or. 1.5

  10. Add constraint in the ‘get_convobs_data’ • Temperature: If abs(Hx-O) > 5.0 Set x_qc(nob) = -999 • U and V: If abs(Hx-O) > 20.0 Set x_qc(nob) = -999 • Surface pressure: If abs(Hx-O) > 5.0 Set x_qc(nob) = -999 • Qvapor: If abs(Hx-O) > 2.0 Set x_qc(nob) = -999
