  • 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


What i have tested gsi analysis only
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


What i have tested enkf analysis using the wrf3 2 confiuration
What I have tested---ENKF analysis using the WRF3.2 confiuration?
