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

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?
