1. Stratiform vs Convective

3. Ref+Vel
stratiform
Conv(all)+ rad_ref
Cloud analysis followed by 3dvar
Conv(uv+spd)+rw
Only 3dvar analysis
Applied DFI to Qv only, other mosit variable like Qs, Qc, Qr, Qg, Qi are remain unchanged and
Temperature tendency added gradually (Current RUC version)
CV(Ref+Vel)
convective
The same above
Cld_qv
Qcw and Qci use Convective method and Qv using the stratiform or convective method, and all of these based on the classification.
Cldall
all using the stratiform or convective method based on the classification.

4. Qn (Convective) – Qn (Stratiform) 700hPa

5. Qn (Convective) – Qn (Stratiform) 500hPa

6. Qcw (Convective) – Qcw (Stratiform)
tmc (Convective) – tmc (Stratiform)

7. Classify methods Steiner et al. 1995 (1). RefZ3km>40dbz
(2). RefZ3km-Zbg > 10 – Z2bg /180
here, Zbg is average of Ref at 3 km height 11 km around the computer grid.
(3)any grid point identified as a convective center by one of above two criteria, all surrounding grid points within an intensity-dependent convective radius around that grid point are also included as convective area
But considering the grid resolution of RR is 13 km , we only applied the rule (1) and (2).
