Stratiform vs Convective

Ref+Vel stratiform Conv(all)+ rad_ref Cloud analysis followed by 3 dvar Conv(uv+spd)+rw Only 3 dvar 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. The same above Cldall using the stratiform or The same convective method based on above the classification. The same above

Classify methods • Steiner et al. 1995 (1). Ref. Z 3 km>40 dbz (2). Ref. Z 3 km-Zbg > 10 – Z 2 bg /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).
