  • 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).
