Fig. 6: STEPS: warm and cold components to the total surface precipitation.

The pie chart shows the fractional contribution of the warm (red) and cold (blue) components to the total surface precipitation. a When simulation is run under control, b when cloud base (CB) is lowered (Low CB), c when CCN loading is reduced (Low CCN), d when both CB and CCN are lowered together (Low CBCCN), e when solid aerosol loading is lowered (Low Dust), and f when SIP is switched off (no-SIP).
