Fig. 3: Response of cloud ice in IWP percentile and temperature space in the GSRM experiments.

Fractional increase per TS warming of ice mixing ratio at fixed temperature and fixed IWP percentile in (a) the +4K experiment and (b) the global warming experiment. The white dashed line shows the 7 % K−1 isoline where the increase in ice mixing ratio approximately corresponds to the increase in boundary layer specific humidity. The IWP response from Fig. 2 is reproduced in the upper panel of a, b.
