(a) Eddy heat flux
(b) LDR
Figure 11: (a) Composite differences in the 850 hPa poleward eddy heat flux between the MOD and CTL runs (former minus latter) based on the three typical cases. The shading interval is 250 K m s−1. (b) As in Figure 11(a) but for the local deepening rate (LDR). The shading interval is 0.1 hPa hr−1.
