Table 3. Summary of the Four Main Sensitivity Simulations Performed With the LMDZ GCM


Name	Description

Control	Control simulation described with the actual AR4 version of LMDZ4.
Diffusive advection	Same as control but a simple upstream scheme [Godunov, 1959] is used rather than the second order advection scheme [Van Leer, 1977; Hourdin and Armengaud, 1999]. This is the simulation described by Risi et al. [2010b] and provided to SWING2.
Sigmah/10	Same as control but the sub-grid-scale variability in water vapor used to predict large-scale condensation and nebulosity is divided by 10.
epsip/2	Same as control but the precipitation efficiency in both the convective and large-scale precipitation schemes was divided by 2.
