(...) Because the initial response to cloud seeding is local, high-resolution, limited-domain simulations are especially useful to explore the efficacy of seeding. One recent study of this type (Wang et al., 2011a) found that cloud brightening is sensitive to cloud dynamical adjustments that are difficult to treat in current GCMs (Sections 7.4.3 and 7.5.3) and concluded that the seeding rates initially proposed for cloud seeding may be insufficient to produce the desired cloud brightening.
