1. Introduction Assessment of the physical factors controlling the coverage and albedo of marine boundary layer (MBL) clouds remains a pressing challenge. The speed at which the stratocumulus (Sc)-to-cumulus (Cu) transition (SCT) occurs in air masses downstream of the eastern subtropical ocean basins determines the albedo of the tropics, and similar cloud transitions in postfrontal air masses are important for determining midlatitude storm-track albedo. These transitions in cloudiness are

dependence of in the derivation. Therefore, in this study, we assume is constant with height for simplicity. Also, is assumed to have a fixed value of 2.1 g m −3 km −1 , which is typical for the MBL clouds in the subtropics and tropics ( Albrecht et al. 1990 ). With Eq. (6) , integrated liquid water path from the cloud base to z can be written as By substituting from Eq. (6) into Eq. (3) and dividing Eq. (3) by , the decrease in with increasing altitude can be given by The

and Hartmann 1993 ). Cumuli, on the other hand, play a fundamental role in the regulation of ocean surface evaporation and convergence of moisture into deep convective regions (e.g., Tiedtke 1989 ; Neggers et al. 2007 ), and therefore the global hydrological cycle. The transition from shallow cloud-topped MBLs in the cool subtropics to broken trade cumulus over the warm tropics ( Bretherton and Wyant 1997 ; Wyant et al. 1997 ; Sandu and Stevens 2011 ) occurs over all subtropical ocean basins
