Ml. Shulman et al., DISSOLUTION BEHAVIOR AND SURFACE-TENSION EFFECTS OF ORGANIC-COMPOUNDSIN NUCLEATING CLOUD DROPLETS, Geophysical research letters, 23(3), 1996, pp. 277-280
Solubilities and surface tensions were measured for difunctional organ
ic acids in various concentrations of (NH4)(2)SO4 and NH4HSO4 aqueous
solutions. Model results using these data indicate that the organic co
mpounds affect cloud droplet growth by two mechanisms: by gradual diss
olution in the growing droplet which affects the shape of the Kohler g
rowth curve, and by lowering of surface tension which decreases the cr
itical supersaturation.
