Can tiny aerosol particles make tropical convective clouds grow stronger? For decades, scientists have debated this question because aerosols can change how cloud droplets form, grow and release latent heat. One proposed pathway, known as condensational aerosol convective invigoration, requires clouds to contain high water-vapor supersaturation. Under such conditions, adding aerosol particles can create many new droplets, enhance condensation, release additional latent heat and potentially strengthen convective updrafts.
