Droplet growth in a bin warm-rain scheme with Twomey CCN activation

Abstract:

This paper discusses improvements to the bin warm-rain microphysics scheme that applies the Twomey approach to represent CCN activation. The Twomey approach relates the concentration of activated droplets to the maximum supersaturation experienced by the air parcel during activation and thus avoids complications of CCN size distribution and chemical composition that are considered in more complicated activation schemes. When using the traditional Twomey scheme, activated droplets are typicall...
