چکیده
The paper is dedicated to stability and bifurcation analysis of diffusion growth equation in its complete form, which includes curvature term and chemical composition term. Authors show that critical point on the Kohler curve is the point of saddle-node bifurcation. The time scale associated with this point which can be interpreted as time scale of aerosol activation is estimated analytically. Also the analysis of the more complicated case when the aerosol growth is accompanied by decrease of surrounding humidity has been done. The second saddle-node point was found in this analysis. At last the numerical calculation of hysteresis profiles of supersaturation and aerosol wet radius in adiabatic vertically-oscillating air parcel has been done. The article is interesting and I recommend it for publication

The authors discuss cloud droplet activation and deactivation in terms of saddle-node bifurcation. By doing so they can employ a nonlinear dynamic approach to study the properties of such processes. Specifically, they approximate the drop growth by diffusion equation to a normal form of a saddle-node bifurcation (df/dt = a + fËĘ2) and therefore they could use the properties of such form to stud...
متن کاملOn the CCN [de]activation nonlinearities
We take into consideration the evolution of particle size in a monodisperse aerosol population during activation and deactivation of cloud condensation nuclei (CCN). Our analysis reveals that the system undergoes a saddlenode bifurcation and a cusp catastrophe. The control param5 eters chosen for the analysis are the relative humidity and the particle concentration. An analytical estimate of th...

This manuscript describes CCN measurements in a polluted coastal area. The CCN concentrations are combined with size distribution measurements to derive cut-off diameters for activation. These are related to measurements of chemical composition (in particular the HOA fraction). A sensitivity study compares actual CCN concentrations to CCN concentrations predicted for pure ammonium sulfate aeros...
