| Zusammenfassung |
| We present a parameterisation of aerosol activation, including
co-condensation of semi-volatile organics, for warm clouds that has
applications in large-scale numerical models. The scheme is based on
previously developed parameterisations that are in the literature, but has
two main modifications. The first is that the total aerosol mass is modified
by the condensation of organic vapours entering cloud base, whereas the
second is that this addition of mass acts to modify the median diameter and
the geometric standard deviation of the aerosol size distribution. It is
found that the scheme is consistent with parcel model calculations of
co-condensation under different regimes. Such a parameterisation may find use
in evaluating important feedbacks in climate models. |
