The Convective Tracer Transport submodel
calculates the transport of tracers due to convection.
The scheme
uses the convective mass fluxes and entrainment / detrainment rates from
the chosen parametrisation from the CONVECT
module. Those are internally closed - in case that might be necessary
due to different behaviour below the convective cloud base or at the top
of the convective event. The transport uses a monotonic, positive
definite and mass conserving algorithm following bulk approach.
Entrainment and detrainment are allowed in each layer (also in the
same).
In case of convective precipitation there is a link to the
Scavenging Submodule to keep track of the mutual
dependency of both transport processes.
The original code was
written by Mark Lawrence from the MPI for Chemistry and applied for the
Zhang/Hack/McFarlane convection scheme including bulk and plume ensemble
approach, but the plume ensemble is not implemented by now.
More
information can be given on demand, the code and therefor this page are
still under construction and cannot be released to public......
