2014/12/12
We introduce a probability density function (PDF)-based scheme to parameterize cloud fraction, average liquid water and liquid water flux in large-scale models, that is developed from and tested again...
GEWEX Cloud System Study (GCSS) cirrus cloud working group: development of an observation-based case study for model evaluation
GEWEX Cloud System Study cirrus cloud working group observation-based case study model evaluation
2014/12/10
The GCSS working group on cirrus focuses on an inter-comparison of model simulations ranging from very detailed microphysical and dynamical models through to general circulation models (GCMs). The pas...
A simplified treatment of surfactant effects on cloud drop activation
A simplified treatment surfactant effects cloud drop activation
2014/12/9
Dissolved surface active species, or surfactants, have a tendency to partition to solution surface and thereby decrease solution surface tension. Activating cloud droplets have large surface-to-volume...
