There are also several cases where the two studies» assessment of consistency with the observations of a model's seasonal variations in
low cloud reflectivity differ radically.
According to theory (and computer models), seeding marine stratocumulus clouds with copious amounts of tiny sea water particles could significantly enhance cloud droplet number concentration, and
thereby cloud reflectivity and longevity.
He calculates that to achieve the desired effect
on cloud reflectivity would require treating them with «a cupful» of salt per km2 per hour.
Moreover, the linear relationship that the Zhai study fits between the seasonal variability derived relationship of low
cloud reflectivity with SST and ECS is dominated by «bad» models that are inconsistent with the observational constraint.
They also act as cloud condensation nuclei (CCN) around which clouds can form, and thereby
influence cloud reflectivity and cloud lifetime (indirect effects).
The same goes for schemes involving ocean pipes and stimulating biologically - driven increases in
cloud reflectivity.
It would be possible to add a linkage from the surface temperature to
the cloud reflectivity to see how this could stabilise the surface temperature.
