A reduction of the solar wind during a prolonged solar minimum event would cause more galactic cosmic rays to enter the earth's atmosphere which would promote
more aerosol formation thus more cloud nucleation.

The
aerosols catalyze the
formation of ice in the clouds, which could increase precipitation, although
more research needs to be done on that linkage, Creamean said.
Despite its smaller ash cloud, El Chichn emitted
more than 40 times the volume of sulfur - rich gases produced by Mt. St. Helens, which revealed that the
formation of atmospheric sulfur
aerosols has a
more substantial effect on global temperatures than simply the volume of ash produced during an eruption.
Even though open windows bring in
more ozone from outside, the reduction in the indoor limonene concentration and SOA
formation strength
more than make up for it, as less secondary organic
aerosol is formed inside.
New research reveals insights into how black carbon

The suggested hypothesis, is that in regions devoid of dust (e.g., over the large ocean basins), the
formation of cloud condensation nuclei takes place from the growth of small
aerosol clusters, and that the
formation of the latter is governed by the availability of charge, such that charged
aerosol clusters are
more stable and can grow while neutral clusters can
more easily break apart.
If a cloud doesn't form then because of lack of
aerosols to start
formation, chill that sucker down some
more to form ice crystals and it should make its on substrate to form.
These clouds then glaciate in higher levels, which could result in either
more or less vigorous precipitation
formation depending on the background
aerosol levels and atmospheric stability (Khain et al., 2004).
On the other hand, if some of the anthropogenic
aerosols act as ice nuclei, supercooled clouds could be converted into ice clouds by the glaciation indirect effect (Lohmann, 2002), resulting in
more efficient precipitation
formation.
It is vital for climate change scientists to discover
more about how
aerosols affect the
formation of clouds and weather, says Chungu Lu, program director of the National Science Foundation's Division of Atmospheric and Geospace Sciences that financed the research.
