If Clouds Really Had Silver Linings

Evangeline Walker

Abstract


Considering the old adage, that every cloud has a silver lining, this paper considers what conditions would be required to produce clouds with enough silver content to class them as ‘sterling’, as well as the properties the resultant cloud would have, such as density and mass. Taking these results into account, the paper demonstrates, using the Earth as an analogue, the planet required to produce such a cloud would need a surface temperature of 2460K and an atmospheric density of 101872kgm-3 at the planet’s surface.
