Response of a global circuit model with stratospheric aerosol to cosmic ray flux changes and its impact on the climate change

摘要

A new model of the global circuit has been constructed that treats more realistically than previous models the external influences due to varying charged particle fluxes from space, the internal variability due to the transport of radon by atmo spheric dynamics, and the varying aerosol populations. Here we present results for the variability of the global circuit due to the variations of the aerosol populations in the stratosphere and troposphere; the variability of the cosmic ray flux especially for little ice age period.
