Abstract:
Indian monsoon precipitation is of critical importance for a
very large portion of the world's population. There are proposed
mechanisms that may explain overall and regional changes to observed and
projected Indian monsoon precipitation trends. However, a great source
of uncertainty remains in explaining how the interaction of
anthropogenic aerosols with local precipitation processes and large
scale atmospheric moisture convergence have affected or might affect
these trends. Using a cloud resolving global climate model with a simple
interactive ocean and forced with assimilated aerosol concentrations we
analyze the character of simulated precipitation variability and
discussed how it compares with observationally derived data.
