Time series study of urban rainfall suppression during clean-up periodsGeng, Jun 10 October 2008 (has links)
The effect on urban rainfall of pollution aerosols is studied both by data analysis
and computational simulation. Our study examines data for urban areas undergoing
decadal clean-up. We compare the annual precipitation between polluted sites and
relatively clean sites through the time range before and during their clean-up periods to
see how the air quality may affect the precipitation amount. By comparing the annual
precipitation amount between two polluted sites with different elevations we demonstrate
the role that elevation may play in rainfall suppression. Based on the data we collected,
we built a model to analyze the relationship between air pollution aerosols and
precipitation. Finally, we used a model of time dependent condensational aerosol growth
to numerically study the relationship of air pollution aerosols and precipitation amount.
Based on these results, we found a negative relationship of precipitation amount and air
pollution amount; also, the simulation results clearly demonstrated that too many air
pollution particles will deplete the water vapor and suppress further growth of condensation nuclei (CN) toward cloud condensation nuclei (CNN). This study
supported the theoretical explanation on why air pollution could suppress urban rainfall.
