Abstract
In this paper, we established an ecological type three-dimensional nonlinear mathematical model to study the effect of aerosol particles in increasing rainfall in the regions of less intensity rain. The phenomenon of nonlinearity is based on the concepts of ecology related to growth rate, death rate and interaction process (Smith, 1974). It is assumed that clouds are formed in the atmosphere but are not able to develop uninterrupted rainfall. The rainfall can be enhanced by introducing aerosol particles conducive to raindrops formation from cloud droplets. It is shown that the intensity of rainfall increases as the concentration of externally introduced aerosols and the density of cloud droplets increases. The numerical simulation has also been performed to support analytical results.

Keywords mathematical model;cloud droplets;rainfall;conducive aerosol;simulation.
