Abstract

Initial plume rise of the pollutant emitted by biomass burning and its subsequent transport have been investigated at specific locations in southeast-Asia. Rapid vertical transport of chemical species in the convections driven by both biomass burning and cumulus activity was reproduced with a mesoscale meteorological model and an advection/diffusion model of chemical species. Strong fire in large area sometimes organizes deep convection up into free troposphere (such as 3000-4000m). This type of convection is relatively weak compared with tropical cumulus convection. However, the convection by fire can efficiently carry pollutants into free troposphere, since it develops directory over emission source area. Results of this study can be usef
