Vertical redistribution of a pollutant tracer due to cumulus convection. Final Report, 1980-1984

Technical Report ·
OSTI ID:6185938
Mathematical formalisms that incorporate the physical processes responsible for the vertical redistribution of a conservative pollutant tracer due to a convective cloud field are presented. Two modeling approaches are presented differing in the manner in which the cloud fields are forced. The two approaches give internally consistent results and give results for the convective mass flux. The manner in which the upward mass flux is apportioned to the various cloud classes, however, differs as consequence of the different vertical profile of forcing functions used. This study shows that the concentration increase in the cloud layer due to the venting action of cumulus clouds can be as, if not more important than, the in situ production and this process should therefore be incorporated in regional scale transport models.
