The Role of Deep-Convective Cloud Transport in the Redistribution of Tropospheric Chemical Species
深对流云输送对于对流层O3、NOx在分析的作用

A three-dimensional model of hailstorms coupled with chemistry transport module was used to study the role of deep-convective transport in the redistribution of chemical species of low soluble gases such as O 3 and NO 2 The model simulates the process and character of a single-cell cumulus cloud The results of cloud transport model show that the strong vertical transport in the cloud could bring low O 3 and high NO 2 in the lower troposphere to the upper troposphere rapidly and efficiently, and cause the redistribution of chemical species Near the cloud top, high O 3 of stratosphere intrudes into the troposphere when convection penetrates into the stratosphere It shows that convective activity of cloud could not only transport the pollutants in the boundary layer to the upper level, but turn over the chemical species between the troposphere and the stratosphere for the entrainment of cloud
