A case analysis of turbulence characteristics and ozone perturbations over eastern China

Our knowledge of the vertical variabilities in turbulence and ozone perturbation free atmosphere is severely limited because scarcity high-resolution observation data. Based on Thorpe method, a new set sounding data Shanghai, China, was used herein to analyze distributions perturbation. The region which activity relatively frequent spans from 5-15 km middle upper troposphere. Due combined action large wind shear thermal convection, low-troposphere stratification conditions are conducive generation large-scale turbulence. Turbulence has certain effect atmospheric concentration exchanges; most regions located near turbulence, partial pressure perturbations occur. In troposphere, profile influenced by static instability, while stratosphere, both convection play important roles emergence perturbations.
