研究成果介紹


Ozone-Circulation Interaction in the Stratosphere
Ozone is a key constituent of the stratosphere that modulates the thermal structure of the atmosphere and prevents harmful ultraviolet radiation from the surface. It is well known that during the Arctic circulation extremes, e.g., Stratospheric Sudden Warming, anomalous high ozone concentration occurred in the polar cap region due to enhanced dynamical ozone transport from the lower latitudes. Our study indicated that significant decreases in ozone were also observed in the tropics, highlighting the global influences of Arctic circulation extremes. We also developed a simplified chemistry-dynamical model (SCDM V1.0), which couples a linear ozone scheme and a shortwave radiative parameterization into a widely used idealized model. The new model is economical and has the advantage of isolating the ozone effect on circulation. Our ongoing work is to use the model for an in-depth study of the role of interactive ozone for the variability of the coupled stratosphere-troposphere system.
