ozone is an important chemical constituent of the atmosphere, and stratosphere it protects the earth surface from harmful uv radiations, such that it is known as “good ozone” while, in the lower troposphere it is a highly oxidizing pollutant and known as “bad ozone”. it is also a greenhoure gas that can affect the climate. hence, the study of spatial and temporal variations of ozone is importan...

Abstract Recent studies have suggested that deep Arctic warming, extending from the surface to upper troposphere, could trigger mid-latitude atmospheric circulation changes, while shallow confined in lowermost induces comparatively weak remote responses. The causes of mid-to-upper tropospheric warming are less clear compared with near-surface warming. Here, we demonstrate a new dynamical mechan...
