Stratosphere–troposphere exchange and surface ozone pollution over tropical regions: a case study of Rossby wave breaking and tropopause folding

Abstract. Stratosphere-troposphere exchange (STE) is a key process by which ozone-rich stratospheric air enters the troposphere, influencing surface air quality. This study analyses an atypical STE event over North America between 6 and 14 March 2016, coinciding with a Phase I oz...
