Abstract Ozone in the troposphere is a pollutant and greenhouse gas, it crucial to better understand its transport from ozone‐rich stratosphere. Tropopause folding, wherein stratospheric air intrudes downward into troposphere, enables stratosphere‐to‐troposphere ozone (STT). However, systematic analysis of relationship between folding tropospheric ozone, using data that can both capture folding...

     Lali sub-surface structure, with a NW-SE Zagros trending is located in Dezful Embayment. To determine the folding mechanism, structural geometric parameters including limbs dip, amplitude, wavelength, and crestal length were determined in four stages during deformation. In order to investigate the lateral folding mechanism, these geometric parameters were analyzed in three parts in the Lal...

Abstract. Tropopause folds are the key process underlying stratosphere-to-troposphere transport (STT) of ozone, and thus they affect tropospheric ozone levels variability. In present study we perform a process-oriented evaluation Copernicus Atmosphere Monitoring Service (CAMS) reanalysis (CAMSRA) O3 during folding events over Europe for time period from 2003 to 2018. A 3-D labeling algorithm is...

[1] The height, pressure, and temperature of the cold point tropical tropopause are examined in three 140 year simulations of a coupled chemistry climate model. Tropopause height increases approximately steadily in the simulations at a mean rate of 63 ± 3 m/decade (2s confidence interval). The pressure trend changes near the year 2000 from 1.03 ± 0.30 hPa/decade in the past to 0.55 ± 0.06 hPa/d...

Tropopause folds are the main mechanism underlying stratosphere-to-troposphere transport and influence tropospheric composition weather systems by triggering convection. Here, we present global climatology of tropopause in Copernicus Atmosphere Monitoring Service (CAMS) Modern-Era Retrospective analysis for Research Applications, version 2 (MERRA-2) reanalysis atmospheric products time period f...
