Description:
On the role of tropopause folds in summertime tropospheric ozone over the eastern Mediterranean and the Middle East Dimitris Akritidis, Andrea Pozzer, Prodromos Zanis, Evangelos Tyrlis, Bojan Škerlak, Michael Sprenger, and Jos Lelieveld Atmos. Chem. Phys. Discuss., doi:10.5194/acp-2016-547,2016 Manuscript under review for ACP (discussion: open, 0 comments) We investigate the contribution of tropopause folds in the summertime tropospheric ozone pool over the eastern Mediterranean and the Middle East. For this purpose we use the EMAC atmospheric chemistry climate model and a fold identification algorithm. A clear increase of ozone is found in the middle troposphere due to fold activity. The interannual variability of near surface ozone over the eastern Mediterranean is related to that of both tropopause folds and ozone in the free troposphere.
