Impact of typhoon Soudelor on ozone and water vapor in the Asian monsoon anticyclone western Pacific mode
Ozonesonde measurements from Hong Kong and Naha are combined with satellite observations to investigate the vertical structure of ozone and water vapor around the tropopause during typhoon Soudelor over the northwestern Pacific in 2015. The results show that the tropopause height is decreased compared to the mean tropopause during 2000–2017 in the western Pacific mode of the Asian summer monsoon anticyclone (ASMA). The vertical transport associated with Soudelor decreases the ozone concentration by 60% in the upper troposphere. Further the equatorward transport from high latitudes around the western Pacific mode of the ASMA increases ozone concentration by 40% in the lower stratosphere. Cross-tropopause transport of water is observed above typhoon Soudelor, and water vapor to be enhanced at 80–100 hPa compared to nontyphoon regions. Dehydration is observed below the tropopause around the eye of Soudelor.
期刊介绍:
Atmospheric Science Letters (ASL) is a wholly Open Access electronic journal. Its aim is to provide a fully peer reviewed publication route for new shorter contributions in the field of atmospheric and closely related sciences. Through its ability to publish shorter contributions more rapidly than conventional journals, ASL offers a framework that promotes new understanding and creates scientific debate - providing a platform for discussing scientific issues and techniques.
We encourage the presentation of multi-disciplinary work and contributions that utilise ideas and techniques from parallel areas. We particularly welcome contributions that maximise the visualisation capabilities offered by a purely on-line journal. ASL welcomes papers in the fields of: Dynamical meteorology; Ocean-atmosphere systems; Climate change, variability and impacts; New or improved observations from instrumentation; Hydrometeorology; Numerical weather prediction; Data assimilation and ensemble forecasting; Physical processes of the atmosphere; Land surface-atmosphere systems.
