Tropopause height characteristics associated with ozone and stratospheric moistening during intense convective activity over Indian sub-continent

In this present investigation, a threefold analysis has been portrayed to comprehend the atmospheric dynamics at the Tropopause height on both short and long term basis over the Indian sub-continent. The Tropopause height as determined from the gridded temperature profiles from ERA Interim reanalysis is using a concept of “threshold lapse-rate”. It has also been noticed that an exchange between water vapour and ozone occurs along the Tropopause (100hPa) region during occurrences of deep moist convection. The eastern Indian coastal region experiences enormous convective strength during summer (March–May), hence an increase in specific humidity (as proxy of water vapour) with subsequent decrease in ozone levels in the east-coastal stations are found comparable with the inland stations. Again, the vertical convective transport during deep convection has been found to be supported by stronger vertical wind in the coastal regions compared to inland locations. Finally, it has been comprehended that vertical transport of water vapour gradually decreases in the eastern Indian coastal regions while not much change has been noticed in inland regions.
