The present study examines the role of tropical cyclones in the enhancement of tropospheric ozone. The most significant and new observation reported is the increase in the upper-tropospheric (10–16 km) ozone by 20–50 ppbv, which has extended down to the middle (6–10 km) and lower troposphere ( < 6 km). The descent rate of enhanced ozone layer during the passage of tropical cyclone is 0.8–1 km day−1, which is three times that of a clear-sky day (non-convective). Enhancement of surface ozone concentration by ∼ 10 ppbv in the daytime and 10–15 ppbv in the night-time is observed during a cyclone.
