Q1With reference to the North Bay of Bengal ozone finding described by PIB on 10 August 2026, consider the following statements: 1. An unusually thick ozone layer was detected at about 21–23 kilometres, below the usual peak concentration altitude of about 25–30 kilometres. 2. Its observation during both day and night suggested that sunlight-driven photochemistry was unlikely to be the primary cause. Which of the statements given above is/are correct?
Both statements are correct. The unusual layer was found at about 21–23 kilometres rather than the usual peak altitude of about 25–30 kilometres. Day-and-night persistence supported a mainly dynamical explanation: transport of ozone-rich air followed by downward motion and compression.
