Practice objective / multiple choice question 21 from the 2019 Gce Model Questions Vol1 Geography examination.
At a weather station the sea‑level pressure was recorded at the following times: - 00:00 h: \(1012\) hPa - 03:00 h: \(1008\) hPa - 09:00 h: \(1008\) hPa - 12:00 h: \(1010\) hPa The pressure tendency index (PTI) for a 12‑hour period is defined as the sum of the absolute values of the pressure change in each successive 3‑hour segment, with a sign that reflects the overall change from the start to the end of the period (positive for a net rise, negative for a net fall). Calculate the PTI for the period and state whether it indicates a strengthening low pressure system, a strengthening high pressure system, or a neutral tendency.
