Practice objective / multiple choice question 20 from the 2019 Waec Model Questions Vol1 Geography examination.
A weather diagram shows three stations: Station X at the centre (0,0) with pressure 1000 hPa, Station Y 100 km east of X with pressure 1015 hPa, and Station Z 100 km north of X with pressure 1015 hPa. Assume the pressure gradient varies linearly between stations. (a) State the direction of the pressure‑gradient vector at X. (b) Using the Coriolis effect in the Northern Hemisphere, indicate the approximate direction of the wind at X. (c) Estimate the magnitude of the pressure‑gradient force per unit mass, (1/ρ)∇p, in m s⁻², assuming air density ρ = 1.2 kg m⁻³.
