Waec Model Questions Vol1 2017 Geography Question 50
Practice objective / multiple choice question 50 from the 2017 Waec Model Questions Vol1 Geography examination.
The weather map shows two parallel isobars: Isobar A carries a pressure of 1012 hPa and Isobar B a pressure of 1000 hPa. The distance between the two isobars is 200 km. Assuming the pressure gradient is uniform between them, calculate (a) the pressure gradient in hPa per kilometre, and (b) the geostrophic wind speed using the formula \(V = \frac{1}{\rho f}\,\frac{\Delta p}{\Delta n}\). Use air density \(\rho = 1.2\,\text{kg m}^{-3}\) and Coriolis parameter \(f = 1.0\times10^{-4}\,\text{s}^{-1}\). Give the wind speed in metres per second, rounded to the nearest whole number.
