Neco Model Questions Vol1 2020 Geography Question 14
Practice objective / multiple choice question 14 from the 2020 Neco Model Questions Vol1 Geography examination.
The diagram shows three isobars spaced 200 km apart with pressures of 1020 hPa, 1010 hPa and 1000 hPa. At the point between the 1010 hPa and 1000 hPa isobars, the pressure gradient is therefore 10 hPa over 200 km. Given a air density \(\rho = 1.2\,\text{kg·m}^{-3}\) and a Coriolis parameter \(f = 0.0001\,\text{s}^{-1}\), the geostrophic wind speed is calculated by \(V = \frac{1}{\rho f}\,\frac{\Delta P}{\Delta d}\), where \(\Delta P\) must be expressed in pascals and \(\Delta d\) in metres. Determine the wind speed in km/h at that point, rounded to the nearest kilometre per hour.
