Neco 2021 Geography Question 2
Practice objective / multiple choice question 2 from the 2021 Neco Geography examination.
The weather diagram shows three concentric isobars centred on a low‑pressure system L. The outer isobar is 1010 hPa, the middle is 1005 hPa and the innermost is 1000 hPa. Station A is located 100 km due east of L, on the 1005 hPa line. Assuming geostrophic balance, air density \(\rho = 1.2\,\text{kg\,m}^{-3}\) and Coriolis parameter \(f = 1.0\times10^{-4}\,\text{s}^{-1}\), determine (i) the wind direction at station A and (ii) the approximate wind speed in m s\(^{-1}\). Use the pressure difference between the outermost and innermost isobars (10 hPa) over the radial distance of 200 km.
