What unique rainfall pattern characterizes southern Nigeria, where a brief dry spell interrupts the rainy season in mid-summer?
Answer and explanation
Correct answer: B. a bimodal rainfall regime featuring the August break
- Step 1: Southern Nigeria experiences two rainfall peaks, typically in June/July and September/October. Step 2. In August, a temporary decline in rainfall occurs, popularly known as the 'August Break' (or August dip). Answer: a bimodal rainfall regime featuring the August break. Why not the others: Northern Nigeria has a unimodal rainfall pattern (single peak in August); trimodal and constant arid patterns do not describe southern Nigeria.
