Neco 2023 Geography Question 47
Practice objective / multiple choice question 47 from the 2023 Neco Geography examination.
A weather station recorded the following data: at 0900 hrs the temperature was \(30^{\circ}\text{C}\) with relative humidity \(70\%\); at 1500 hrs the temperature was \(28^{\circ}\text{C}\) with relative humidity \(80\%\). Using the approximation \(T_{d}=T-\frac{100-\text{RH}}{5}\) to estimate dew point \(T_{d}\), (i) calculate the dew point for each time, (ii) find the average dew point for the day, and (iii) state whether fog is likely in the evening if fog forms when the dew point is within \(2^{\circ}\text{C}\) of the ambient temperature at 1500 hrs.
