Difficulty: EasyWeather Elements, Instruments, and Measurements

At a weather station in Port Harcourt, Nigeria, the maximum thermometer recorded a temperature of 33.0∘C33.0^\circ\text{C} during the day, and the minimum thermometer recorded 21.0∘C21.0^\circ\text{C} at night. What is the diurnal temperature range in degrees Celsius (∘C^\circ\text{C}) recorded for that day?

Answer: 12 °C

Answer

The diurnal temperature range recorded for the day is 12.0∘C12.0^\circ\text{C}.
The diurnal temperature range is defined as the difference between the maximum and minimum temperatures recorded within a single 24-hour day. Subtracting 21.0∘C21.0^\circ\text{C} from 33.0∘C33.0^\circ\text{C} yields 12.0∘C12.0^\circ\text{C}.

Step-by-Step Solution

1
Extract the given maximum and minimum temperature values from the problem statement.
Maximum temperature = 33.0∘C33.0^\circ\text{C}, Minimum temperature = 21.0∘C21.0^\circ\text{C}.
Diurnal range requires the daily maximum and minimum readings.
2
Apply the diurnal temperature range formula.
Diurnal Range=Maximum Temperature−Minimum Temperature\text{Diurnal Range} = \text{Maximum Temperature} - \text{Minimum Temperature}.
The diurnal range represents the total temperature variation experienced within a 24-hour period.
3
Perform the subtraction.
33.0∘C−21.0∘C=12.0∘C33.0^\circ\text{C} - 21.0^\circ\text{C} = 12.0^\circ\text{C}.
Subtracting the minimum temperature from the maximum temperature gives the numeric difference.
