Question 16 of 18intermediate🔧 ApplyNumerical2 marks

Calculate the annual range of temperature.

Correct Answer

Step 1: Calculate the Mean Temperature for January Mean Temperature = (Mean of Daily Max. + Mean of Daily Min.) ÷ 2 Mean Temperature (January) = (21.1 + 7.3) ÷ 2 = 14.2°C

Step 2: Calculate the Mean Temperature for May Mean Temperature (May) = (39.6 + 25.9) ÷ 2 = 32.75°C

Step 3: Calculate the Annual Range of Temperature Annual Range = Mean Max. Temperature in May – Mean Temperature in January Annual Range = 32.75°C – 14.2°C = 18.55°C

Therefore, the annual range of temperature is 18.55°C.

Explanation

The annual range of temperature is calculated by finding the difference between the mean temperature of the hottest month (May) and the coldest month (January). The textbook example shows New Delhi (Safdarjung) data where January has a mean temperature of 14.2°C and May has 32.75°C, giving an annual range of 18.55°C.

Solution Steps

  1. Step 1: Calculate mean temperature for January = (21.1 + 7.3)/2 = 14.2°C

  2. Step 2: Calculate mean temperature for May = (39.6 + 25.9)/2 = 32.75°C

  3. Step 3: Annual range = 32.75 – 14.2 = 18.55°C
