2. What is the total annual rainfall received by the station?
3. Give one reason justifying that the station is located in the interior of India.
4. What is the mean annual temperature of this station?
5. Which wind brings most of the rainfall to this station? Give a reason for your answer.

Answer 1

i. Annual Range of Temperature = Maximum Temperature − Minimum Temperature

= 34°C − 13°C

= 21°C

ii. Total Annual Rainfall = 0.5 + 0 + 0 + 0.5 + 2.5 + 21 + 35 + 39 + 27 + 10 + 0.5 + 0 = 136 cm

iii. The station experiences an extremely high annual temperature range (21°C), with featuring summers (34°C) and chilly winters (13°C). This extreme variation is typical of a continental climate found further inland, distant from the sea's moderating, equable influence.

iv. Mean Annual Temperature = `(13 + 22 + 26 + 27 + 28.5 + 34 + 32.5 + 32 + 29 + 27 + 19 + 16)/12`

= `306/12`

= 25. 5°C

v. Southwest monsoon winds

Reason: The data show that the majority of the station’s rainfall occurs between the summer months of June and September (122 cm out of 136 cm yearly total), which corresponds to the operating timeline of India's approaching Southwest Monsoon.
