Question

Study the Climatic data of the station given below and answer the questions that follow:

MONTHS	JAN	FEB	MAR	APR	MAY	JUN	JUL	AUG	SEP	OCT	NOV	DEC
TEMP (°C)	22	23.5	28	29	32	32	31.6	31	29.8	27	25.5	24.2
RAIN (cm)	0.3	0.2	0.7	-	5	28	45	54	30.5	15	0.5	-

1. What is the annual range of temperature of the station mentioned above?
2. What is the total annual rainfall received by the station?
3. Why would it be correct to presume that the station is located in the coastal region of India, and not in the interior?
4. Name the wettest month.
5. Name the wind that brings most of the rainfall to this station.

Answer 1

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

= 32°C − 22°C

= 10°C

ii. Total Annual Rainfall = 0.3 + 0.2 + 0.7 + 0.0 + 5.0 + 28.0 + 45.0 + 54.0 + 30.5 + 15.0 + 0.5 + 0.0

= 179.2 cm

iii. The station experiences an equable/maritime climate with a low annual temperature range (10°C). Coastal areas benefit from the sea's moderating influence, resulting in more consistent temperatures throughout the year compared to the continental interior, which endures dramatic seasonal variability.

iv. The wettest month is August, receiving 54 cm of rainfall.

v. The Southwest Monsoon winds provide most of the rainfall to this station, as the heavy precipitation is focused during the summer monsoon months from June to September.
