Question

Study the graphs given in the figure and answer the following questions:

1. What difference do you find in the rainy seasons of Chennai and other cities of India? Why?
2. What similarity do you see in the temperature curves of Delhi and Kolkata?
3. Calculate the average range of minimum and maximum temperatures of all the four cities.
4. In which city is the range minimum? What can you infer from this?
5. In which city is the range maximum? What can you infer from this about its climate?
6. Based on the temperature and rainfall of Mumbai, comment upon its climate.
7. Classify the cities as cities with equable and extreme climates.

Answer 1

1. Chennai ranks second in terms of the amount of rainfall. It receives winter rainfall which is not seen in other cities.
2. From the temperature curves, Delhi and Kolkata seem to have extreme temperatures.

3. 	Delhi	Kolkata	Mumbai	Chennai
   Avg. Max. Tem.	41° C	36° C	34° C	39° C
   Avg. Min. Tem.	7° C	9° C	17° C	21° C
   Range of Tem.	34° C	27° C	17° C	18° C

4. Mumbai has the minimum range of temperature compared to other cities. Mumbai’s location on India's western coast results in minimal temperature variations. The fundamental reason for this is the mixing of vapour from evaporating water bodies into the atmosphere. The vapour in the air absorbs and stores heat emitted by the land. The temperature in coastal areas is stable.
5. In Delhi, the temperature range is at its maximum. We can conclude from this that Delhi has an extreme or continental climate, with very hot summers and very cold winters, due to its location deep within the subcontinent, far from oceanic influences.
6. The Climate of Mumbai is a Tropical wet and dry climate. Mumbai’s climate can be best described as moderately hot with a high level of humidity.
7. Extreme Climate: Delhi, Kolkata.
   Equable Climate: Mumbai, Chennai
