Question

Study the graphs given in 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. In which month does India experience the highest rainfall?
8. 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: Max (40°C) – Min (15°C) = 25°C
   Kolkata: Max (38°C) – Min (17°C) = 21°C
   Mumbai: Max (35°C) – Min (20°C) = 15°C
   Chennai: Max (35°C) – Min (24°C) = 11°C

4. The range is minimum in Delhi. The climate of Delhi is an overlap between monsoon-influenced Humid subtropical and semi-arid with high variation between summer and winter temperatures and precipitation.
5. The range is maximum in Chennai. Chennai has a Tropical wet and dry climate. The city lies on the thermal equator and is also on the coast, which prevents extreme variation in seasonal temperature.
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. India experiences the highest rainfall in the month of July.
8. Extreme: Delhi, Kolkata.
   Equable: Mumbai, Chennai
