Answer 1

1. Chennai ranks second in terms of the amount of rainfall. It receives winter rainfall which is not seen in other cities.

3. Delhi min: 31.3 Max: 16.08
   Kolkata min: 32.1 Max: 21.08
   Mumbai min: 31.83 Max: 22.16
   Chennai min: 33.1 Max: 24.41
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.
