Answer 1

1. Chennai’s main rainy season occurs later (around October - November) it receives significant rainfall from the retreating/northeast monsoon - whereas the other cities get most rain during the southwest monsoon (roughly June–September). This difference is due to the Bay of Bengal/retreating monsoon affecting the southeast coast.
2. Both Delhi and Kolkata show temperatures that rise gradually from January to May and then fall gradually from August to November.
3. Average maximum and minimum temperature ranges (from the graphs)
   • Delhi: about 6°C (min) to 41°C (max).
   • Kolkata: about 9°C to 37°C.
   • Mumbai: about 16°C to 34°C.
   • Chennai: about 21°C to 39°C.
4. Chennai has the smallest range (most equable temperatures). This indicates an equable (maritime‑influenced) climate with smaller seasonal variation.
5. Delhi has the largest temperature range (i.e., the most extreme). This reflects a more continental climate with greater seasonal extremes.
6. Mumbai’s temperatures are moderately warm year‑round (approx. 16°C - 34°C), and it receives heavy monsoon rainfall (very high values in June - July). On that basis, Mumbai is described as hot and humid with a strong southwest monsoon.
