1. Calculate the total annual rainfall experienced by the station.
2. What is the annual range of temperature?
3. On which coast of India does the station lie? Give the reason for your answer.

Answer 1

1. Annual rainfall = Sum of rainfall in all twelve months
   Therefore, annual rainfall is 129 cm.
2. The annual range of temperature = Maximum temperature − minimum temperature.
   36.2°C − 24.5°C = 11.7°C
3. The station lies on the southeastern coast of India.
   Reason:
   Maximum rainfall occurs in the months of October and November (30.6 cm and 35.0 cm), which is typical of the Retreating Monsoon Season, common along the Eastern Coast (e.g., Tamil Nadu coast).
