Final answer:
Far Western Nepal receives more rain due to the monsoon winds from the Indian Ocean and the Himalayas that cause air to rise, cool, and precipitate. This pattern is influenced by regional topography similar to other mountain ranges like the Southern Alps and the Western Ghats.
Step-by-step explanation:
The region of Far Western Nepal experiences more rainfall due to the monsoon system and the influence of the Himalayas. The monsoon winds bring moisture from the Indian Ocean, and as they encounter the high elevation of the Himalayas, the air rises and cools, leading to condensation and precipitation. The southern side of the Himalayas, which includes parts of Nepal, is greatly impacted by this and receives extensive rainfall.
This phenomenon is analogous to the way the Southern Alps in New Zealand or the Western Ghats in India affect local precipitation patterns, emphasizing the influence of topography on regional climate.
