Why does Pokhara receive highest rainfall in Nepal?

Pokhara receives the highest rainfall in Nepal primarily due to its geographical location and topography. Situated in a valley surrounded by the Annapurna mountain range, it acts as a barrier that traps moisture-laden winds from the southwest monsoon. As these winds rise over the mountains, they cool and condense, resulting in heavy rainfall. Additionally, the valley's positioning enhances orographic lift, further contributing to its significant precipitation levels compared to other regions in Nepal.
