Why is the summer moonsoon shortest in the far-west of Nepal?

The summer monsoon is shortest in the far-west of Nepal primarily due to its geographical location and topography. This region lies in the rain shadow area of the higher Himalayas, which block moisture-laden winds from reaching it effectively. Consequently, the far-west experiences reduced rainfall and a shorter monsoon season compared to other parts of Nepal that are more directly influenced by the monsoon currents. Additionally, local climatic patterns further contribute to this variability in monsoon duration.
