Question map
Among the following places, which one receives comparatively lowest average monsoon rainfall from June to September ?
Explanation
The distribution of southwest monsoon rainfall in the Ganga valley follows a distinct pattern where precipitation decreases from east to west . Southern West Bengal and Eastern Uttar Pradesh are located in the eastern and middle parts of the Ganga valley, receiving higher rainfall, typically between 100 to 200 cm [3]. As the monsoon winds move further inland towards the northwest, the moisture content diminishes. Consequently, Western Uttar Pradesh receives lower rainfall (50-100 cm) compared to its eastern counterpart [3]. Punjab, situated further northwest, is categorized as an area of less to scanty rainfall, often receiving less than 60 cm annually [3]. Official IMD data confirms that Punjab's long-period average (LPA) for the monsoon season is approximately 43.9 cm (439.8 mm), which is significantly lower than the averages for the other regions mentioned [t1]. Therefore, Punjab receives the comparatively lowest average monsoon rainfall among the given options.
