India exhibits a significant variation in average annual rainfall due to its diverse geography. States like Assam, located in the northeastern region, experience high rainfall due to the monsoon winds and proximity to the Himalayas. In contrast, states like Haryana and Uttar Pradesh, situated in the northern plains, receive comparatively lower rainfall. Understanding this variation is crucial in the context of agricultural practices and water resource management across different states. Which one of the following sequences of decreasing average annual rainfall is correct?

Rainfall in India mainly occurs in the months of July, August, and September . The Indian rains are chiefly orographic in nature. As a result, the regions situated on the windward side receive greater rainfall than the regions located on the leeward side. Only a scant amount of rainfall is received from cyclones and convectional rainfall. Monsoon in India is irregular, not well distributed, and unpredictable. While there are floods in some regions, the other regions face drought. Regions receiving hefty rainfall (more than 200 cm ) Slopes of the Western Ghats and the Western Coastal Plains. Meghalaya Hills (Garo, Khasi, and Jaintia), the southern slopes of the Eastern Himalayas, Assam, Arunachal Pradesh, and West Bengal. Regions receiving moderate rainfall (100-200 cm) The southern part of Tamil Nadu and the northern parts of Andhra Pradesh. Middle Ganges Valley, some parts of the Western Ghats, Eastern Maharashtra, Madhya Pradesh, and Odisha. Regions receiving low rainfall (50-100 cm) Parts of the Deccan plateau consisting of the regions of Karnataka, Andhra Pradesh, and Tamil Nadu. Eastern Rajasthan, Punjab, Haryana, and Kashmir. Regions receiving scanty rainfall (5o cm and less) Northern parts of Kashmir, southern Punjab, and western Rajasthan. The rain shadow regions of the Western Ghats lying in the Deccan Plateau. The table below will explain how the annual average rainfall changes state-wise due to their respective location. State Average rainfall Assam 2,818 mm Bihar 1,326 - 1,186 mm Uttar Pradesh 1,025 mm Haryana 617 mm Hence, the correct sequences of decreasing average annual rainfall is Assam, Bihar, Uttar Pradesh, Haryana. Central and northern parts of India get occasional rainfall during winter. Weak temperature cyclones lead to rainfall in Delhi, Haryana, Punjab, and western Uttar Pradesh. This rainfall benefits the rabi crops. Northeastern areas of the country also receive winter rainfall. In October and November, the northeast monsoon receives heavy moisture while blowing over the Bay of Bengal and cause enormous rainfall over the coast of Tamil Nadu and the southern tip of Andhra Pradesh.
