Explanations:Western disturbances are a significant weather phenomenon that affects the northwestern parts of the Indian subcontinent, particularly during the winter months. These disturbances originate from the Mediterranean Sea and the Caspian Sea, moving eastward and bringing moisture-laden winds to the region. The primary states affected by Western disturbances include Punjab, Haryana, and parts of Rajasthan.
The term "Western disturbance" refers to the extratropical cyclonic storms that originate in the Mediterranean region and move eastward, crossing the Middle East and the Iranian plateau before reaching the Indian subcontinent. These disturbances are characterized by their ability to bring significant rainfall to the affected regions, especially during the winter season. The rainfall from Western disturbances is crucial for the agricultural activities in these regions, as it provides much-needed moisture during the dry winter months.
It is important to understand the geographical and climatic context of the states mentioned in the question. Punjab, located in the northwestern part of India, is one of the primary states that receives rainfall due to Western disturbances. The other states mentioned in the options, such as Kerala, Karnataka, and West Bengal, are influenced by different weather systems. Kerala and Karnataka are primarily affected by the Southwest and Northeast monsoons, while West Bengal's rainfall is driven by the monsoon systems.
Therefore, among the given options, Punjab is the correct answer as it is the state that receives significant rainfall due to Western disturbances. This understanding of the geographical and climatic patterns is crucial for comprehending the impact of different weather systems on the Indian subcontinent.
