Explanations:Rajasthan and Gujarat are two states in the northwestern part of India, and they are known for their arid and semi-arid climatic conditions. The rainfall patterns in these regions are influenced by their geographical location and the monsoon winds.
Rajasthan is the largest state in India and is mostly covered by the Thar Desert, which is one of the largest deserts in the world. The state receives very little rainfall, with an average annual rainfall of around 600 mm. The monsoon season, which typically occurs from June to September, brings some relief to the region, but the rainfall is still relatively low compared to other parts of India. The western and southern parts of Rajasthan receive the least amount of rainfall, while the eastern and northeastern parts receive slightly more.
Gujarat, located to the south of Rajasthan, also has a semi-arid climate. The state receives an average annual rainfall of around 1,000 mm, which is higher than Rajasthan but still relatively low compared to other parts of India. The monsoon season is the primary source of rainfall in Gujarat, and the western and southern parts of the state receive more rainfall than the eastern and northern parts.
The low rainfall in Rajasthan and Gujarat is due to their geographical location and the influence of the monsoon winds. The monsoon winds, which bring moisture from the Arabian Sea, are not strong enough to penetrate deep into these regions, resulting in low rainfall. Additionally, the presence of the Aravalli Range in Rajasthan and the Vindhya Range in Gujarat can act as a barrier to the monsoon winds, further reducing the amount of rainfall in these regions.
It is important to note that while Rajasthan and Gujarat generally receive little rainfall, there can be variations in rainfall patterns from year to year. Some years may see above-average rainfall, while other years may experience drought conditions. However, the overall climatic conditions of these regions are characterized by arid and semi-arid conditions, which means they generally receive little rainfall.
