<h5>Geographical Reasons - The strategic location of India on Map.</h5>India is experiencing more western disturbances in monsoon than usual&nbsp;contributing to extreme rainfall, flash floods and landslides in the Western Himalayan region.What is South West Monsoon?The winds from south West Indian subcontinent is responsible for Monsoon in India , It begins in June and lasts till September and is a major seasonal wind system that brings substantial rainfall to the Indian subcontinent. These winds brings monsoon and hence these are called South West MonsoonThese winds brings moisture from the Indian Ocean and is characterized by heavy rains hence it is crucial for agriculture and water resources in India.What are western disturbances?Western disturbances are storms that originate in the Caspian or Mediterranean Sea, and bring non-monsoonal rainfall to northwest.These western disturbance (extra tropical cyclonic circulations)&nbsp;may be forming closer to India this time when it comes to India it bring strong rains during monsoon and non-monsoon regions.&nbsp;Why Monsoon arrive early in India this year?Under normal conditions, the monsoon winds crosses central Kerala and reaches Karnataka around June 5th , but this year the monsoon winds arrive 10 days prior to its normal timeline due to the conditions which fulfil the onset of monsoons. What Factors contributed to the early onset of Monsoons?<ol><li>When High pressure develops at the Indian ocean region and low pressure develops on the land, then wind flows from High pressure to low pressure and in this case monsoons winds carring moisture flows from ocean to land causing rainfall.</li><li>This high pressure area develops at Mascarene Islands (located at South Indian ocean) and its called Mascarene High.</li><li>This Mascarene High is a key factor in determining the intensity of monsoon. This year a stronger Mascarene High has developed and therefore a strong monsoon winds had travelled.</li><li>A delay in the formation of Mascarene High means delay in monsoons in India.</li></ol>
