Factors Responsible for Heavy Rainfall in Western India
Recently, due to excessive rainfall, a situation of floods and landslides has arisen in western India, due to which the life of the people has once again been badly affected.
Factors responsible for heavy rainfall:
Topography: The Western Ghats act as a major barrier for the monsoon winds coming from the south-west monsoon. The mountain slope (slope) has a direct effect on the rainfall conditions. The Western Ghats extend parallel to the Arabian Sea coast. It extends from the Maharashtra-Gujarat border to the southern tip of Kerala for about 1,800 km.
Climate Change: As the global temperature increases, the moisture-absorbing capacity of the atmosphere also increases. Ultimately this humidity results in strong convective currents over the Indian landmass during the monsoon season. Oceanographic data from various agencies, including NASA, shows that the surface temperature of the Arabian Sea has been increasing rapidly over the past several years. The higher the surface temperature of sea water, the greater the humidity in the winds that blow over them.
Uncontrolled development: Along with urbanization and other land use, aerosols also contribute to locally heavy rainfall events.
The risk of landslides and flash floods has increased due to overflow from dams. Also, in urban areas, flooding can occur due to excessive rainfall due to storms. Agriculture in these areas is also being adversely affected.
