Describe any three facts which affect the mechanism of monsoon
Answers
The factors that is responsible for monsoon in India are-
The differential heating and cooling of land and water-The difference in temperature over land and water creates a low-pressure over the land mass in India. This low pressure attracts winds from high pressure area.
The shift of the position of Inter Tropical Convergence Zone-The equatorial Inter Tropical Convergence Zone, which is a low pressure belt of highly unstable weather, moves northward towards India. This shift is also a cause of the onset of monsoon in India.
The presence of high pressure area east of Madagascar-The intense high pressure area that is formed of Madagascar, at approximately 20 degree south over the Indian Ocean causes the wind to flow towards the low pressure over the Indian land mass.
The heating oh Tibetan Plateau-The Tibetan Plateau which gets intensely heated during summer, results its strong vertical air currents and the formation of low pressure over the plateau at about 9 Km above sea level.
