The findings of monsoons date back to the 1,800 when there were ruling dynasties now they discover that there is some sort of link to the strength and weaknesses of the monsoons now they have also discovered a cave that contains stalagmite that was preserved by the wondrous monsoon rains. Stalagmites are largely made up of calcium carbonate, which precipitates from groundwater dripping from the ceiling of a cave.

Chemical analysis of a 118mm-long stalagmite from Wangxiang Cave, in Gansu province, north-west China, told the history of strong and weak cycles in the monsoon – the rains that water crops to feed millions of people in Asia. Source
