An Overview of Land Proxies of Paleomonsoon

Abstract

The monsoon circulation is at its best in this region of the world, with unusual characteristics such as its burst or abrupt change from the dry to the wet season and irrational patterns of rainfall. Historical monsoon records can be used to better understand monsoon dynamics, and pollen assemblage could also refer to land-use activities. The Indian subcontinent has a unique monsoon system that differs from other systems in terms of its focal points, air masses, and precipitation mechanism. This system disrupts and reverses the typical global atmospheric circulation, making it one of the world's most densely populated areas. Information about the most recent paleomonsoon was gathered via isotope studies, tree rings, and other natural archives like speleothem. Tropical teak trees from peninsular India may be able to recreate the sub-seasonal monsoon, according to oxygen isotope studies. Similar to how oxygen isotopes from Indian speleotherms have recently provided proxy evidence for rainfall. A speleothem with good coherence can be seen from a distance.
