Results suggest a general decreasing trend in monsoonal precipitation from 6650 to 2150 cal. (notrickszone.com)
The expansion of monsoonal rains during the early Holocene in the tropical latitudes permitted an extensive spread of moist savanna - type vegetation over the Sahara in North Africa and the Kalahari in South Africa and in broad areas of Brazil, India, and Australia. (britannica.com)
The dynamics of monsoonal circulation are known to be strongly dependent on precession - driven and obliquity - driven changes in insolation. (pubs.geoscienceworld.org)
