A considerable body of work demonstrates that the low latitude summer monsoons have weakened in response to the Northern Hemisphere trend of decreasing summer radiation. In some regions, the latitude of the Intertropical Convergence Zone (ITCZ) appears to have migrated over the course of the Holocene, also in response to weaker northern hemisphere summer insolation. In other areas, the rainfall belt appears to have been characterized by expansion and contraction. Paleoclimate evidence is also mounting that Holocene orbital trends affected the intensity or frequency of tropical Pacific interannual variability (El Ni\u00f1o-Southern Oscillation; ENSO) has varied during the Holocene. These insolation-induced trends, as well as higher frequency variability in the low-latitude hydrological cycle have influenced the distribution of precipitation on land, with consequences for societies. With collaborators, we have studies the mechanisms of orbital and volcanic influence on the tropical hydrologic cycle.<\/p>\n<p>&nbsp;<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Modeling the Hydrologic Cycle Since the early Holocene, the amplitude of the seasonal cycle of incoming radiation has decreased in the northern hemisphere and increased in the southern hemisphere.
