Remote Insolation Forcing of Orbital‐Scale South Asian Summer Monsoon Variability

Abstract Whether the South Asian summer monsoon (SASM) is controlled by local or remote insolation at orbital band remains uncertain. Here, we perform a transient simulation forced Earth's parameters between 400 and 350 ka BP, period characterized significant contrast insolation, to identify SASM's response forcing. Simulation results suggest that primary driver of orbital‐scale SASM variability Northern Hemisphere high‐latitude June as opposed insolation. High in Southern might reduce intensity. Remote influences altering latitudinal thermal gradient and, consequently, meridional position high (SAH). The SAH associated with intense convection hence drives shift intertropical convergence zone rain belt. Thus, strongly related
