Dansgaard‐Oeschger Events Recorded in Low‐Latitude Marine Sediments and Teleconnection With High‐Latitude Climate Variations

Abstract Dansgaard‐Oeschger (D‐O) events are millennial‐scale high‐latitude climate oscillations with abrupt climate transitions between stadial and interstadial conditions, which are well recorded in and outside of high northern latitudes. However, their signal propagation mechanisms from high to low latitudes are uncertain. Here, we report a low latitude environmental magnetic record of D‐O events from the South China Sea and compare it with records from different latitudes to discuss the propagation mechanism. Nineteen D‐O events are recorded in our high‐resolution record that reflect evolution of East Asian Summer Monsoon (EASM) precipitation. We propose that D‐O events propagate to low latitudes via influences on the Siberian High, Intertropical Convergence Zone (ITCZ) movement and the EASM. Northern Hemisphere cooling enhances the Siberian High, and shifts the ITCZ southward—a response that weakens the EASM and associated precipitation, with ocean processes regulating heat distribution. Therefore, D‐O signal propagation from high to low latitudes results from air‐sea interactions.
