The research highlights how changes in the Northern Westerlies have influenced East Asian summer monsoon precipitation isotope during past abrupt climate events, providing insights into understanding high- and low-latitude teleconnections.
The East Asian summer monsoon (EASM), which sustains the livelihoods of billions of people, is a vast and complex climate system. While its variability during glacial periods has been closely linked to abrupt climate events such as the Dansgaard-Oeschger (DO) events, the role of the Northern Westerlies in modulating EASM moisture transport and isotopic compositions remains poorly understood.
A study in National Science Review reports systematic observations of diazotroph abundance, community structure, and N2 fixation rates in the western North Pacific. Using generalized additive models, the team characterized ecological niches of key cyanobacterial diazotrophs and quantified UCYN-B’s contribution to global N2 fixation. The findings highlight UCYN-B’s pivotal role in marine N₂ fixation and provide new insights into ocean nitrogen cycle and productivity under climate change.
