Changes in the East Asian subtropical jet stream. (a), (b) Composite vertical cross-section of zonal wind (850–150 hPa) averaged from 110° to 150°E during Period 1 (1981–2002) and Period 2 (2003–2020), respectively. (c) Composite difference between Period 2 and Period 1. The dots indicate significance at p < 0.05. The maps are plotted using GrADS v2.2.1 (http://opengrads.org/).
