Previous evidence has showed that the boreal spring Southern Annular Mode ( SAM ) regulates summer monsoon precipitation in East Asian subtropics through the Northern Indian Ocean sea surface temperature ( NIO SST ). This paper further demonstrates how a positive (negative) boreal spring SAM is usually followed by a warmer (cooler) summer over northeast China ( NEC ), suggesting impacts of the SAM even extend to the northern mid‐latitudes. A positive spring SAM usually leads to anomalous anticyclonic sinking motion over NEC during summer through the NIO SST , which results in cloud reduction and changes in radiation, and thus surface warming.
