摘要：Based on the analysis of Asian temperature, the Asian Warming Hole (AWH) index is proposed in this paperto measure the intensity during the cold events process under the background of global warming in the early21st century winter. The results show that the Asian continent is indeed experiencing a cold stage in theearly 21st century winter, but it is just in a cold phase and will become warmer in the future. The relationshipof AWH with atmospheric circulation is statistically close. Moreover, the sea surface temperature (SST) leadof 6 months, shows a higher correlation coefficient with AHW index. The SST anomalies over mid-latitudeand high latitude Pacific regions may play an important role in Asian cold events in winter, but it is not stableas a precursor factor. The mechanism of this phenomenon is very complex, the atmosphere can reflectsome characteristics, while ENSO cycle signal is more and more significant in recent years.
