Based on the reanalysis data of ERA-Interim from 1979 to 2019, the spatial distribution of monthly mean, extreme and severe Wind Chill Temperature (WCT) in East Asia were studied. Results show that in the three months of winter, the WCT in East Asia decreases from south to north with strong local characteristics; the lowest extreme WCT mainly occurred in Northeast Inner Mongolia, eastern Mongolia and Heilongjiang; comparing the three months in winter, the months with the lowest monthly mean WCT, the lowest extreme WCT is January. The highest frequency of WCT appears in February. WCT in most parts of East Asia is determined by temperature, and the wind speed has the most significant effect on WCT in China and Mongolia Border Area (Mongolia and Eastern Inner Mongolia) and the northern part of Qinghai Tibet Plateau. In addition, the negative correlation between extreme wind cold temperature and wind speed is the strongest in Beijing-Tianjin-Hebei Urban Agglomeration.
