Abstract:: In the context of global warming, a correct understanding of the spatial distribution and evolution of cold weather days with different grades in the Loess Plateau can provide a strong reference for disaster prevention and mitigation. Based on the daily minimum temperature data of 58 meteorological stations over the Loess Plateau from 1960 to 2017, we analyzed the spatiotemporal evolution and fluctuation characteristics of cold days(severe cold, major cold, minor cold, light cold, minor cold, cool)and total cold days, and explored their responses to Hiatus phenomenon. The results show that the number of days with different cold grades gradually increased with the decrease of cold grades in the Loess Plateau during 1960—2017, and there were obvious spatial differences; during the study period, the number of major cold days was dominant in most areas of the Loess Plateau, followed by the number of light cold days and cool days; the number of cold days, major cold days, cold days and total cold days showed a decreasing trend, while the number of minor cold days, light cold days and mild cold days showed an increasing trend; the decrease of total cold days was mainly caused by the decrease of major cold days; after the occurrence of Hiatus, the variation trend of cold days, major cold days, minor cold days and cold days was mainly on the high side, while the variation trend of minor cold days and light cold days was mainly on the low side, and the variation trend of total cold days was similar; the variation coefficient of cold days on the Loess Plateau decreased with the increase of cold grades, and the spatial distribution of cold days on the loess Plateau was complex; after the occurrence of Hiatus, the fluctuations of minor cold days, light cold days and mild cold days were mainly on the low side, while those of major cold days were mainly on the low side; the fluctuations of total cold days, cold days and cool days were on the high side and on the low side. In the future, we need to beware of minor cold, light cold and slight cold caused by low temperature and freezing damage to agriculture.
