Snowfall in Heilongjiang: Climatic Change Characteristics |
| |
| Abstract: | To grasp the climatic characteristics of snowfall in Heilongjiang for better forecast and disaster prevention and mitigation, based on the daily precipitation data and daily weather phenomenon data of 62 stations in Heilongjiang from 1961-2015, we analyzed the snowfall characteristics and climatic trend. The results showed that: the increase tendency of annual mean snowfall in most regions of Heilongjiang was obvious, but the decrease tendency was obvious in the east of the Greater Khingan Mountains; the days of moderate snow and heavy snow and snowstorm all increased, among them, the increase tendency of moderate snow days and heavy snow days were obvious and that of snowstorm days was not obvious, but the light snow days decreased obviously; the average beginning date of snowfall was mainly from late September to October, showing a slightly late trend; however, the average ending date of snowfall was generally from mid-April to early May and was earlier gradually. |
