2000~2019年东北地区积雪物候时空变化
|
Abstract:
使用MODIS积雪产品数据探究了2000~2019年东北地区积雪日数、积雪初日和积雪终日的时空特征(分布和变化)。研究得出：东北地区积雪物候在空间上具有明显的纬度分异和垂直分异规律，积雪日数减少，积雪初日和积雪终日提前。
The spatial and temporal characteristics (distribution and variation) of snow cover days, snow cover start and snow cover end and their responses to climate in Northeast China from 2000 to 2020 were explored using the MODIS snow product dataset and ERA5 climate dataset. The results show that the phenology of snow cover in Northeast China has obvious latitude and vertical differentiation in space, the number of snow cover days decreases, and the first day of snow cover and the end of snow cover are advanced.
