积雪是陆地水文循环以及大气过程的重要组成部分,它调节了陆地和大气之间的能量交换,对下垫面的能量收支平衡与水热迁移起重要作用。在介绍积雪特性参数确定方法及积雪水热运移规律的基础上,对国内外现有积雪模型进行了分类和总结,并指出未来在积雪特性参数化方案、数值模拟计算、尺度转换等方面还应进行更深入的研究。
Snow is a key component of terrestrial hydrological cycle and atmospheric process,which regulates the energy exchange between land and atmosphere and plays an important role in energy balance and water and heat transfer of land surface.This paper introduced the measurements of snow characteristic parameters and water and heat transfer mechanism of snow,classified and summarized the existing snow models,and pointed that the suggested potentials in future studies will focus on parameterization scheme of snow characteristic parameters,numerical simulation and scale transformation.
