摘要

地表能量不平衡问题一直是陆面过程研究的一个重要科学难题.本文利用在陇中黄土高原观测的陆面过程资料,分析了气候地表能量不闭合度和短期地表能量不闭合度的分布特征,研究了地表能量不闭合度与垂直速度之间的关系,发现地表能量不闭合与垂直速度具有很好的相关性.并且,估算了近地层垂直感热平流通量,分析了考虑垂直感热平流后的地表能量平衡的特征,发现引入垂直感热平流输送对地表能量不闭合度有明显的改进.

The surface energy imbalance problem has been an important challenge in the study of surface land process since it was found in the late 1980s. By utilizing the observed data in the land surface process experiment carried out over the Loess Plateau region in the middle part of Gansu, the characteristics of climate unclosure and short-term unclosure of the surface energy balance are analyzed and the relationship between surface energy balance unclosure and vertical velocity is studied in the paper. It is found that there is a good correlation between surface energy balance unclosure and vertical velocity. Furthermore, the paper estimates the values of vertical sensible heat advection in the surface layer. After considering the vertical sensible heat advection, characteristics of the surface energy balance condition are analyzed again and there is a significant improvement in the surface energy balance unclosure.This means vertical velocity plays an important role in the surface energy buget and the vertical sensible heat advection has a significant influence on the surface energy balance unclosure over the Loess Plateau region.
