地表能量平衡成分图制作的相关模型

   1)净辐射通量密度():

 

 

 

式中,下标SL分别表示太阳辐射(短波辐射)(

和长波辐射(>);箭头表示通量方向(为入射,为出射);

   Stefan-Boltzmann

常数; 是空气温度(K); 是水蒸气(mb); 

 是表面发射率; 是表面温度。

2)瞬时潜热通量密度

 

 

式中,G是土壤热通量密度;H是显热通量密度; 

ND是归一化差植被指数; 是体积热容量

  是稳定性校正空气动力学阻力。

有以下两种情况:

对稳定情形,有:

 

 

对不稳定情形,有:

 

式中,g是重力加速度;RiRichardson 

U是风速;z是测量风速和温度的距离表面的高度;d是在高度上的位移; 

粗糙长度;kvon Karman常数,即
