摘要:

利用“中国西北干旱区陆—气相互作用实验”观测的资料,分析了大气湿度、土壤含水量、与土壤含水量相关的陆面参数及其他陆面参数特征。为了验证新的陆面参数及参数化公式, 将新陆面参数与参数化公式输入陆面模式进行模拟, 将模拟值与观测值进行了比较。结果表明输入新参数及参数化公式的模拟效果更好。

Abstract:

In the paper, by using the data observed in“The Field Experiment on Land - atmosphere Interaction over Arid Region of Northwest China”, characteristics of atmospheric humidity, characteristics of soilwater content, characteristics of land surface parameterswith soil water content and other land surface parameters are analyzed. To validate the new surface parameters and parameterization formulae, the comparison is done between simulation and observation. It is found that the new surface parameters and parameterization formulae are better.

Key words: arid region of Northwest China, hydrometeorology, surface parameter, simulation
