摘要:
使用CoLM模型,以青藏高原冰冻圈观测研究站设在唐古拉综合观测场的气象资料作为驱动资料,在青藏高原多年冻土区的唐古拉地区开展了单点模拟试验。通过和该站点同期实测资料对比发现:CoLM模型对高原多年冻土区的辐射通量各分量的模拟效果较好;对潜热通量的模拟误差较大,感热和地表热通量的模拟相对较好;模型能够很好地模拟活动层浅层土壤温度,但随着深度加深,模拟的温度较观测值有所低估。研究表明CoLM模型能较好地模拟多年冻土区地表与大气的能水交换过程,对其进行一些适应性改进后将能得到更好地应用。改进模型的土壤水热参数化过程尤其是添加未冻水参数化方案是将其应用到冻土区首先要解决的问题;再者扩展模型的模拟深度也...
Abstract:
Using meteorological data collected by Tanggula Comprehensive Observation site on the QinghaiXizang Plateau as force data, the applicability of CoLM model (singlepoint) on permafrost regions of QinghaiXizang Plateau was analyzed by comparison of simulated and observed values. Results show that: CoLM model is capable of providing good simulations of the evolution of surface radiation fluxes; simulated latent flux do not match well, but sensible flux and ground surface thermal flux are shown to be basically in agreement with observations; the model could simulate shallow soil temperature quite well with correlation coefficients over 0.97, but model underestimates simulated temperatures more with the deeper depth. It is indicated that CoLM model can simulate water and heat exchange process between land and atmosphere well, and will be better if several necessary improvements were developed. Improving model frozen soil hydrothermal parameterization scheme, especially adding supercool water process in frozen soil, is a top priority. Further expansion of simulation depth is also necessary.
