NIM陆面过程模式的研究Ⅱ:青藏高原夏季陆面过程的数值模拟

A Study of NIM Land Surface Process Model Part Ⅱ:A Numerical Simulation of Land Surface Process over Qinghai Tibet Plateau in Summer

摘要:

采用南京气象学院(NIM)5层陆面过程模式,利用1979年5～8月“青藏高原气象科学实验”资料模拟和分析了夏季青藏高原不同地区的陆面特征和地表能量特征。并将模拟值与根据观测资料计算得到的感热和潜热以及观测得到的净辐射、土壤温度、土壤热通量进行了对比。结果表明,NIM5层陆面过程模式可以模拟青藏高原夏季不同下垫面情形下的能量交换过程。

Abstract:

Using five layer nanjing institute of meteorology land surface process model(NIMLSP)for data on meteorological scientific experiment over the Qinghai Tibet Plateau from May to August in 1979, characteristics of land surface process and energy transport were both simulated for different regions over the plateau for summer season. Simulations of either sensible heat flux or latent heat flux were compared with its calculations from observed data and with measurements of net radiation, soil temperature and soil heat flux respectively. Results show that this model can be applicable to simulation of energy exchange for summer over various underlying surfaces in the Qinghai-Tibet Plateau.
