摘要
本文在国外同类模式基础上,结合自己特点建立了一个土壤一植被-大气近地层的相互作用模式。在这个模式中,土壤和植被与大气之间的各种通量输送是与近地层大气进行的,而不是同较高层大气直接交换,更符合实际情况。以大气几十米高处的风、温度、湿度为输入参数,驱动运行本模式,进行敏感性试验,并用有限的观测数据相比较。结果证明,本模式能合理模拟土壤、植被、大气的温、湿以及各种通量的变化。进一步与中尺度大气模式耦合可以用于气候研究。
In this paper, an interactive model between soil - vegetanon - atmospheric surface layer has been designed with some new characteristics on the basis of some similar models. In this model, all flux transfers between soil, vegetation and atmosphere are computed between soil, vegetation and surface layer,rather than higher layer, which is in better agreement with reality. The input parameters including the wind, temperature and humidity at 60 m are used to run the model and do some sensitivity study experiments. The results are compared with limited observed data. The results show that this model can obtain a reasonable simulation for the variations of temperature, moisture and different fluxes in the soil,vegetation and atmosphere. It can be used in the simulation of climate incofporating a mesoscale model.
