The influence of changes in vegetation type on the surface energy budget was studied using the Simple Biosphere Model (SiB) of Sellers et al. (1986). The modeled energy budget response to the conversion of forest to short vegetation or bare soil (deforestation) was investigated with SiB forced by three time--series of atmospheric boundary conditions collected at three different climatic sites: an Amazonian tropical forest, a U.S. Great Plains grassland, and a central Wales spruce forest. The results...

The influence of changes in vegetation type on the surface energy budget was studied using the Simple Biosphere Model (SiB) of Sellers et al. (1986). The modeled energy budget response to the conversion of forest to short vegetation or bare soil (deforestation) was investigated with SiB forced by three time--series of atmospheric boundary conditions collected at three different climatic sites: an Amazonian tropical forest, a U.S. Great Plains grassland, and a central Wales spruce forest. The results show that SiB can simulate realistic surface energy budgets and surface temperatures, and that deforestation may have a significant influellce on the local surface energy budget and surface weather. The influence is especially prominent at the Amazonian and U.S. Great Plains sites, and greater in summer than in other seasons.It was found that atmospheric boundary conditions play a dominant role in determining the degree of changes in the surface fluxes and temperature induced by deforestation; the largest change in latent heat flux appeared at the Amazon site, the largest change in sensible heat flux appeared at the Spruce forest site, and the largest change in surface temperature appeared at the Great Plains site. The Bowen ratios of the SiB sensitivity integrations for each site are comparable with observations. The values of the Bowen ratio and the ratio of latent heat flux to net radiation vary distinctly from site to site, implying that local atmospheric conditions limit the range of changes caused by the vegetation change.

A general circulation model, which has been coupled with the simple biosphere model,was used to assess the influence of anomalous Plateau snow cover in winter on the east and south Asian summer monsoon circulation and rainfall The results point out that the summer monsoon in the east and south Asia would be weakened when the winter snow cover over Plateau is increased The main features are that the precipitation is reduced in the east and south Asian summer monsoon region and the Somali jet,the Indian monsoon trough and the Indian southwest air flow are weakened In addition,we have also examined the sensitivity of the effects of the snow cover over the Eurasia and the east Plateau on the Asian monsoon It is found that the Plateau snow cover was more sensitive than that over Eurasia If only the east Plateau snow cover was increased,the precipitation in the east region of the Plateau, such as in east Asia,would be more reduced,but it might be increased in the area of the east and south India and the bay of Bengal

利用一个耦合了简化的简单生物圈模式的大气环流谱模式(SSiB-GCM),初步探讨了青藏高原冬季积雪异常对东、南亚夏季风环流和降水的影响及其机理。结果表明,高原地区冬季积雪增加将使随后的夏季东、南亚季风明显减弱,主要表现为东、南亚季风区降水减少,索马里急流、印度季风槽和印度西南气流减弱。另外,还提出欧亚大陆雪盖与整个高原雪盖和高原东部雪盖对东、南亚夏季风影响的敏感性问题。与欧亚大陆雪盖相比,高原雪盖是影响东、南亚季风的更敏感区,冬季高原以外雪盖增加,有可能使亚洲季风增强;当高原东部雪盖增加时,高原以东地区及印支半岛降水减少,印度东部、南部和孟加拉湾西北部降水反而增加

The development of a biosphere model, Simplified Simple Biosphere Model (SSiB), and its application in climate studies are briefly described in this paper. SSiB has been validated and calibrated using many observational data. In this paper, the tests using Russian soil moisture data and HAPEX-Sahel data are presented to demonstrate the usefulness of these tests in the elucidation of the mechanisms in land surface processes and the improvement of the model. The influence of observational errors are also discussed. In land surface-atmosphere interaction studies, we mainly discuss the special interaction features in East Asia. In two East Asian studies, although the specified anomaly land forcings from the land surface were in different areas, they both had substantial impact on the summer monsoon. Finally, the application of a coupled regional atmosphere-biosphere model in prediction studies is discussed. Preliminary study indicates that this is a new area with great potential for development.

简要介绍了一个植被模式(SimplifiedSimpleBiosphereModel)的发展过程及其在气候研究中的作用。许多观测资料被用来检验和标定这个模式。文中着重介绍了俄罗斯土壤湿度资料和非洲的HAPEX-Sahel观测资料如何帮助我们改进模式和对陆面过程的机制的认识,对观测误差的影响也作了讨论。在地气相互作用中,着重讨论了东亚地气作用的特征。在文中介绍的两个东亚地区的试验中,尽管地面的异常被假设在东亚的两个不同的地区,但都对夏季风传输途径上的降水有很大影响。最后用一个区域模式对陆面模式在预测试验中的应用作了简介。初步的结果显示,这将是一个有很大发展潜力的新领域。
