摘要提供了全球和季节性的气候-植被生物物理过程（VBP）相互作用强的地区的评估。VBP的存在和VBP对气候的影响程度进行了评估的基础上观测到的全球降水的模拟技术的大气环流模式耦合到三个陆地模式，具有不同程度的复杂性VBP表示。据估计，模拟的VBP对降水的影响约为全球观测降水量的10%，陆地降水量的40%;最强烈的影响是在季风区。其中，VBP对西非，南亚，东亚和南美季风的影响最大。确定了北方高纬度地区植被-降水相互作用的具体特征。不同区域的主要影响季节因区域气候特征和地理特征而异。研究了VBP对表面能和表面张力的影响。
Abstract A global and seasonal assessment of regions of the earth with strong climate–vegetation biophysical process (VBP) interactions is provided. The presence of VBP and degree of VBP effects on climate were assessed based on the skill of simulations of observed global precipitation by two general circulation models of the atmosphere coupled to three land models with varying degrees of complexity in VBP representation. The simulated VBP effects on precipitation were estimated to be about 10% of observed precipitation globally and 40% over land; the strongest impacts were in the monsoon regions. Among these, VBP impacts were highest on the West African, South Asian, East Asian, and South American monsoons. The specific characteristics of vegetation–precipitation interactions in northern high latitudes were identified. Different regions had different primary impact season(s) depending on regional climate characteristics and geographical features. The characteristics of VBP effects on surface energy and w...
