Hierarchical Modeling of Vegetation-Climate Interaction and Its Impact on Tropical Climate Variability

[摘要]曾，宁，加州大学洛杉矶分校：植被-气候相互作用的分层模型及其对热带气候变率的影响[j] . PIs建议研究萨赫勒地区植被随气候的变化。还将研究这种相互作用对热带年代际/年际气候变率的影响。pi将使用中等复杂程度的大气-陆地-植被耦合模型。虽然GCM敏感性研究已经证明了森林砍伐和荒漠化等土地利用变化对气候的潜在影响，但自然变化的植被对气候变率的影响受到的关注较少。这项工作很重要，因为它将增加对植被和气候之间相互作用的理解。

AbstractATM-987644Zeng, NingUniversity of California, Los AngelesTitle: Hierarchical Modeling of Vegetation-Climate Interaction and its Impact on Tropical Climate VariabilityThe PIs propose to study how vegetation changes with climate in the Sahel. The consequences of this interaction on tropical interdecadal/interannual climate variability will also be examined. The PIs will use a coupled atmosphere-land-vegetation model of intermediate complexity. While GCM sensitivity studies have demonstrated the potential impact on climate from land-use change such as deforestation and desertification, the impact of naturally varying vegetation on climate variability has received less attention. The work is important because it will increase understanding of interactions between vegetation and climate.
