摘要
采用Ｊ．Ｗ．Ｄｅａｒｄｏｒｆｆ￣［１］地表植被参数化方案，利用Ｐ－σ原始方程５层模式￣［２］，分析了青藏高原有植被和无植被两种不同下垫面情况下的大气响应，结果表明有植被下垫面通过增加向大气输送潜热通量，加强了高原上空的热低压，增强了高原北部的热成风，加强了高原南侧的季风环流，使青藏高原及我国东南地区的降水增多。
The P-σ five-level primitive equation model is adopted in connection with a vegetationparameterizat ion scheme to invest igate atmospheric response to Tibetan heat source with vegeta-tion available and without. Evidence sugests that with vegetation present,latent heat flux isstrengthened into the air, thus enhancing the thermal depression over the highland,thermalwind in the north and monsoon circulation on the south side,thereby causing increased rainfall inSE China.
