This paper demonstrates the development of a model designed to estimate concentrations associated with a source
situated in complex terrain. The model is designed to provide estimates of concentration distributions and is thus
primarily suitable for regulatory applications. The model assumes that the concentration at a receptor is a combination
of concentrations caused by two asymptotic states: the plume remains horizontal, and the plume climbs over the hill.
The factor that weights the two states is a function of the fractional mass of the plume above the dividing streamline height. The model has been evaluated against data from four complex terrain sites. The evaluation shows that the model performs at least as well as CTDMPLUS (Perry, S.G., 1992.

本文演示了开发的一个模型，旨在估计与源相关联的浓度位于复杂地形。该模型被设计为提供的浓度分布的估计，因此主要适用于监管应用。该模型假定在一个受体的浓度是一个组合由两个渐近状态引起的浓度：羽保持水平，并在山上爬。权重的两个状态的因子是一个函数的分数的分数的羽以上的分割流线高度。该模型进行了评估，对来自四个复杂的地形网站的数据。评价结果表明，该模型至少执行以及ctdmplus（Perry，球，1992。ctdmplus，附近的一个复杂地形源扩散模型。第一部分：技术形态。应用气象学报31，633 - 645），一个更全面的模型设计的复杂地形应用。R 2001 Elsevier科学有限公司保留所有权利。
