Policymakers have to assess and optimize neighborhood-scale planning aspects to profit from climate mitigation and adaptation measures due to various thermal environmental concerns. There are many models to evaluate the local thermal environment, but their outputs or complexity limit their application in performance-oriented neighborhood planning. In this study, the Urban Weather Generator (UWG) was updated to meet the needs of neighborhood planners. The model improves the radiation, vegetation, and convective heat transfer calculation processes to better match the actual physical representation of the neighborhood. Besides, the functions of the model are extended to calculate the mean radiant temperature (MRT) and water temperature for the evaluation of outdoor human thermal comfort and blue infrastructure effects. A new graphical interface also makes it easier for planning decision-makers to start quickly. Then, the prediction results of the updated model are evaluated with the neighborhood observations of the hot and humid regions of Guangzhou and Nanning. The air temperature, relative humidity (RH), and MRT results revealed that this novel model performs quite consistently and demonstrated the reliability and computational efficiency of the UWG model. In the early stages of thermal environment evaluation, the UWG model can be used for performance-oriented neighborhood planning.

由于各种热环境问题，政策制定者必须评估和优化社区规模的规划方面，以从气候缓解和适应措施中获益。有许多模型可以评估当地的热环境，但它们的输出或复杂性限制了它们在以性能为导向的邻里规划中的应用。在这项研究中，更新了城市天气发生器 (UWG) 以满足社区规划者的需求。该模型改进了辐射、植被和对流热传递的计算过程，以更好地匹配邻域的实际物理表示。此外，该模型的功能被扩展为计算平均辐射温度（MRT）和水温，用于评估室外人体热舒适度和蓝色基础设施效果。新的图形界面还使规划决策者更容易快速开始。然后，利用广州和南宁湿热地区的邻域观测对更新后模型的预测结果进行评价。气温、相对湿度 (RH) 和 MRT 结果表明，这种新模型的性能相当一致，并证明了 UWG 模型的可靠性和计算效率。在热环境评价的早期阶段，UWG模型可用于以绩效为导向的邻里规划。和 MRT 结果表明，这种新模型的性能相当一致，并证明了 UWG 模型的可靠性和计算效率。在热环境评价的早期阶段，UWG模型可用于以绩效为导向的邻里规划。和 MRT 结果表明，这种新模型的性能相当一致，并证明了 UWG 模型的可靠性和计算效率。在热环境评价的早期阶段，UWG模型可用于以绩效为导向的邻里规划。
