Weather forecasting models coupled with canopy layer schemes are frequently used to assess the urban heat island (UHI) phenomenon through sensitivity analysis. These models are valuable tools if they are properly tested against field observations. Mughal et al. (2019) (https://doi.org/10.1029/2018JD029796) followed this approach to investigate Singapore's UHI effect within the urban canopy layer. But a lack of field observations for evaluating the model's performance led to simplistic assumptions and wrong interpretations. The major flaws triggered by both circumstances are exposed with the aim that future research does not repeat the same mistakes and can provide the scientific basis to formulate effective mitigation measures.

Mughal等人对“新加坡的城市气候结合局部气候区的高分辨率，多层建模”的评论。（2019）

天气预报模型与树冠层方案结合在一起，经常用于通过敏感性分析评估城市热岛（UHI）现象。如果对这些模型进行了适当的现场观察测试，它们将是有价值的工具。Mughal等。（2019）（https://doi.org/10.1029/2018JD029796）遵循这种方法来研究新加坡在城市冠层内的UHI效应。但是，缺乏用于评估模型性能的现场观察导致了简单的假设和错误的解释。暴露这两种情况下的主要缺陷是为了使将来的研究不再重复相同的错误，并可以为制定有效的缓解措施提供科学依据。
