Abstract

The formation of urban heat islands is one of the effects related to urbanization, as it directly affects thermal comfort. There are several methodologies for its estimation, we can highlight the Gaussian (the best known), whose limita - tion focuses on the analysis of Gaussian surfaces. When the surface presents cases of poly-nucleated conglomerates, another type of approach (non-Gaussian) is recommended, such as the Quantile method. Therefore, this work seeks to estimate the intensity of surface urban heat islands (SUHI) in the long term (2001–2016) with both methodologies (Gaussians and Quantiles). Based on satellite data and the Weather Research and Forecasting (WRF) meteorologi - cal simulation, both with a special resolution of 5 km, for the metropolitan areas of Belo Horizonte, Manaus and Salvador, located in Brazil. Both methods indicate the formation of intense heat islands in the hottest months in the 3 cities studied, with less monthly variation compared to the surface temperature of the Earth’s surface.

利用遥感和天气研究与预报模型研究巴伊亚州贝洛奥里藏特、马瑙斯和萨尔瓦多的地表城市热岛

城市热岛的形成是与城市化相关的效应之一，因为它直接影响到热舒适度。有几种方法可以对其进行估算，我们可以重点介绍高斯方法（最著名的方法），其局限性主要集中在对高斯曲面的分析上。当表面出现多核聚集体时，建议采用另一种方法（非高斯），如量子法。因此，本研究试图利用这两种方法（高斯法和量子法）估算长期（2001-2016 年）的地表城市热岛（SUHI）强度。这项研究以卫星数据和气象研究与预测（WRF）气象模拟为基础，对巴西贝洛奥里藏特、马瑙斯和萨尔瓦多的大都市地区进行了 5 千米分辨率的模拟。这两种方法都表明，在所研究的 3 个城市中，最热的月份会形成强烈的热岛，与地球表面温度相比，每月的变化较小。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
