In the face of climate change and constantly progressing urbanization processes, so-called heat islands are observed with growing frequency. These phenomena mainly characteristic large cities, where increased air land surface temperatures form an atmospheric (AUHI) or (SUHI) urban island (UHI). Moreover, UHIs have also been recognized in underground environments many cities worldwide, including...

Despite the fact that presence of a heat island over city was established quite long time ago, now there is no versatile algorithm for determination urban intensity. The proposed models either take into account only one or several factors formation an do not consider physical reasons difference in thermodynamic conditions between and countryside. In this regard, it impossible to make forecast d...

Abstract Urbanization and global warming are two of the major human impacts on environment. The Urban Heat Island (UHI) effect can change precipitation patterns. Global also leads to changes in especially an increase intensity frequency extreme precipitation. With urbanization expected grow future, role UHI a warmer climate is important research question. We present results from 20-year long re...

The non-hydrostatic mesoscale model MM5V3 is used to simulate the wind and temperature fields of the atmospheric boundary layer over Beijing area in summer with the mesh resolution of 1 km. The simulation results show that the numerical model can successfully simulate the urban heat island effect and the wind and temperature fields which are affected by the complicated topography and urban heat...

The urban heat island (UHI) phenomenon has become a serious problem in recent years. It is necessary to study the mitigation methods and quantify their effects on UHI. In this paper, based on the remote sensed data, an empirical model was established as a negative function of land surface temperature (LST) to vegetation coverage. Urban heat island intensity (UHII) was estimated by a robust stat...

The urban heat island (UHI) phenomenon is caused by the anthropic alteration of natural environment expansion, its impermeable surfaces, and activities. In addition, morphology can also contribute to increase in temperature cities. UHI effect be described as an climate that generally characterized higher temperatures densely built-up areas compared surrounding areas. This impacts environmental ...
