| Opis: | The alteration of the natural landscape due to the process of urbanization is becoming increasingly common in modern times. People generate a significant amount of artificial energy in cities. Through asphalt and concrete surfaces, we alter both the energy and water balance, and with the increasingly frequent high-rise construction, we also influence local air circulation. Thus, humans, with their own heat input, denser built-up areas, and absence of vegetation, modify air temperature, relative humidity, wind direction and speed, and rainfall height. All these changes manifest in the environment in the form of specific "urban climate," characterized by higher temperatures than those in the surrounding countryside. The heat island of Dravograd, the city of Slovenj Gradec, and Ravne na Koroškem is most pronounced in the centers of the places, from where it spreads in different directions depending on the various weather types. In all three locations, the shape of the heat island is influenced not only by building density, population density, and anthropogenic energy input but also by relief, larger water surfaces, and green areas. The shape and intensity of the heat island change throughout the day. Temperature maxima and minima develop in different parts of the places during the day. |
