Urban heat islands (UHIs) are interesting but concerning situations that can change the weather in cities. Here are some important points about how they work:
Warmer Temperatures: Cities are usually hotter than nearby rural areas. This happens because of all the buildings, roads, and activities that people do. In summer, it’s not uncommon for urban areas to be several degrees warmer.
Changes in Rainfall: UHIs can change how and when it rains in a city. The extra heat can make water evaporate faster, which can lead to stronger but smaller storms. This means one part of the city might get a downpour while another part stays dry.
Air Quality Problems: The higher temperatures can make air pollution worse. This can be bad for people's health. On hot days, you might notice a layer of smog hanging over the city.
More Energy Use: When cities get hotter, people use more air conditioning. This increases energy use, which can cause even more warming.
In short, urban heat islands show us how our city lives can change the local weather. It's something we should pay attention to!
