Global Warming in The Urban Heat Island

The influence of UHI is closely related to residents of the city center and its surrounding areas. Although UHI develops well in winter, the area and strength of UHI will decrease in the summer. However, because the original temperature is high and winter is easier to identify than UHI, UHI is much more powerful. Due to the maximum UHI intensity and wind speed, the cloud amount and the precipitation have a negative correlation. As wind speed, cloud cover and precipitation increase, the strength of UHI decreases.

Specifically, this event, known as the "city heat island effect", is a report showing that concrete and most urban infrastructure absorbs heat in a way that functions as a catalyst for global warming and climate change. This situation is effective in most cities, even suburbs all over the world. As this concept continues to spread to every corner of the earth, the city becomes increasingly warmer and people are more prone to health problems related to overheating.

Along with the worldwide population growth and the development of the city center, the heat generated from the human activity and impermeable surfaces leads to a climate known as Urban Heat Island (UHI). Urban heat islands are defined as closed isotherms. This usually refers to the surface (canopy) of air near the ground, which is relatively warmer than the surroundings. Usually, high temperature is recorded in the center of the central city. By changing the land cover from natural vegetation to building materials, short wave energy (heat) is absorbed during the day and stored in low albedo asphalt, concrete and glass. Distributing extra heat becomes even more difficult as it absorbs hot air in building materials and in places close to each other. In addition, excessive use of air conditioning, reduction of heat island effect, release of waste heat to the atmosphere, rise in temperature

As global warming progresses, the heat island effect in urban areas becomes even stronger. The combination of air pollution and increased heat will continue to exacerbate allergies and respiratory diseases. In parks and villages, cherry blossoms are blooming in an unexpected period and will not sync.

Skeptics makers of global warming prevention say that there is a possibility that incorrect measurements will be obtained if weather station is installed in urban area. According to them, the data has been destroyed by the city's heat island. It is the effect of high concentration of carbon dioxide from urban traffic, asphalt that absorbs a lot of heat, and from many families and businesses in populated areas. Skeptics of global warming also believe that models used to predict the future of the earth under global warming are unreliable. They believe that the sun, clouds, gas, glaciers and the ocean are the cause of the weather, but other factors, including several factors we currently do not know about, are similar. According to skeptics of global warming, the computer model only guesses what will happen in the future in the future - climatologists will not deny this - and that can be said that the speculation is very bad. After all, if we can not accurately predict the weather a week later, how can we predict the climate of the world for 100 years?
