The way an urban heat island or UHI works is the metropolitan area gets much warmer than the surroundings. The temperature inversion is usually much larger at night than it is during the day and it is larger in the winter than in summer season, and it is most noticeable when winds are weaker. The main cause of the urban heat island is a adjustment of the lands surface by the urban development.
The waste heat is effected by the energy used as a secondary subscriber. As the population and places grow they are inclined to change a greater area of land and have a corresponding increase in our average temperature. This is in part on account of the urban heat island effect, the monthly rainfall for the downward cities is 28% greater than the downwind of cities.
Now do not confuse this with global warming, the meteorologist and scientists have referred this as a phenomenon called the Urban Heat Island Effect or the abbreviation is UHIE. There is not much to argue about whether the urban heat island effect actually exists or not. What is much more debatable is how much is there, and the additional warm affects or the global temperature record. The state of the science to date is that the effect on the global temperature record is a small one.
The urban heat island effect starts when the city temperatures are much higher than those in residential district and the agrarian areas, but because the growing numbers of the buildings have replaced the vegetation and trees. The human activity also generates the heat.
One solution to the urban heat island effect will be in growing plants on the rooftops of apartment buildings and planting gardens on the sky rises. A study that was done in Singapore by top notch researchers have found that these gardens reduce roof temperature by 4°C and that the heat in the rooms apartments are lower. Also a study that took place in Tokyo shows that when the temperature goes down by 0.8°C the rooftop gardens the electric bills are saved and they are approximately S$1.6 million per day would be saved.
Very high temperatures have influenced all the city environments in two ways. 1) This involves air quality, and it is the increase in the temperature and the existence of all the air pollutants, which then we get the smog, and that damages the natural beauty of the earth and makes us humans sick. 2) The focus is on the use of energy or the urban heat island effect which leads to a greater use of the air conditioning units in each persons house, and that directly affects the buildings' energy intake.
There are two major strategies that will help to reduce the UHI effects. 1) Make sure you introduce more green areas into your environment, and that means choosing proper building materials. And to get more plants they will filter the carbon dioxide and other toxins out. 2) u can you use a light-colored roofing material or a reflective coating this will lower your indoor temperatures.
These are the few things you can do to reduce the urban heat island effect, so do it and don't just talk about it.
