The city is more hot in comparison to rural areas. It is universally recognized. Why is the city seen to be hot? Especially in the center of the city, it is felt more hot, but in the rural areas around the city it is relatively less hot. For example, in the summer the urban climate is very warm and the warmth is fixed and felt for a long time. But the opposite conditions prevail in the rural areas.
Generally, it is believed that the factories and machinery are more in town, traffic overload, and due to smoke and carbon emissions, and due to the decrease of the trees, it is felt more hot than the village. But just because the big cities are now becoming hit island or the thermal island? Due to the hot warming of spring flower buds have started to bloom in the city long before the autumn also. Due to excessive summer due to the fog in the winter of the city but not very much. But the fog is still seen in people in the rural areas.
Why is hot due to some things, hot air produces more, what causes damage due to heat, greenhouse effect, black smoke etc. We all know. But here there are many more things that the students do not know about ordinary people or science students. But these things work as an influencer in the main place. These will be discussed now.
High high concrete corridors prevent air flow. Not only do not stop, due to the location of these buildings, a channel of air flow is created. Due to these reasons, instead of being cold in any area, some places get a little cold wind. The evaporation level increases due to warming, but thermal reduction is less. Due to the advanced technological engineering, water drains out from the rain water and the molten snow drains out.
Again, the ice in the temperate country can not last long as the ice is sprinkling salt. These pitch pour roads and building materials can easily absorb heat. But wood houses or grasses, roads or soil absorbs less heat than these. If we assume that the buildings are almost the same, and only on the night they put their absorbed heat out on the roof, then there is an important condition. That is, a cold air layer is created on the same row building. This layer prevents the hot air from the ground and creates a trap of hot air. If the amount of air pollution in the whole city is high and the presence of contaminated substances in the air is high, then due to such heat trap, the situation may become worse. Even though this may go out during the hot night, there will be no cold environment in the country like the rural areas. The action that is discussed so long, it is difficult during the daytime, [1].
Concrete, bitumin or asphalt etc., the roads that are made are much more in heat capacity. Due to sunlight in the southwest of the United States, it is very hot. The amount of heat on the surface where it gets heated is very horrible. For example, the surface of the road made by asphalt can warm up to 70 degree Celsius in hot summer. Where the skin of human body is burnt at 44 degrees Celsius, the temperature is more than 26 degrees higher. That means if someone is injured in the car accident in the street, it will harm the body even after the damage caused due to the accident. Even standing in the parking lot, the whole body from the legs will become uneasy.
It is also worth noting that due to the extreme heat, there is a situation in the environment where the plants also become the cause of environmental pollution. In the journal Environmental Science and Technology, last year, a paper was published, where it is claimed that the city's plants, especially shrubbery plants, often help in creating contaminated substances in the environment. It is also shown in the study that when a city's temperature increases greatly and the hot air flows through the city, then these plants produce special chemical components and increase the amount of ozone gas in the environment. At the same time, the temperature of the surrounding environment also increased. Therefore, planting trees should be stopped, but not so. Here the trees do not harm the environment themselves, but rather the surrounding hot environment forces them to do so.
From this, it is understood that malnutrition is not only responsible for the heating of machinery or car smoke or from the chimneys in the factory. The elements that we use to create something can also cause warmer growth. And this warmth of the area is called hot island which is called hot island. To implement all the concepts of Sustainability, we have to look at these small things. Otherwise, there will be no benefit at all for the construction of green structures, green environment construction, green transportation system, and the huge amount of money being thrown under the green project will not benefit at all.
Using the science we need to make the right decisions and make a plan on which the whole work will be done. This will save you in all directions and create a beautiful society and beautiful environment. In the previous article, it was said that the damage done by the increase in the heat of the earth has been lost. There is no way to correct the mistakes that have happened, but learning from the mistakes and planning according to the laws and environment laws will reduce the losses.
