This photograph is taken on a summer afternoon when are supposed to the sky is completely cleared but one can see that does not look sharper the city due to pollution and other factors. The effect of UHI in the center of Barcelona It is due to increased vehicle traffic, the increase in population and the increase of concrete constructions basically nothing green buildings. Mean annual temperature in the center of the city was 18.2 degrees centigrade, while in the rural area on the outskirts of Barcelona was 16.8 degrees centigrade. ![ingrese la descripción de la imagen aquí][2] Then you need to take into account the average relative humidity is about 75%, this causes the sensation of temperature increase 1 degree more. Seeing the concentration of buildings in the city center and the outskirts is cleared predominating vegetation, out there we have practically the answer to the temperature difference. To reduce the UHI effect considers the opportunity to create more green areas, for example through deeds underground in the city (the underground Railroad works, parking, etc.). It should be encouraged in carrying out construction green walls. Currently the city of Barcelona is promoting renaturation of decks, roofs and balconies. This consists in filling of groundcovers to help capture rainwater and absorption of CO2. [1]: http://i.imgur.com/7SVijpQ.png [2]: http://i.imgur.com/d6xxG3A.jpg?2
