An urban heat island is described as metropolitan area or a city that is particularly hotter than the rural areas that surrounding it because of the activities of the human. The difference in the temperature always higher during the night than at the day, and generally when winds are not strong. Urban heat island is generally apparent during the winter and summer. The modification of land surfaces is the main reason for the urban heat island effect. The second contributor is the losing of heat created

of urban heat islands and possible remedies to the problem are vital in the cause of balancing human activities with environmental sustainability. The urgent and imminent environmentally and economically damaging effects of urban heat islands are concerning topics which necessitate equally as drastic solutions, some of which have already begun to be instated, but may not go far enough in protecting our planet. This paper discusses the present measures put in place to help improve urban heat islands

The urban heat island (UHI) is a metropolitan area with a relatively higher temperature compared to other surrounding rural areas. This relatively flat megacity houses more than ten million people with half of the population residing in the Seoul National Capital Area. The density of the city remains high with 17,288 people per square mile. With the climate on the border line of humid subtropical and humid continental, the metropolitan infrastructure and human activities causes the city to be more

The term ‘urban heat island’ refers to the localized increase in temperature associated with an urban area. The UHI is an example of unintentional climate modification when urbanization changes the characteristics of the earth’s surface and atmosphere. It was observed that the UHI effect might result in minimum urban temperatures being 5-6° greater than the surrounding countryside. In the case of London, mean annual temperature was 11°C, while the surrounding countryside was 9.6°C and the suburbs

how an urban heat island occurs. An urban heat island poses many serious threats as it raises the temperature significantly at night and can cause many fatal health risks during the day. Although urban heat islands seem drastic, there remains ways that could potentially reduce the effects. Minimizing the effect of the urban heat island can be accomplished by increasing the amount of vegetation, which includes trees and natural grass, around new parks and recreational facilities. An urban heat island

global warming but also the Urban Heat Island (UHI) effect. Apart from causing the rise of temperature in urban areas, UHI effect also induces some undesirable impacts to Hong Kong citizens who are living in the urban areas. We shall never underestimate the potential dangers caused by the UHI effect and we should treat it more seriously. This paper will give a brief introduction on UHI effect, its influence and the possible measures that can deal with it. Urban Heat Island (UHI) effect describes predominately

low-solubility compounds (Andreae 2008) In a study of New York City, Hosannah (2014) found that particle size distribution with a high volume of fine mode particles in urban areas can suppress precipitation. Particle size distribution with a high volume of coarse mode particles (with giant cloud condensation nuclei) enhanced precipitation totals. Urban effects also changed spatial precipitation patterns. Jin et al (2005) found weekly signals of aerosol optical thickness for summer months in AERONET measurements

Description A heat wave is a period of excessive heat, which last two or more days. Heat Waves lead to illnesses and could be fatal with prolonged exposure to these extreme conditions. High humidity can increase the heat even more. Heat is very deadly because it is a silent killer. Heat related illness and death can occur due to exposure in one day however it has a cumulative effect on the body. It is a threat to the public health in 1995 between 14 and 20 July 485 Chicago residents died directly
