Large cities have their own climatic

Pressure gradient is the main driving force that causes the movement of wind from areas of high pressure to areas of low pressure. Commonly, smog is caused by an inversion, in which warm air presses down on a column of cold air. It then introduces the key methodology of urban climatic mapping and elaborates on general urban-climatic-based planning advice for planners using a UCMap.

The existing infrastructure and urban development trajectory determine the opportunities for implementation of low-carbon strategies. Yes, it is a fossil fuel company but far from concealing the truth, Exxon has been more than willing to adapt to changing climate awareness. Having over 64, square miles of water; most of which is a mix of fresh and salt water creates higher levels of humidity and heat in the spring and summer months.

Improved air quality or alleviation of congestion result from policy co-benefits associated with transportation emissions. Challenges for city action to deliver international targets Even with the heightened focus on municipal-level climate action we are still a long way from meeting global emissions reductions targets.

It is also important not to overstate the speed of urban change. Put aside for the moment the absurdity of pinning sole responsibility for the effects of climate change on a handful of companies. Some of world's fastest growing cities over the past 50 years also have among the best standards of living within their nation.

Where I live in New Haven, Connecticut USAwe are witnessing its impacts —warmer winters, sea level rise, and inland and coastal flooding. In the lee of the building there is zone of lower pressure which creates vortices.

Ground-level ozone, or smog, is created by chemical reactions between NOx and volatile organic compounds VOCs in the presence of sunlight.

For example, even though a city may wish to install a bus rapid transit system, it may not have the regulatory authority to do so—that authority may lie with a different government entity such as a regional transportation agency. However, intensity, frequency and length of fogs are much greater particularly under anticyclone conditions.

This study has identified ways to promote the use of urban climatic knowledge in planning. As ground surfaces are heated rapid evapotranspiration takes place.

Sustainable urban planning of high-density cities from the urban climatic point of view is a topical issue for city planners and policy makers.

This warm causes traps cold air beneath it forcing the air to remain stationary. Annual carbon emissions were around 49 GtCO2 inand there is a large gap between what cities can directly reduce and what is needed to meet Paris climate targets.

The second limitation is the existing built environment and development patterns, which set in motion the opportunities and challenges that a city may face as climate policy is developed.

Vehicle emissions, emissions from industrial sites and chemical solvents are the major sources of NOx and VOCs. Unexpected expenditures from storms, flooding, snow removal and drought can lead to major disruptions in business operations and city budgets. Asia and Oceania[ edit ] AmmanJordan has extreme examples of microclimate, and almost every neighbourhood exhibits its own weather.

Much more heat is absorbed and conducted through the material. An example of this is in London which has a very dense population in the town centre with lots of pollution and smoke from cars and industries surrounding the town centre.

Sep 27,  · Most of the world's major cities today have been important cities for several hundred years, so they became important cities before the development of motorized transport (and later refrigeration) that reduced cities' dependence on their surroundings for food.

Climate on a local scale: urban climates Human activity has a big influence on the climate of an urban area. Climate is the long term behaviour of the atmosphere in a specific area, with characteristics such as temperature, pressure, wind, precipitation, cloud cover and humidity etc.

Why Cities?

Cheng Hsien Tan Comparison-Contrast Essay Composition I Xiaoping Du 10/31/12 Growing up in a large city and in a small town Everyone experiences growing up in different places and families/5(1).

Large cities have their own climatic conditions. To what extent is this true? (40 marks) Large cities have their own climatic conditions and can be referred to as having a micro-climate. Micro-climates are small scale variations in temperature, precipitation, humidity.

Why Cities?

Large concrete buildings and roads due to their thermal capacity store and emmit greater heat than the lighter surfaces and vegetation. This keeps urban climates relatively high and the contrast between the urban environment and the rural fringe is greatest at night.

Building materials therefore have. A microclimate is a local set of atmospheric conditions that differ from those in the surrounding areas, often with a slight difference but sometimes with a substantial one.

The term may refer to areas as small as a few square meters or square feet (for example a garden bed or a cave) or as large as many square kilometers or square miles.
