The climate in urban areas differs from that in neighboring rural areas, as a result of urban development. Urbanization greatly changes the form of the landscape, and also produces changes in an area's air. The study of urban climate is urban climatology. In 1950 Åke Sundborg published one of the first theories on the climate of cities. [1] [2]
Urban climatology is the study of urban climate. It is a branch of climatology that concerns interactions between urban areas and the atmosphere , the effects they have on one another, and the varying spatial and temporal scales at which these processes (and responses) occur.
The World Urban Database and Access Portal Tools (WUDAPT) is a global initiative of tools to create local climate zone maps for a given city using a standard methodology. [1] It has both a database and a portal. The database has hierarchical layers of increasing detail, with data acquired via crowdsourcing methods such as Geo-Wiki. [2]
The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1
A definition of urban heat island is: "The relative warmth of a city compared with surrounding rural areas." [14]: 2926 This relative warmth is caused by "heat trapping due to land use, the configuration and design of the built environment, including street layout and building size, the heat-absorbing properties of urban building materials, reduced ventilation, reduced greenery and water ...

Urban geographers and urbanists [1] examine various aspects of urban life and the built environment. Scholars, activists, and the public have participated in, studied, and critiqued flows of economic and natural resources, human and non ...

[35] [34] For example, the book Life After Carbon documents a number of cities which act as "urban climate innovation laboratories". [36] These cities as laboratories offer an efficient way to detect climate change by looking at the effects of the greenhouse effect on rooftops, street trees, and other environmental variables within a city ...
