Urbanization has a marked effect on the reproduction and other ecological and behavioural traits of many living organisms, including birds. In migrant birds, survival and reproductive output is influenced by the (mis)synchronization of arrival with the availability of resources. Many recent studies have shown that arrival timing is related to temperatures en-route and at destination. Because ur...

The coupling between the transport and magnetic topology is an important issue because the structure of magnetic islands, embedded in a toroidal equilibrium field, depends on the nature of the transport at the edge of the islands. Measurements of modulated heat pulse propagation in the DIII-D tokamak have revealed the existence of self-regulated oscillations in the radial energy transport into ...

1. introduction the long-term result of cooperation between environmental factors and circulation patterns determines the arrangement of type and manner in temperature heat islands in geographical areas. the knowledge about space dispersion in geographical areas provides the grounds for sound programming and proper environmental decision making. the information about time and place distribution...

Near the Atacama Desert, Tacna city in Peru is among largest arid cities with constant urban development, thus understanding of surface thermal pattern needed. We propose a comprehensive study heat island phenomenon, objective (1) determining spatial and temporal variations islands (UHIs), period 1985 to 2020; (2) analyzing relationship between UHI influencing factors such as vegetation, area, ...

This research examines the relationship between surface kinetic temperature (SKT), land cover, and the Normalized Difference Vegetation Index (NDVI) for a small city in the Midwestern United States. Color aerial photography was examined to create high resolution maps of land cover for 377 random quadrats. Average NDVI for each quadrat was determined from hyperspectral aerial imagery, whereas th...

Many studies have found that larger parks might be needed to counteract the Urban Heat Island effects typical in densely populated Asian megacities. However, it is not easy to establish large parks to serve as urban cool islands in Asian megacities, where little space exists for large urban neighborhood parks. Officials in these cities would rather use small areas by replacing heat-absorbing ar...

Abstract Rapid land use change in urban areas creates a unique climate, which risks the health of its inhabitants. The climate is attributable to phenomenon recognized as Urban Heat Island (UHI). Under such circumstances, regions become hotter than their rural surroundings, creating an island higher temperatures. Human exposure excessively warm heat islands, particularly humid climates like Ind...

BACKGROUND Because of the warming climate urban temperature patterns have been receiving increased attention. Temperature within urban areas can vary depending on land cover, meteorological and other factors. High resolution satellite data can be used to understand this intra-urban variability, although they have been primarily studied to characterize urban heat islands at a larger spatial scal...

As one of urban eco-environmental contents, urban heat island is very significant. Nowadays, the temperature in urban is higher than the surrounding natural terrain, as the result of vegetation cover declining and impervious surface increasing, coupled with the influence of anthropogenic heat discharge. In recent years, it is possible to study the urban heat island and its formation mechanism, ...
