- Urban “Heat Islands” Make Cities Hotter Than Their Rural Surroundings;
Urban heat island UHI manifests as the temperature rise in built-up urban areas relative to the surrounding rural countryside, largely because of the relatively greater proportion of incident solar energy that is absorbed and stored by man-made materials. The direct impact of UHI can be significant on both daytime and night-time temperatures, and the indirect impacts include increased air conditioning loads, deteriorated air and water quality, reduced pavement lifetimes, and exacerbated heat waves.
Modifying the thermal properties and emissivity of roofs and paved surfaces and increasing the vegetated area within the city are potential mitigation strategies.
A quantitative comparison of their efficacies and costs suggests that so-called cool roofs are likely the most cost-effective UHI mitigation strategy. However, additional research is needed on how to modify surface emissivities and dynamically control surface and material properties, as well as on the health and socioeconomic impacts of UHI.
Human interactions with wildlife are a defining experience of human existence.

Learn About Heat Islands
Where development is densest, the land surface temperature is near 30 degrees Celsius 86 degrees Fahrenheit. Scientists suspect that the urban heat island effect may be one of the factors behind several studies showing that cities influence rainfall in their surrounding area. The heating of the surface and the overlying air creates instability in the atmosphere that encourages air to rise. As it rises, it cools, and water vapor condenses into rain that falls downwind of the city.
Southeast have shown that rainfall downwind of major urban areas can be as much as 20 percent greater than it is upwind areas. To learn more about how the urban heat island and other city traits such as pollution and topography may be influencing rainfall, please read the feature story Urban Rain.

Along with other environmental studies, such as CalEnviroScreen , this research can also help identify and prioritize areas across the state for mitigation. Governments may be interested in the maps of individual cities as a tool for prioritizing local activities such as urban greening and projects focused on cooler roofs and pavements. Over time, it may be possible to track changes in the index that result from climate change or mitigation efforts.
