1. Define “Urban heat island”:
An urban heat island is when urban regions are warmer than their rural surroundings, creating an islands of higher temperature in the landscape.
2. Sketch the temperature variations as shown on the website onto the profile below. Discuss which areas are cooler.
The area of the pond is cooler in surface temperature during the day. Downtown has a cooler air temperature during the day. At night, the rural areas are cooler in both surface and air temperature.
3. How do heat islands form? Describe 2 methods that contribute to higher urban temperatures from heat islands.
Heat islands form on the surface and in the atmosphere. The sun heat drying exposed urban surfaces. 2 methods that contribute to higher urban temperatures are increased energy consumption and elevated emissions of air pollutants.
4. Discuss the environmental benefits/detriments of wintertime and summertime heat island areas.
Detriments of wintertime and summertime heat island areas are the increase in peak electricity demands, higher air temperature, higher water temperature.
5. What are some of the things that can be done to reduce the urban heat island effect?
Increasing tree and vegetative cover, creating green roofs and using cool pavements.
6. What is the temperature variance in green roof vs. traditional roof?
Green roof air temperature is cooler and the traditional roof temperature is up to 90 degrees Fahrenheit.
7. Describe some benefits of green roofs:
Reduces energy use, reduces air pollution, improve human health and improves quality of life.
8. What are the 4 major impacts of urban heat islands?
Increased energy consumption, elevated emissions of air pollutants and greenhouse gases, compromised human health and comfort and impaired water quality.
9. Name 2 human health effects of heat islands
2 human health effects of heat islands are heat cramps and heat strokes.
10. What is a cool pavement?
Paving materials that reflect more solar energy, enhance water evaporation, or have been modified to remain cooler than conventional pavements.
California-list 2 things that are currently being done to help mitigate the effects of urban heat islands?
2 things that are currently being done to help mitigate effects of urban heat islands are to develop and adopt an urban heat island mitigation policy and to support the Community Forest Initiative.
