Today’s lesson:Define urban micro-climate and urban heat island.Describe the differences between urban and rural

climatic environments.Identify the causes of UHI’s and locate their

characteristics within Hong Kong.

What are micro-climates?

Page 3: Today’s lesson: Define urban micro-climate and urban heat island.

Predict the differences between urban micro-climates and rural environments:

• Insolation (incoming solar radiation) / light• Temperature • Wind• Humidity• Precipitation• Cloudiness / Fog

NOW USE THE GEO-FACTSHEET TO DESCRIBE THE DIFFERENCES

Page 4: Today’s lesson: Define urban micro-climate and urban heat island.

Why do these differences occur?

Page 5: Today’s lesson: Define urban micro-climate and urban heat island.

Define urban heat island:

Page 6: Today’s lesson: Define urban micro-climate and urban heat island.

Predict the temperature data for this urban transect…

Read the 2 articles on the Hong Kong heat-island effect…

• Which areas of HK are warmest?• What figures can you use to support this claim?• What are the reasons for this? Are they because

of structures or human activity?
