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? 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 Why do these differences occur? Define 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?
