Part 3/11:
In contrast, urban centers with substantial concrete and asphalt, such as Bukit Timah, absorb and retain heat, raising ground temperatures. Thermal camera measurements reveal ground temperatures of about 50°C in these heat-trapped areas—a stark difference from the cooler spots surrounded by greenery.
The Spatial Disparity of Heat: Mapping Vulnerability
Singapore's heat isn't uniformly distributed; it varies significantly across the island. A series of maps showcase this variation:
- Physical exposure map highlights areas facing the highest ambient temperatures, with colors indicating temperature ranges predominantly between 29°C and 30°C.
