Delhi records 43.5C, but why feels hotter?

Delhi experienced a temperature of 43.5 degrees Celsius, yet the heat felt more intense than the reading suggests. A team conducted an experiment using a thermal camera to measure surface temperatures in both indoor and outdoor environments. The study aimed to understand why the heat was perceived as more severe. Researchers observed that surfaces like roads and buildings absorbed and retained heat, contributing to the overall warmth. The data revealed that shaded areas had lower temperatures compared to direct sunlight. The findings highlight the impact of urban infrastructure on perceived heat. Understanding these factors can help in developing better heat management strategies.

The study provides insights into how urban environments affect heat perception, which is crucial for climate adaptation efforts.
