urban canyon effect

The urban canyon effect occurs when tall buildings line both sides of city streets, creating a corridor resembling a canyon. This layout can trap heat, directing sunlight downward and preventing it from escaping, which raises temperatures in the area. Additionally, the tall structures can block wind flow and disrupt air circulation, leading to decreased air quality and stagnation. This phenomenon makes urban areas hotter and often more polluted than surrounding regions, impacting comfort and health for residents. Essentially, the "canyon" formed by buildings influences local climate, similar to a natural canyon trapping heat and air.
