Observational analysis reveals urban heat island intensity peaks at night in Shenyang's local climate zones, suggesting heat management strategies are needed.
Key Points
Urban heat island intensity reached a maximum of 7.6 °C at night in built-type LCZ 2, indicating significant nighttime warming.
Field measurements and multi-source meteorological data were analyzed across seven local climate zones during summer.
The study uncovered variations in thermal environment characteristics at different summer stages, emphasizing urban cold island effects.
Highlights the need for targeted heat risk mitigation strategies in severe cold regions, particularly for urban areas.
