摘要：

The acceleration of global urbanization has increased the frequency of the urban heat island (UHI) effect and heatwaves, which seriously endanger human health. We used Shenzhen as a case study to examine the daytime and nighttime differences in UHI intensity (UHII), considering different local climate zones (LCZs) and sea-land breezes. The diurnal UHII was >3 degrees C for 52% of the study period, whereas the nocturnal UHII was >3 degrees C for only 26% of the study period. The average diurnal and nocturnal building-type UHII values were 2.77 and 1.11 degrees C higher than those of the natural type, respectively. Sea breezes alleviated the UHI effect with a linear correlation coefficient of -0.68601 between them. Moreover, diurnal and nocturnal UHII showed differences across different gradients, which can help guide urban planning.
