How the Interaction of Heatwaves and Urban Heat Islands Amplify Urban Warming

Received: 29 March 2022;  Published: 06 June 2022;  doi: 10.21926/aeer.2202022

Abstract

An increase in global temperature will likely result in more intense and frequent heatwaves that would last longer. Simultaneously, the growth of urban population requires more areas of land incorporated into urbanization, because most people are expected to live in cities, which will increase the intensity and duration of urban heat islands. However, the extent of the link between global warming induced heatwaves and urbanization caused heat islands is barely understood. Understanding the link [...]
