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

An increase in global temperature will likely result more intense and frequent heatwaves that would last longer. Simultaneously, the growth of urban population requires areas land incorporated into urbanization, because most people are expected to live cities, which intensity duration heat islands. However, extent link between warming induced urbanization caused islands is barely understood. Understanding give a new information about catastrophic mitigation strategies. This paper, therefore, quantifies, at sub-continental scale Eastern North America, effects background perturbations by synergies using simulations from Weather Research Forecasting (WRF) model, focusing on responses energy balances, boundary layer height vertical profiles heat, momentum moisture. Results showed exacerbate deepening turbulent height, modifying surface regional winds. The fractional shift latent sensible fluxes consequent changes planetary tends amplify intensity, extensive heatwaves. response ground surfaces lags, while canopy humidity dissipates earlier onset heatwave water evaporates quickly point where there less left for evaporation leaving urbanized regions vulnerable heating. During event, mean wind speed dropped 2.5 m/s, hence cool air available ventilation. deepens maximum 90-m over compared rural this may prolong Based results, it can be concluded best heat-stress management strategies perspectives balance an integral approach lower albedo, flows towards centers.
