“…Further, the Convective Inhibition (CIN) values also (Figure 9g) are high in increased urbanization simulations. These results of higher heat fluxes, temperatures, deep PBL, lower humidity, and CAPE for the dry phase on November 30 for the Chennai urban region corroborate with the findings from Rath and Panda (2019) and indicate that the local urban effects dominated during the dry phases. An interesting result is that the mean surface winds are reduced by 1–2 m s −1 over Chennai (Figures 7g and 10c) in NRSCZ1 over USGS due to increased urbanization as well as increased roughness.…”

Impacts of Urbanization, Aerodynamic Roughness, and Land Surface Processes on the Extreme Heavy Rainfall Over Chennai, India

An increasing frequency of heavy rainfall events has been reported over various urban areas across the globe in recent times (e.g., Kistawal et al., 2020;Luong et al., 2020;Wang et al., 2018). Among several factors, land surface and boundary layer processes seem to strongly influence the development of convective storms, local weather systems, and extreme rainfall events (Pielke et al., 2011;Shem & Shepherd, 2009). Urbanization induced land use/land cover (LULC) change has been attributed as one of the causative factors for localized heavy rainfall events over cosmopolitan cities (
