The effect of urbanization pattern on the interaction of the atmospheric boundary layer with the mesoscale weather is investigated over a tropical coastal environment. For this purpose, two cases are considered during the inter-monsoon period under highly convective and low wind conditions. In order to simulate these cases,the Weather Research and Forecasting (WRF) model is run at 300 m resolution. The urban effects are incorporated in the model through the coupling of a single-layer urban canopy model and Noah land-surface model within WRF. Significant impacts of the pattern of urbanization on the mesoscale weather are identified and the reasons for such strong influence are elucidated from diagnostics of surface temperature and heat flux disturbances arising from urban landuse.
