摘要: In this work, the impact of land surface physics in simulating sea and breeze circulation along south east coast India near Kalpakkam is studied using Weather Research Forecasting (WRF) model for emergency response application. Simulations were conducted with three different models (LSMs)—5-Layer soil thermal diffusion scheme (5-Layer), Noah (Noah) Multi-Physics (Noah-MP) days summer southwest monsoon. Observations from meteorological towers, automated weather stations, sonic anemometers GPS Radiosonde profiles used comparison. Results indicate that Noah-MP followed by schemes produce more realistic simulations terms intensity, onset time, duration, horizontal vertical extents most cases compared to 5-Layer scheme. grossly overestimated air temperature, heat flux boundary layer height relative schemes. The better represented land-surface feedback skin temperature energy fluxes leading characteristics.
