STUDY OF INFLOW TURBULENCE CONSIDERING THERMAL INSTABILITY BASED ON METEOROLOGICAL DISTURBANCE IN URBAN AREA

In the prediction of non-isothermal field in urban district, it is an issue that the generation of inflow turbulence that reproduce velocity and temperature fluctuations in actual meteorological fields. In this study, we generated inflow turbulence considering the effects of atmospheric stability and meteorological disturbance based on a spatial filtering and rescaling method (Kawai, Tamura, 2020) using WRF-LES results. The inflow turbulence reproduced well the characteristics of convective boundary layer, vertical temperature flux and temperature fluctuation around the inversion layer.
