The new generation mesoscale model WRF is used to simulate a typical thunderstorm process in Ningbo area on 24 June 2006,and the impacts of land surface parameterization schemes(Noah and RUC) on numerical simulation of the thunderstorm process are tested.The results show that,for surface thermodynamic field before the thunderstorm happened,the simulated results with Noah scheme are more close to the observations.However,with RUC scheme,the simulated results do not reflect the diversity of underlying surface coverage and the impacts of city underlying surface,and the difference between rural and urban areas is not obvious.The start and development processes simulated by Noah scheme are more reasonable,and the results simulated by RUC scheme describe the key stages in the evolution process of thunderstorm well,such as three merging processes.Because the considered factors and physical process parameterizations are different,the strength and center of accumulated precipitation simulated by Noah scheme are more consistent with the observations than those simulated by RUC scheme.The duration of thunderstorm is strongly sensitive to land surface process parameterization,and both durations simulated by the two schemes are longer than actual duration of the thunderstorm to different degree.Whatever the land cover category in Ningbo area,the sensible heat flux(latent heat flux) simulated by Noah scheme is greater than(less than) that simulated by RUC scheme during the day.
