A thunderstorm happened in Tai Lake region in August 2010, which is used to test the impact of two different land surface models(Noah and RUC schemes) coupled with the weather research forecasting(WRF) model on simulation of the thunderstorm.The short-range weather simulation is performed for 48 h.The simulated results are compared with the observed rainfall, surface temperature and wind speed at Yixing and Wuxian stations.Results show that Noah scheme has a fairly better performance than RUC scheme, and the simulated thunderstorm is sensitive to the chosen land surface model(LSM).The different LSMs can lead to the differences of location, time and intensity of thunderstorm, and the maximum of daily precipitation difference between the two schemes can be above 40 mm.Comparison of the simulated results shows that the convection development delays for 2 h in RUC experiment relative to Noah experiment, which indicates that the land surface representation has a prominent feedback on the mesoscale convection of thunderstorm.Different land surface models can lead to different thermal and dynamic effects, which influence the development of thunderstorm and result in differences of convection initialization, development and maintenance between the two WRF runs with different LSMs.Due to parameterization difference of vegetation properties for different land use categories in the two land surface models, Noah scheme describes the characteristics of underlying surface reasonably better than RUC scheme, especially the urban land use category, which can improve the ability of WRF run with Noah LSM to simulate the thunderstorm.
