%X Sensitive tests are done to research the impact of initial soil moisture to the forecast of boundary layer variables,using T213L31,NMC global medium-term numerical prediction model system.The tests show the correction of the initial soil moisture is very important,its change lead to the change of sensible heat flux,latent heat flux,skin temperature and 2 m temperature those were calculated by the model.When using more reliable initial soil moisture that is similar to observation,the boundary layer variables,such as 2 m temperature,are more correct.Using of weighted average of the specific soil moisture from ECWMF and forecasting soil moisture as initial soil moisture,the error of 2 m temperature become smaller than before.
