By using five different kinds of land surface parameterization schemes (SLAB

Noah

RUC

PleimXiu and SSiB) in WRF model and combining with the latest land cover data Globcover2009

the tests about boundary layer structural features were simulated in the Pearl River delta region from 28 to 29 April 2014. Meteorological parameters

including weed speed at 10m

temperature at 2 m

vertical profile of wind speed and temperature

were evaluated and compared to the observations from 18 surface weather stations and 1 sounding station in the research area. The results show that: ①compared with the USGS land use data

distribution of land use classes in Globcover2009 is more consistent with the current actual type of surface. The simulation precision of wind speed and temperature near the surface can be effectively improved by updating the land use data; ②WRF model can simulate the diurnal variations of surface meteorological parameters basically. Due to the lowly coastal terrain

the simulations of wind speed at 10m are more easily overestimated from these five schemes

while the results of temperature at 2m are underestimated to various degrees. Among them

the simulation result of wind speed in SLAB scheme is the best and the simulated temperature in Noah scheme is more accurate than others

the error between simulations and observations in SSiB scheme is the biggest. ③The vertical profiles of wind speed and temperature obtained by Noah

SLAB

RUC and PleimXiu are almost the same in variation trend and these simulations are in line with the actual situation. The characteristics of atmospheric boundary layer from SSiB scheme are not obvious for the reason that vertical stratification near the ground is set too sparsely.
