不同陆面方案对珠三角春季晴天边界层特征模拟效果的影响
Effect of Different Land Surface Schemes on Simulation of Characteristics of Spring Clear Day Boundary Layer in Pearl River Delta Region
摘要
Abstract
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 201 4.Meteorological parameters,including weed speed at 1 0m,temperature at 2 m,vertical pro-file of wind speed and temperature,were evaluated and compared to the observations from 1 8 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 ef-fectively 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 1 0m 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.关键词
