PV banners generate over the leeside of the DM with a maximal intensity of ～1.5 PVU, and extend more than 100 km downstream, while the width varies from several to tens of kilometers, which contrasts with the half-width of the peaks along the ridge of the DM. Wave breaking occurs near the leeside surface of the DM, and leads to a strong PV generation. Combining with the PV generation, due to the friction and the flow splitting upstream, the PV is advected downstream, and then forms the PV banners over the DM. The PV banners are sensitive to the model resolution, Coriolis force, friction, subgrid turbulent mixing, stratification, the upstream wind speed and wind direction. The negative PV banners have a more compact connection with the low level turbulent kinetic energy. The PV banners are built up by the baroclinic and barotropic components. The barotropic-associated PV can identify the distribution of the PV banners, while the baroclinic one only has important contributions on the flanks and on the leeside near the topography. PV fluxes are diagnosed to investigate the influence of friction on the PV banners. Similar patterns are found between the total PV flux and the advective PV flux, except near the surface and inside the dipole of the PV banners, where the nonadvective PV flux associated with the friction has a net negative contribution.展开更多

The authors studied some excellent square designs in Inner Mongolia, China and even overseas countries, summarized the standards of "best urban squares" in vision, culture, craft, human-concerned design, science and technology, and then applied such standards in the landscape design of Central Plaza in Zhungeer Banner. Through analyzing surrounding environment and constructions, design schemes with regional and cultural features were created to provide references for designing better green square landscapes which can demonstrate local cultural context and regional cultures, are moderate in size, diversified in spatial form and closely integrated with the social life of citizens.展开更多
