下坡风

4.28过程由于太行山地形影响而产生的下坡风与西南暖湿气流相汇合，形成中尺度辐合线，触发了不稳定能量的释放，产生对流并由中尺度辐合线组织成飑线。

For the 4.28 process , the mesoscale convergence line , which is formed by downslope wind from the Taihang mountains converging with the southwest warm humid wind , releases the Convective Available Potential Energy , initiates the convection and organizes the convective cells into squall line .

持续不断的下坡风造成了沙丘的堆积。而沙丘又导致一片塔那河流沿向的云杉树林濒临死亡。

Relentless downhill [ wind ] currents deposited dunes that choked out a spruce forest along the Tana River .

研究结果表明：（1）北京区域夏季边界层风场受西北特殊地形的影响，夜间低层大气流场常表现为由北向南的下坡风，白天逐渐转为由南往北的上坡风。

Such results are gotten : ( 1 ) Due to the unique topography the wind of Beijing area during the day time is southern anabatic wind and in the night is northern katabatic wind in summer .
