topographic forcing
Examples
- Convective and shear instability can provide the wave energy . during the initial and merger stages , the convective and mgws interact with each other constructively
( 3 )太行山地形强迫和对流是本次mgws产生的重要机制，对流和切变不稳定为重力波的加强和维持提供能量来源。 - ( 2 ) increasing of wind is mainly induced by shf and affecting of lhf is very little . ( 3 ) effect of terrain increases ground rough and tonsure of terrain press and fiction correspond enhance frictional damp effect
( 3 )地形作用相当于增加了地面粗糙度，地形压力梯度项与摩擦项地叠加，相当于使摩擦阻尼作用增大，地形强迫作用使下边界层从上至下风速减小，风向向左偏转。 - The first can be called a typical huabei mcs , whose initial convections are arisen by terrain forced climb ; the second initial convections are arisen by boundary convergence lines in the afternoon , meantime the lower level cold air from huabei plain also contributes to their formation
第1次是比较典型的华北mcc中尺度对流复合体过程，它是由地形强迫抬升触发了初始对流。第2次初始对流是由午后的边界层辐合线触发的，从华北平原南下的浅薄冷空气也起了重要作用。
