wrf没看懂谁给解释下

xinshou6

1、E_WE: Number of velocity points in west-east direction  velocity points 是啥 2、metgrid Can process both isobaric and native vertical coordinate data sets  native vertical coordinate 是啥？ 3、A wind vector, shown in terms of its U and V components with respect to the source grid. with respect to the WRF simulation grid.  from source grid to earth grid and from earth grid to WRF grid。source  earth grid是正南北东西？source grid-source model 的xy是啥 grib自带吗？ simulation grid 是啥 不是xy吗 看着挺直的？4、Converter co-locates data tomass points 5、dv/dt=-a▷p-▷o+ F-2Ω*V, East-west, North-south, and vertical 咋推出来的 还有下面公式 还有后面数值方法有没有给我这种脑子看得懂的推导 最好中文书 我见过其他的finite difference method 但是我不会用所以导不出来 他F（u^n）是否简写了 6、numerical filters 、 acoustic step、Energy-containing deep convective updraft scale 7、chem里emission是什么具体格式 怎么作用进去的 为啥要插值 看了说明书跟程序很蒙
----------
physical modes of meteorological importance, such as Rossby waves, gravity waves, or simple advection, are often of much lower frequency than the highest-frequency modes admitted by the equations, such as Lamb waves and acoustic modes.
Rossby waves:

atmospheric Rossby waves form primarily as a result of the Earth's geography. Rossby waves help transfer heat from the tropics toward the poles and cold air toward the tropics in an attempt to return atmosphere to balance. They also help locate the jet stream and mark out the track of surface low pressure systems.兰姆波 因物体两平行表面所限而形成的纵波与横波组合的波，它在整个物体内传播，质点作椭圆轨迹运动。板波的一种，区分于SH波。
兰姆波又分为对称型(S型)和非对称型(A型.对称型(S波，扩展波)兰姆波的特点是薄板中心质点作纵向振动，上下表面质点作椭圆运动、振动相位相反并对称于中心。非对称型(A型，弯曲波)兰姆波特点是薄板中心质点作横向振动，上下表面质点作椭圆运动、相位相同，不对称。
声波模式 正向反射回来负的？
