Results indicate that there is a cold advection in the surface layer and a warmadvection at the higher level near the stationary front.
结果表明：静止锋附近的近地面层为冷平流，再往上为暖平流。

We must pay attention to the southern warm thermal advection as well as the northern cold thermal advection in the cold front shear type rainstorm process.
在该型暴雨的发生过程中，北部冷平流具有十分重要的作用，但南部暖平流的作用也不可忽视。

The result shown that the cold (warm) advection and convergence (divergence) in the velocity data were interrelated with the formation, maintenance, and disappearance of the snow-fall.
