较暖空气向较冷空气方向输送(空气由高温区流向低温区)称为暖平流。 暖空气沿水平方向向广大较冷区域流动的现象。它是空气水平运动的种类之一。当风随高度作顺时针旋转时,则有暖平流出现。且平流的强弱,可进行定量计算。暖平流是天气变化的影响因素之一。
强烈的冷、暖平流空间配置使大风、沙尘暴和降温更为剧烈。
The space allocation of intense cold, worm advections intensify the strong wind, sandstorm and temperature decreasing.
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。
Results indicate that there is a cold advection in the surface layer and a warm advection at the higher level near the stationary front.
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。
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.
