warm advection

The results showed that the development and strengthen of instability stratification in Shenyang area resulted from warm advection of Mongolia cyclone foreside, large positive vorticity region and positive vorticity advection.

结果表明：蒙古气旋前部的暖平流、大范围正涡度区和正涡度平流导致了我国沈阳地区不稳定层结的建立和加强；

The qualitative identification methods of Doppler radar velocity PPI pictures are introduced. The related image features of convective rainfall clouds are analyzed: ① the zero-velocity lines in the wind field related to large-scale convergence or divergence in combination with cold or warm advection;

介绍了多普勒雷达速度PPI产品图像定性识别方法，分析了与对流性降水云体有关的图像特征：①冷暖平流与大尺度辐合辐散运动相结合的零速度线；

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。

Simulating study on the inducing mechanism of the heat structure variation of the water surface thin layer ── effect of air cool/ warm advection

水面薄层热结构变化诱发机制的模拟研究&空气冷/暖平流效应

The results show that over the Huanghai Sea and the East China Sea area there is warm and humid air advection from south sea area in the near surface atmosphere in both day and night in May and June.

分析结果表明，黄海、东海海域近海面大气层于5月和6月无论白天和夜间都有来自南方海域的暖湿空气的平流输送。

There is strong cool advection below highs of 200 m, while the weak warm advection between the heights of 250 m and 400 m. The heat advection have significantly influence on the temperature and stratification of boundary layer;

夜间200m高度以下有较强的冷平流，在250～400m高度有较弱的暖平流，冷暖温度平流对测点上空边界层温度和层结变化有显著影响；
