狭管效应

模拟结果得到了一些流场的特征，如涡旋、狭管效应、垂直回流涡旋等。

Some characteristic flows , such as the flow eddy , channeling flow , and vertical recirculation vortex were simulated .

最后还对渤海东北大风狭管效应等问题进行了讨论。

A discussion is also made of the " narrow pipe effect " of the northeast gale in the Bohai Sea .

设计的几种地形改变的方案实验结果表明：加高地形高度有利于诱生低压，也有利于加大狭管效应；

Experiments of changing terrain show that the heightened terrain is propitious to impressed depression and enhances canalization of Taiwan Strait .

结果表明，河西走廊连通器的虹吸效应主要是传输各种物质和能量，连通器效应是产生垂直运动、激发重力波和产生翘翘板现象，而狭管效应主要是增强风速。

The results indicate that : siphon effect mainly supplies the matter and energy transformations , connected vessels effect is to start vertical movement 、 excitated gravity wave probably and produce phenomena of teetertotter , while narrow pipe effect is to increase velocity .
