又称垂直风切变，风的垂直方向上的变化，通常为850hPa和200hPa风速只差。公式为： ， 其中u200和u850分别表示200hPa和850hPa等压面上的纬向风速；v200和v850分别表示200hPa和850hPa等压面上的经向风速。
上新世早期的大气环流被减弱，因此垂直风切变减小，助长了热带气旋的发展。
Tthe early Pliocene had a weakened atmospheric circulation, and therefore, reduced vertical wind shear, which is favorable for tropical cyclone growth.
文中指出垂直风切变及其变化与温度平流的存在是紧密相关的。
It is pointed out that vertical wind shear and its change are closely correlated with the temperature advection.
飑线的产生经常与不稳定能量和垂直风切变相联系。
The occurrence of squall lines is frequently associated with instability energy and vertical wind shear.
