vertical turbulent velocity scale 垂直湍流速度尺度
Mean velocity profile, turbulence intensity profile, integral scale and wind spectra are the most fundamental characteristics that describe the atmospheric turbulent boundary layer flow.
平均速度剖面，湍流度剖面，积分尺度和风谱是反映大气湍流边界层流动的四个最基本的因素。
Results as the velocity shear increases to a certain extent, the small scale disturbances will exhibit chaotic behavior, which leads to the production of turbulent spots in local high shear regions.
结果在速度剪切度增大到一定程度时，将会出现小尺度扰动的混沌行为，它导致局部高剪切区中湍斑的产生。
It can make full use of favourable ignition conditions such as high temperatures in reflow region and low velocity as well as high turbulent scale.
