时间平均流 meaning in Chinese

time-mean flow

On the other hand , it is indicated that the velocity field consists of a depth - independent inertial oscillation and a time - mean shear flow , which can be obtained by subtracting the inertial oscillations time mean in one inertial period . the hodograph of the velocity vector of time - mean flow at the different depths consists of a ekman spiral , and the surface velocity is 30 . 3 ? to the right of the wind
一维模式的流场结果表明，混合层中的流场是由惯性波动与时间平均流两部分叠加而成，且通过时间平均消去惯性波动后得到平均流，其不同深度的流速矢量构成一ekman螺旋，表层流速矢量相对风向右偏了30 . 3 ’ 。
