Positive pressure area的意思|示意

The precipitation area has a good relationships with low level positive vorticity, water vapor, pressure energy, moist enthalpy, potential vorticity etc.

诊断分析中发现暴雨落区和低层正涡度、水汽、压能、湿焓、位涡等有很好的对应关系。

Due to the influence of radial positive pressure gradient, low-energy gas moves along trailing area to hub. That causes rapid dissipation and weakening of downstream passage vortex.

在叶栅下游，由于径向正压梯度的影响，低能气体沿尾流区向轮毂输运，引起下通道涡的迅速消散与衰减。
