He felt dust fronts, billowings, mixings of turbulence, an occasional vortex.

他感觉到尘埃的锋面、滚滚的浪潮、湍流的混合，以及偶尔出现的。

Once released from the surface, dust particles are raised to higher levels of the troposphere by turbulent mixing and convective updrafts.

一旦从地释放出来， 尘埃颗粒就湍流混合和对流上升气流上升到对流层的更高水平。

Without a surface layer of ice, will wind and waves cause so much turbulence and mixing that warm deep salt water rises to the surface and prevents even winter ice?

如果没有层冰，风和波浪是否引起如此大的湍流和混合，以至于温暖的深盐水上升到面，甚至阻止冬季结冰？
