The seasonal reversal of wind field from the upper troposphere to the stratosphere is as pronounced as in the middle and lower troposphere.

The dry PV field in the lower troposphere shows that the coupling of the dense PV isoline zone and the wind shear was formed in the storm area.

In the convectively heating region latent heat release causes a heating peak in the upper troposphere and a moisture sink in the lower troposphere.

在对流加热区，大量的潜热释放形成深厚的热源和水汽汇，热源峰值出现在上部对流层，水汽汇峰值出现在下部对流层；

The sums required to correct the lower-troposphere temperatures are so byzantine that more holes may yet be found.

This alters the calculation needed to derive the lower-troposphere temperature.

Ozone in the lower atmosphere (troposphere) is regarded as a serious pollutant that can cause respiratory problems, and even damage masonry and agricultural crops.
