引言如下:

The plot-feasibility condition that descending tropospheric air would be cold, because it was descending too fast to warm up, is physically impossible. Bringing air downward means the air must be compressed from a very low pressure to a much higher pressure. By the ideal gas law, the temperature of the air must increase. Furthermore, the potential temperature of tropospheric air is higher, not lower, than the temperature of surface air. If brought to the surface, it would have a higher temperature than the surface air.

結論是 不合 物理邏輯 !!
