Abstract: The water vapor content of the weather system in the atmosphere has a great infuence on precipitation. Research shows
that the annual average water vapor content of the gas column from 500 to 1000 hPa from 2010 to 2017 at the southern foot of
Taihang Mountain is between and g/cm2, the difference between the peak and trough is g/cm2, and the average
precipitation efficiency is %. Precipitation efficiency is related to precipitation size and weather system. When precipitation
is 10–50 mm, precipitation efficiency increases with
