The Chinese also launched weather balloons near their theodolites to measure atmospheric temperature and pressure changes to better estimate refraction errors.
中国还在经纬仪附近发射了气象气球来测量大气温度和压力变化，以更好地估计折射误差。

Atmosphericpressure, which changes with the phases of the moon, can also affect the taste.
随月球运行周期的改变而改变的大气压力也会影响到口感。

As the vapor condenses into rain, the local atmosphericpressure drops.
