对机载霜点湿度计现场测量卷云内水汽资料进行了分析。这些数据是在南半球和北半球中纬度地区进行的两次实地考察中获得的。在所调查的卷云内部有多次出现冰过饱和的情况，其中南半球出现的频率较高。两个半球的湿度数据差异的来源尚不清楚，推测这些差异可能与不同的污染水平有关。推导出卷云内部相对湿度的分布规律。
Water vapour data inside cirrus clouds from in‐situ measurements with an aircraft‐borne frost‐point hygrometer are analysed. These data have been obtained during two field campaigns, performed in the Southern and Northern hemisphere mid latitudes. There were many occurrences of ice supersaturation inside the investigated cirrus, with a higher frequency of occurrences in the Southern Hemisphere. The source of the differences in the humidity data from the two hemispheres is not clear, and it is speculated that these differences may be related to different levels of pollution. A distribution law for the relative humidity inside cirrus clouds is inferred.
