提利用地基微波辐射计观测资料，对两次冰雹过程进行观测分析。结果表明：中低层暖湿气流输送、中层干冷空气侵入，在0～10 km形成“上干、下湿”2层垂直分布结构。低层的感热和潜热随上升气流向上输送，2～3 km 层明显增温，0、-5和-20℃层略微上升。同时，低层水汽也随上升气流向上输送，降雹前大气液态水总含量（ILW，下同）和大气水汽总含量（I WV ，下同）及过冷水含量快速增长。水汽经过冷层后，冰晶增多增大。当冰晶增大落入0℃以上区融化层时，冰晶融化导致液态水增加，一部分形成冰雹或地面降水，导致降雹之后ILW、IWV 及0℃以下液态水含量减小。上述结论对冰雹的预警有一定指示意义。

Using ground-based microwave radiometer observation data,two hailstorm cases that happened in Xianning of Hubei Province on 26 February 2009 and 12 April 2010 are analyzed.The results show that low-level warm air transportation and mid-level dry cold air intrusion contributes to the “upper dry and lower wet”2-layer vertical structure of 0-10 km relative humidity.The updraft transports upward sensi-ble heat and latent heat of the low level,resulting in the significant warming of 2-3 km layer,and the slight rising of 0,-5 and -20℃ layers.As the low-level moisture is rising up,ILW,IWV and super-cooled water grow rapidly before the hail.After the wet vapor goes through the cold layer,the ice crystals increase.When the ice crystals increase and fall into the area above 0℃ melting layer,the ice crystals are melted,leading to an increase in liquid water,and part of the water becomes hails or surface precipitation, so that the ILW,IWV and liquid water content below 0℃ decrease after hails.The above conclusion is of some significance to the early warning of hails.
