This study presented airborne measurements of ice particle properties in three stratiform precipitating clouds over northern China.

By using horizontal observations at selected altitudes, the distributions of ice water content (IWC), particle habits, and particle size spectrum parameters were investigated.

The cloud cases were characterized by high IWC values due to the existence of embedded convective cells.

Liquid water contents were rather low with the maxima of less than 0.3 g m−3 and the general values of less than 0.1 g m−3.

The occurrence of large dendritic crystals as well as rimed capped columns and branched crystals indicated that ice seeding from the above cloud layer (6 km altitude or above) contributed significantly to both high ice crystal number concentrations and IWCs.

Horizontal observations at selected levels suggested the general decreasing trend of IWC with decreasing temperature only in part of the cloud layers but not throughout the cold layer of the multilayered stratiform clouds.

Both exponential and gamma functions were used to characterize the particle size spectrum parameters.

The slope parameter values of exponential distributions were primarily in the range of 103–104 m−1.

In comparison, slope values of the gamma distribution fits spanned more and a relationship was found between the dispersion and slope values.
