本文测量了科罗拉多州东北部、俄克拉何马州中部和艾伯塔省中部三个地理区域的冰雹形状因子，即冰雹的长轴和短轴之比(m‘/m)。结果表明，随着尺寸的增大，球度总体呈下降趋势，且不同地区的球度有所不同。这一结果与利用偏振的雷达技术进行冰雹遥感有关。
Abstract The shape factor of hailstones, defined as the ratio of their long and short axes (m′/m), has been measured for hailstones from three geographical areas: northeastern Colorado, central Oklahoma and central Alberta. The results show a general tendency toward decreasing sphericity with increasing size and are different for different areas. The results are relevant to remote hail sensing by radar techniques utilizing polarization.
