摘　　要：雹云识别是一个多参数的模式识别问题,应用物元可拓思想将单参数雹云识别的不相容性转化为相容性问题。在与成都地区雹云识别的物元可拓模型进行对比后,根据低纬高原地形及气候特点,通过适当增加参数,构造完成低纬高原雹云识别的物元可拓模型,以此进行雹云识别,准确率达86%以上。Hail cloud recognition is a pattern recognition problem of multi-parameter. The recognition result of hail cloud based on single parameter is always non-compatible. The basic thinking of matter elements and extension set is used for changing the non-compatible problem into compatible problem. The comparison study results show that the accuracy of hail cloud recognition by this method is over 86%.
