对一些沙尘暴强度划分标准中存在问题的讨论

Discussion on Questions Existing in Some Partition Criterion of Sandstorm Intensity

研究发现,目前被我国一些学者采用的沙尘暴强度划分标准和气象观测规范中关于水平能见度观测记录的规定有明显差异,这个问题导致沙尘暴强度划分标准与50a气象能见度观测资料不匹配,从而引起资料统计上的混乱和强沙尘暴、特强沙尘暴分析上很容易出现的错误。为此,就这个问题进行了分析讨论。

We found that there are obvious differences existing in some partition criterion of sandstorm intensity adopted by some scholars and in the regulation of visibility observation records in Meteorology Observation Criterion. The differences resulting in that the partition criterion of sandstorm intensity doesn＇t match with the 50 year＇s meteorological visibility observation records, and easily cause confusion in records statistics and mistake in sandstorm grade analysis. The paper has analyzed and discussed these problems.
