为了察看利用单站降雹频数F_s和区域降雹频数F_a制作的两种气候图的频数分布是否一致?我们绘制了该两种气候图,并进行了初步分析。结果表明,在引进了降雹频数凹凸度R,又引进了空间一致性表达式后,在两种降雹频数气候图上,它们高(低)值分布有84%的格点相一致。

Usually,there are two kinds of hail frequency data: One is in the station(F_s);another,in a area(F_a).Are their climate distribution map the same? to answer the question,the two climate maps of hail frequency were made with F_s and F_a.Some intercomparisons with each other were done.Firstly concavity(R) in hail frequency was introduced in order to watch the agreement in relative distribution of hail frequency(F) in two climate maps(as F is relative large,R<ε;relative less,R>+ε;saddle).Secondly,spatial agreement was also calculated used formula introduced.Results indicated(at least) 84% of grid numbers(distribution of high or low value) is agreement in two climate maps.
