1) Concavity(convex) of hail frequency
降雹频数的凹(凸)度
2) Concavo-convex parameter
凹凸度参数
3) hailfall times
降雹次数
1.
The results showed that: the hailfall times are increasing;the hailfall times in the northern are more than those in the southern;the hailfall times of the mountainous area are more than those of the plain;the hailfall times in eastern are more than those in western part;the increased range is bigger in western than that in eastern.
统计分析了位于天山南麓的阿克苏地区1998—2008年的降雹资料,揭示了近年来地区降雹的时空分布特征以及冰雹云活动的主要路径,结果显示:该地区降雹分布为北部多、南部少,山区多、平原少;该地区降雹次数呈线性增加趋势,东部降雹次数多于西部、西部降雹次数增幅大于东部;由于冰雹云路径复杂多变,冰雹防御的重点在主要冰雹云路径和重点农作物区。
4) Two climate maps of different hail frequencies
两种降雹频数气候图
