简介：在华东和NCEP/NCAR每天全球的期末考试从212个车站基于每日的降水数据在从2000～2010的6月和7月的分析数据，frontogenesis的climatological特征和相关发行量被分析了。结果证明那frontogenesis功能在华东非一致地散布。运动学的frontogenesis的不同学期显示出frontogenesis的不同紧张和分布。从不同运动学的frontogenesis学期综合的最强壮的frontogenesis在Jianghuai区域被观察。Frontogenesis事件作为每被分开成四种类型不同砍并且沿着在850hPa的强壮的frontogenesis乐队的水平风的集中类型。四种类型包括温暖砍类型，冷砍类型(与二种子类型)，西方风集中类型，和东方风集中打字。在不同frontogenesis类型的事件在过去的十年与不同频率发生。温暖砍类型最经常发生。frontogenesis的不同类型有特殊水平、垂直的结构。强壮的frontogenesis与se平行的340-K轮廓被展示到正面的地区在垂直。在气旋或反气旋，风集中，以及垂直发行量结构的转移地点和力量表明的改变的大规模发行量模式与frontogenesis的不同类型被联系。而且，在frontogenesis和降水之间的强壮的积极关联被发现，即，越强壮frontogenesis，有越多猛冲。每日的降水与有关温暖砍类型frontogenesis最大，并且经常与强壮的frontogenesis带与一样的取向发生在正面的地区内。第二最大的每日的猛冲与寒冷发生砍类型frontogenesis，和相关降雨通常被观察到正面的地区的南方，与延长的雨带向东北。与西方风集中类型frontogenesis有关的降水是第三最大，主要在正面的地区的南方发生。
