据统计，包括暴雨洪涝、连阴雨、干旱在内的降水异常灾害是沾化冬枣主产区最严重的气象灾害，因此降水条件成为主产区最易产生不利影响的气象要素。为了解掌握沾化冬枣的降水适应性，对沾化冬枣产业化发展以来降水异常灾害发生情况进行统计，并结合主产区唯一适用的沾化国家一般气象站降水观测资料，系统总结了沾化冬枣适宜降水条件特征，再结合各降水异常灾害受灾时段的降水情况，进一步分析总结对沾化冬枣不利的降水条件，估计部分致灾降水条件。

According to statistics, the most serious meteorological disasters of Zhanhua winter jujube producing areas is precipitation anomaly disaster, including rainstorm, flood, drought, so precipitation conditions become meteorological factors which caused adverse effect the most easily in the winter jujube producing areas. In order to understand the precipitation adaptability of Zhanhua winter jujube, the precipitation anomaly disaster had been counted since winter jujube brought about industrialization, combined with the observed data of precipitation in Zhanhua national meteorological station only. The Zhanhua winter jujube suitable precipitation characteristics was summarized, combined with the precipitation anomalies in precipitation disaster time, precipitation conditions adverse to the Zhanhua winter jujube were analyzed further. Causing disaster of precipitation conditions was estimated.
