广州20天降水总量相当于54.5万个8道标准游泳池|广州|降水_新闻资讯
原标题：穗20天雨量等于680个白云湖
南都讯 回看广州4月份以来天气，雨神就不曾离开广州，大雨、中雨、小雨来回穿梭于羊城的天空，雷阵雨、8-10级大风也时不时地半路杀出。据统计，4月1日至20日期间，广州20天的降水总量超过13.6亿立方米，可填满680个白云湖，相当于54.5万个8道标准游泳池的水量！
雨量比常年同期多七成
●20天降雨量指4月1日-20日；常年同期是指1981-2010年4月1日-20日平均降雨量
解读：根据广州入汛标准：每年3月1日起，全市累计有一半或以上监测站点出现日降水量≥38.0毫米（大到暴雨级别降水）降水，则将该日作为本市汛期开始日期。广州今年于3月21日开汛，比常年平均（4月5日）偏早足足15天。
广州雨量为历史同期第7大值
广州历史同期最高雨量：
1987年4月1日-20日 雨量274.5毫米
解读：广州雨水哗哗，4月1日- 20日期间录得全市平均雨量为183.3毫米，较常年同期偏多70%，为历史同期第7大值。
广州平均每天出现118次闪电
●统计时间：4月1日-4月20日
解读：4月底，雷雨仍不肯放过我大羊城。预计，4月下旬华南暖湿气流强盛，加之高空低槽频繁影响，下旬广东强降水和强对流天气频繁，部分市县伴有暴雨和8级-10级雷雨大风等天气。
广州哪个区雨水最多
各区4月1日-20日总雨量（毫米）
解读：各区雨量为134.7~270.8毫米，其中从化最多，越秀最少。4月1日- 20日共20天中，4日、10日、12日、13日和18日雨势较大。
这些雨量相当于680个白云湖
●广州最大人工湖白云湖容量为200万立方米；一个8道标准游泳池容量为2500立方米
解读：雨水多，原来是厄尔尼诺惹的祸！受厄尔尼诺影响，西太副高明显偏强，偏西、偏南，其西南侧偏南气流强盛，广东水汽输送充足。配合中高纬度冷空气、东移南支槽和等天气系统的共同影响，所以这段时间的雨下得很豪放嘛。
你的城市雨水多吗？
4月1日-20日广东各市（县）累计降雨量
雨量>250毫米的市（县）：翁源、惠来、始兴、大埔、平远、汕尾、南雄、英德、乳源、从化、海丰、河源、曲江、陆丰、佛冈、连南、连山、仁化、连平、龙门、和平
雨量<50毫米的市（县）：雷州、徐闻、吴川、遂溪、化州、湛江、电白、茂名、廉江
广州24小时降雨量对比（3月21日-4月21日，单位：毫米）
总雨量最大：0点- 1点（相当于9.8万个标准游泳池）
一个月内4个小时区间有暴雨，其中三个小时区间是在凌晨
解读：较明显的降水出现在早晨1次、上午至中午3次、中午至下午2次、上午至下午3次、夜间1次。广州市区暴雨黄色预警信号共发布3次，分别在4月4日14：02、4月17日20：16、4月20日16：07，可见暴雨预警信号主要在午后到上半夜时间段内发布。
气象专家介绍，陆地上夏季的午后降水峰值较为常见，这通常是太阳辐射加热的日变化，致使午后温度较高，暖空气上升造成不稳定，导致降水的发生。这类降水多为局地性降水，持续时间通常较短。
