南方财经记者郑玮 实习生王硕 广州报道 暴雨又要来了。 据"广东天气"9月4日消息，未来48小时内，南海到菲律宾以东海域可能有热带低压生成。受此影响，9 月7日至10日，广州可能迎来雷阵雨转大到暴雨。 在近一个月接连遭遇多场强降雨后，广州将再次进入"暴雨模式"。 "这是几年来最大一场雨了。"回忆起8月初的那场暴雨，广州市从化区良口镇达溪村书记陈常东仍印象 深刻。这场由"陆地台风"低涡系统带来的本世纪第5强暴雨，最大过程雨量达到622.6mm，短时强降水 覆盖率达到91.1%，打破了从化区24小时雨量极值。 暴雨带来的影响是直观的。8月5日早晨，达溪村山洪暴起，裹挟着泥沙，冲毁了河岸，淹没了房屋和田 地，通讯也短暂中断。幸运的是，此时陈常东已根据不断发来的山洪预警信息，通知沿河居住的45名群 众全部转移至安全地带，全村无人在这场世纪暴雨中伤亡。 这仅是近年来广州遭遇的多次极端天气之一。台风、暴雨、冰雹、龙卷风、极端高温……广州市气候中 心公布数据显示，广州近十年遭遇的极端天气事件频率较上个十年有所增多，尤其是极端暴雨和极端高 温事件。 不仅仅是广州，气候变化带来的影响是全球性的。联合国政府间气候变化专门委员会（ ...
