进入7月下旬，北方多地开启了多雨模式，河北、内蒙古多地出现破纪录的大暴雨或特大暴雨……一年 一度的"七下八上"防汛关键期又到了。什么"七下八上"，不是"七上八下"吗？是搞错了吗？一起来听它 自己的解释吧~ 大家好，我就是传说中的"七下八上"。要说我和"七上八下"有什么关系，那可能是我的到来意味着华 北、东北等地主雨季开启，进入一年中降雨最集中的日子，让大家心里有点"七上八下"吧。 我一般出现在每年的7月下旬到8月上旬，这也是我名字的由来，按照雨季防汛标准，我的在岗时间段也 可以延伸到7月下半月到8月上半月。在岗期间，我铆足了劲地提升北方的降雨指标，基本上我一个月的 雨量就能占全年的三分之一。靠我的实力，华北、东北地区，甚至黄淮以及陕、甘、宁部分地区，都将 体验到一年中最集中的雨。 可别小瞧了这雨，我虽然身在北方，但造雨能力可不比南方雨季弱，我最擅长的技能就是暴雨产出，并 附赠雷暴大风等强对流套餐。 从1991年至2020年的历史大数据可以看到，我管辖区域内省会级城市7至8月的降雨量几乎可以占到全年 总雨量的一半。比如，北京、石家庄、济南、天津、沈阳5市两个月降雨量占全年的比例都在50%以 上，也就是一年中一半 ...
