今年第24号台风“科罗旺”于9月7日停止编号。多部门会商研判本月预计有2至3个台风登陆或明显影响我国。
时至白露,暑气渐消。这个时节,除了华西秋雨,还要警惕秋台风。今年第24号台风“科罗旺”昨天(7日)已停止编号。根据日前多部门会商研判,本月预计有2至3个台风登陆或明显影响我国,数量较常年同期偏多,强度偏强。秋天的台风真的会比夏天的台风更厉害吗?
中国气象局原公共气象服务首席 朱定真:白露节气已经入秋了,所以实际上我们经常会谈到秋台风的危害往往比夏台风还要厉害。
一是白露时节太阳高度角向南落,我们都说台风的强度是跟海温相关的,在太阳高度角北半球向南落的过程中,其实南部的海洋是被太阳直射比较强烈的区域,所以海温条件是非常好的,所以这个时候生成的台风不亚于夏季台风的强度。
二是秋季冷空气开始相对活跃,台风和冷空气的结合,特别是台风残留云系和冷空气的结合,往往更容易爆发出比较强的降水,破坏性可能比夏台风还要厉害。
三是秋季正处于农时,我们的农业生产很多作物正是怕风雨的时候,所以从这几个方面综合来讲,其实秋台风影响的强度不亚于夏台风,但是它的破坏力或者时机,可能相对于夏台风来讲,对我们的影响更为显著。

Zhubei City, Hsinchu County, has completed the lighting improvement project of the Yilun Bridge on Douzaipu River. LED light and shadow design is used to enhance the nighttime visibility and aesthetic value of the bridge. Patented "Flower of Freedom" landscape lights are installed at both ends.
