海棠來了,但是陸地無害
還以為24W要被JMA放生了

技術上從溫帶氣旋直接轉為颱風因此沒寫自熱低升格
2005海棠:這是什麼?
哈哈笑死突然升格
小J最愛撿副熱帶野孩子
其實2005海棠也是冷渦底下長出來的
2005年海棠也是 先南落 這種路徑的前輩了
基本就是走一個大U字型的2005海棠
海棠好像只有登陸台灣的那個強而已,其他都頗弱
2017海棠也有登陸台灣
其實24W當初就是在21W的東北方共旋,後來21W先一步
被西風槽牽引加速離開後,24W在高緯陷入滯留。
性質也從帶有副熱帶性質的低壓,逐漸正壓化。
總之,這一波9月底10月初的大量擾動,最終有6個擾動
目前其中三個被JMA升格為颱風,四個有JTWC正式編碼
忘了講,其實24W也是從中低緯生成,只是吞了冷渦,
又當初從21W的北方繞過21W,吃太多乾冷空氣,才會使
24W在生成之初就有很嚴重的副熱帶性質,對流不足。
不是吞了冷渦,而是它就在冷渦下方生成
這種高空有另一個冷低壓的低層暖心系統,就是副熱帶
最早JTWC是「高層低壓系統」稱呼91W,後來低層才有
