家裡念小學的小朋友對颱風很好奇,問他老爸:「這次颱風我們這(台北)會像上次(指蘇力
)颳很大的強風嗎?」
他老爸回:「不會,你看一下這個預測圖,這個圈圈就是暴風圈,被掃到的會有狂風暴雨
的機會,但是在圈圈外的通常只會下雨,風有一點點,但不會刮啦,也不會放假,尤其你
看,這離我們這麼遠,風怎麼會吹得上來?」
「那甚麼颱風會讓台北颳大風?」
「強烈颱風,從西北方向從宜蘭上面穿過去,風就會從淡水河往陸地上吹,就會很強,其
他方向因為中央山脈或雪山山脈會擋住,台北是盆地,四周都有山擋住,吹不到甚麼風的
。」
感覺回答就是有似是而非教錯小孩的樣子(但我也好不到哪去,就也不便多說)
不過這樣的認知好像很多一般民眾真的都如此覺得...
尤其是第一點,印象中像天兔這種路徑的颱風,扣掉東北季風共伴效應的因素外,對北部
帶來風力的影響應該是不會很大的?不知道有沒有專業大大可以解釋一下?
