即時小觀:48小時候逼近台灣第一波寒潮爆發
目前模式預報來看,極可能成為台灣第一波寒潮爆發,
位於東亞北部的高空冷渦旋的橫槽線在蒙古/西伯利亞積蓄大量冷空氣,
蒙古地區氣溫下將,氣壓上升,冷高壓強度已達1040百帕以上,
目前冷空氣已經積蓄到一定的強度,推動冷渦開始往東移動,
橫槽轉為東北西南向,冷高壓跟著往東南移動,
整個西風槽線壓到台灣,冷高壓中心整個從蒙古往東南移往華北,
由於西風槽從東亞沿岸直接壓下來,對應強冷空氣直接從黃海、東海到台灣,
因此強冷空氣受地形阻擋較小,加上這次西風槽壓到台灣北端,
因此台灣降溫很明顯,48小時內溫度急凍逼近寒流甚至偷渡達寒流。
可以說是一次強烈冷氣團爆發。
需要立即保暖禦寒
(以上供參囉)
