目前這波冷氣團的最強勢力已經開始南下
地面強冷高壓1050百帕以上在蒙古,向東南推進,
高空500帕西風槽也到達對岸大陸沿海,24小時內就會通過台灣上空
緊接著就是西風槽後源源不絕的冷空氣大軍,
模式預報大致上認為0度線會到台灣北部 ,
其中甚至有預報-3度線也碰到台灣北部沿海
目前台北高空850帕溫度線6~7度線(台北目前13度)
可想而知這波冷空氣將會十分強勁(不靠輻射冷卻的威力),就即將可能出現的寒流等級
由於北方整個是冷高壓梯度,風向是北風帶下來加上高空短槽線波動帶上來的水氣
所以冷氣團造成的,北中南的溫度梯度特別明顯,但是降雨預報北中南都會出現。
還好明天沒事 XD
P.S 目前850帕高空的0度線跨過馬祖,馬祖海拔100米觀測到5.6度 .. 囧~~冷~~
(以上供參囉)
