天氣小觀:強烈冷氣團挑戰寒流,平地寒氣逼人,高山飛雪連天,倒數3天
四季月份以2月、3月、4月春天,或3月、4月、5月春天;
但在全球暖化異常下,
結合到台灣氣候來看,
2、3、4月:冷空氣頻頻就當冬天,
5、6、7月:常常下雨就當春天,
8、9、10月:才開始追風就當夏天,
11、12、1月:常常不冷就當秋天。
要是以後都這種四季月份,這樣對嗎,真是嚇鼠人了。
最新長期模式報出3月北極渦旋偏向北亞,看來3月冬季系統又有戲了。
目前最重要就是強冷氣團挑戰寒流倒數3天,
冷高壓已經在中亞出現,明天將會移往蒙古發展,
而,
這兩天影響台灣的東北亞冷高壓,因不夠強,
外側的東北季風往太平洋變性為偏東風,
偏東風與內側的東北季風輻合,一度台灣外海輻合出小氣旋地面秀,
當然在惡劣環境下,這種小氣旋很快消散就只是降雨,
今起,東北亞的冷高壓南下,台灣北部溫度稍微降低,
但東北亞冷高壓一南下就更弱,
原先偏東風變成回南風,原先東北風變成偏東風,
於是,
偏東風和偏南風輻合,可能台灣東北外海又有小氣旋秀;
台灣東北近海若出現輻合氣旋,
東北風和偏東風的輻合,氣旋秀偏南,重雨區就是宜蘭,尤其蘇澳或蘇花;
偏東風和偏南風的輻合氣旋秀,氣旋秀偏北,重雨區就會是東北角北海岸了;
因此,
今天貢寮東北角到基隆北海岸雨勢要加大了。
明晚鋒面接近,高空有槽線,小氣旋秀開始變身往溫帶氣旋發展然後東北移出,
重雨區再轉往北北基桃竹苗了。
週六當然就是蒙古冷高壓分裂南下了,異常強極渦事件冷冷冷的重頭戲了。
一般來說,至少冷五天到一週,甚至更久了...在觀察了。
(以上供參囉)
