位於美國蒙大拿州(Montana)北部的冰川國家公園(Glacier National Park),縱然踏入夏季仍降下大雪。
雖然美國普遍各區已踏入夏日溫度,但猶他州(Utah)、愛達荷州(Idaho)和蒙大拿州(Montana)的居民,在醒來的時候卻困惑地發現下了雪。
蒙大拿州
在冬季拍下的嗎? 不,是在今年6月17日 在冰河國家公園拍下的。

冬季並未離開洛磯山脈北部,其中一個旋轉上層左低阿爾塔,猶他州週二降下9英寸 厚雪,這是當地六月份第三個最高單日降雪總量。
週三,降雪量如大雨澆透明尼蘇達州(Minnesota)南部的,曼凱托(Mankato)出現水浸,及造成泥石流,迫使一些高速公路關閉。

on June 17 looked more like Christmas time.
Winter just won't quit in
the Northern Rockies where an upper-level low
was swirling early this week. This picture was taken at Lamoille
Canyon in Nevada where 3-4 inches were recorded

雖然出現大量降雪的地區是位於緯度較高的地方,但現已踏入夏季,這景象是尋常的嗎?
現時沒有明顯數據支持是與「極地漩渦」(Polar Vortex)有關,但綜觀今年初美國遭受極地漩渦的侵襲,不難相信北半球的氣候出現了嚴重的變化。
