<p>來自移動極地渦旋的三輪寒冷北極空氣中的第一輪已使美國中部和東部的氣温驟降，威脅到從愛荷華州到緬因州的數百年低温記錄。</p>
<p>氣象學家預測，在接下來的兩週內，數百萬人將面臨兩次更強的寒冷氣温襲擊。</p>
<p>AccuWeather 高級氣象學家 Renee Duff 表示：“本週將以本季迄今為止最冷的空氣結束，隨着一股冷鋒從中西部向東北部和中大西洋地區推進。”</p>
<p>Duff 解釋道：“極地渦旋的位移使北極空氣滲入美國中部和東部。下週有第二輪寒潮的預報，而本月中旬可能會有第三輪寒冷空氣。”</p>
<h2><strong>北極空氣何時到達？會有多冷？</strong></h2>
<p>週四，嚴寒的氣温襲擊了中西部的部分地區。在愛荷華州，十多個城市創下了新的低温記錄。在沃特盧，氣温為-15 度，打破了 1991 年創下的-7 度記錄。</p>
<p>未來幾天可能會有更多記錄被打破。</p>

<p>在接下來的幾天裏，中西部、俄亥俄河谷和中大西洋地區可能會出現創紀錄的寒冷天氣。預計明天早晨中西部部分地區的低温將降至零度以下。請確保適當着裝，以避免凍傷/低體温的風險，並限制户外活動時間。 pic.twitter.com/QZJ9Th2JIY</p>

<p>週五早晨，北中大西洋和新英格蘭地區感受到了寒冷。</p>
<p>在紐約市，氣温徘徊在 20 度左右，而新英格蘭大部分地區的氣温在低十到中十度之間。在紐約州的奧爾巴尼，氣温為個位數：零度以上 1 度。</p>

<p>由於北極空氣的襲擊，從達科他州和明尼蘇達州到愛荷華州和內布拉斯加州也預計會出現零下氣温。</p>
<p>在接下來的幾天裏，以下是 NWS 的總體氣温預報：</p>
<ul>
<li>中西部：十幾度到 20 度</li>
<li>新英格蘭：20 度到 30 度</li>
<li>中部/南部平原東至中大西洋：30 度到 40 度</li>
<li>德克薩斯州和東南部：40 度到 50 度</li>
</ul>
<p>AccuWeather 首席長期氣象學家 Paul Pastelok 表示：“本週的寒潮將是可能的三輪寒潮中的第一輪。下週可能會有另一輪寒潮，之後一週還會有第三輪。”</p>
<h2><strong>什麼是極地渦旋？</strong></h2>
<p>讓我們從 “極地” 部分開始。一個大範圍的低氣壓和冷空氣始終環繞着地球的南北極。“渦旋” 指的是保持冷空氣靠近兩極的逆時針氣流方向。根據 NWS 的説法，在北半球的冬季，極地渦旋擴展是很常見的，它將來自北極的冷空氣沿着噴流推向南方。</p>
<h2><strong>如果停電，如何保持安全</strong></h2>
<p>AccuWeather 建議人們完成冬季化家庭和水管的工作，並儘快檢查爐子，訂購取暖油或丙烷。</p>
<p>以下是美國紅十字會在停電和主要供熱源失效時推薦的一些事項：</p>
<ul>
<li>僅在户外且遠離窗户的地方使用發電機、燒烤架和露營爐，以防止一氧化碳中毒。</li>
<li>切勿使用烹飪烤箱或爐灶來加熱家中，因為這可能導致一氧化碳中毒和家庭火災。</li>
<li>由於火災風險，使用電池供電的燈籠或手電筒，而不是蠟燭。</li>
<li>關閉不需要的房間。</li>
<li>使用壁爐和取暖器時要小心。確保任何可能着火的物品與熱源保持至少 3 英尺的距離。</li>
</ul>
<h2><strong>如果必須外出，如何保持安全</strong></h2>
<p>美國紅十字會建議，如果您必須外出，儘量覆蓋儘可能多的皮膚以避免凍傷。穿着寬鬆的多層保暖衣物和帽子；手腕緊的手套比普通手套更好。佩戴滑雪面罩或圍巾以幫助遮住面部，並儘可能穿防水靴，以保持雙腳乾燥。</p>
<p>避免因在深雪中行走而導致的過度勞累；這可能引發心臟病發作或更嚴重的醫療狀況。</p>

COLD

<p>三重極地渦旋正在導致美國中部和東部的氣温驟降，威脅創下歷史低温。氣象學家預測未來幾周還將出現兩次北極冷空氣侵襲。建議採取安全措施以應對停電和户外活動，以防止凍傷和低體温症</p>

<p>The first of three rounds of cold Arctic air from a shifting polar vortex has sent temperatures plunging across the central and eastern U.S., threatening centuries-old record lows in cities and towns from Iowa to Maine.</p>

</div><h2><strong>What is a polar vortex?</strong></h2>
<div class="lb-trans"><h2><strong>什麼是極地渦旋？</strong></h2>
</div><p>Let’s start with the “polar” part. A large area of low pressure and cold air is always surrounding Earth’s north and south poles. “Vortex” refers to the counterclockwise direction of air that keeps the colder air near both poles. During wintertime in the northern hemisphere, it’s common for the polar vortex to expand, pushing the cold air from the north pole to the south along the jet stream, according to the NWS.</p>
