2010北京大雪紛飛過新年(視頻)

A strong cold wave is sweeping over most of China. Northern cities such as Beijing, Tianjin and others in Hebei Province are embracing the new year's first snowfall.

Beijing saw snow at the beginning of November, but hasn't seen any of the white stuff since. The Beijing Meteorological Bureau says the snow will be followed by strong wind and a possible blizzard.

Residents could experience a significant temperature drop between Tuesday and Thursday, when the mercury could dip to minus 15. The Central Meteorological Station is issuing an orange alert, warning most areas in north, central and east China can expect temperatures to drop 8 to 12 degrees Celsius in a single day.

Under an orange alert, the departments of railway, communication, electricity and transportation must increase the maintenance of roads, railways and power lines. The station is also reminding people to dress warmly during the cold and to reduce outdoor activities.

寒潮暴雪結(jié)冰預(yù)警連發(fā)雪后氣溫創(chuàng)33年新低

從2日開始，北京氣象臺(tái)輪番發(fā)布寒潮、暴雪、道路結(jié)冰三種預(yù)警。2日晚7時(shí)再次發(fā)布寒潮藍(lán)色預(yù)警信號(hào)，稱3日后半夜雪停后北京將有五六天大風(fēng)，氣溫下降 7℃到8℃。2日晚9時(shí)50分，北京氣象臺(tái)發(fā)布今年首個(gè)道路結(jié)冰黃色預(yù)警信號(hào)。對(duì)此氣象專家表示，近日來北京地區(qū)氣溫較低，白天最高氣溫在-6℃到-9℃ 之間，非常寒冷，哪怕1毫米的降雪都很難融化，更別說是強(qiáng)度如此大的降雪。

3日凌晨3時(shí)20分，北京氣象臺(tái)發(fā)布今年首個(gè)暴雪藍(lán)色預(yù)警信號(hào)，上午8時(shí)50分，追發(fā)暴雪黃色預(yù)警信號(hào)，稱未來12小時(shí)內(nèi)降雪仍將持續(xù)，北京大部分地區(qū)降雪量可達(dá)大雪級(jí)別，局部地區(qū)可達(dá)暴雪量級(jí)。暴雪預(yù)警信號(hào)分四級(jí)，分別以藍(lán)色、黃色、橙色和紅色表示。

"在如此密集的時(shí)間里，集中發(fā)布三種氣象預(yù)警信號(hào)，在我的印象中好像是第一次。"北京專業(yè)氣象臺(tái)氣象專家劉工程師說。

據(jù)介紹，這場(chǎng)雪持續(xù)時(shí)間長(zhǎng)，雪量大，各個(gè)氣象站的降水量一直在增長(zhǎng)。3日早晨6時(shí)，居庸關(guān)站的降水量就已顯示為7毫米，達(dá)到大雪級(jí)別；到8時(shí)左右，幾乎所有郊區(qū)站都顯示降水量越過5毫米，達(dá)到大雪級(jí)別。據(jù)介紹，到3日后半夜降雪停止后，全市多個(gè)氣象站點(diǎn)顯示的降水量超過10毫米，因此這場(chǎng)大雪可定義為"今年首場(chǎng)、今冬第四場(chǎng)全市性的大到暴雪。"
