Antarctic rare extreme weather generated “mother of pearl clouds
People’s Network August 2 News, Reuters reports: Recently, Australian scientists said that in Antarctica, extreme weather conditions present a rare “nacreous clouds” spectacle, which may reflect global warming.
Last week, Australia’s Mawson Station in the Antarctic meteorologists over the thin film to the “mother of pearl clouds.”
winter, the sun just below the horizon, temperatures below minus 80 degrees Celsius (minus 112 degrees Fahrenheit), the order to form a “mother of pearl clouds.” Australian Antarctic research station expert Andrew克莱克希克(Andrew Klekociuk) said, “mother of pearl clouds” formed in the high polar latitudes in winter, because the polar mountain updraft formed.
meteorologist Lainibeike (Renae Baker) said, according to data from weather balloons, surface over the 20 km in the stratosphere the temperature is about minus 87 degrees Celsius (minus 124.6 degrees Fahrenheit). Shooting to the “mother of pearl clouds,” Baker said: “It almost reached the lowest surface temperature.”
This rare “mother of pearl clouds,” also known as “polar stratospheric clouds,” which is not only a curiosity under the one found克莱克希克said: “This cloud shows the extreme climatic conditions, it will damage the ozone layer, chemical changes.”
克莱克希克said that the stratosphere in the ground 8 to 50 1000 meters of altitude, it will rise with the decline in global temperatures over the past 25 years of data collected confirm the situation.
He said: “During this time, the stratospheric temperature is a modest drop in elevation than the surface temperature changes more quickly.”
“mother of pearl cloud” color is due to sunset. Stratospheric winds of 230 kilometers per hour (143 miles per hour), strong winds causes water droplets to form tiny ice crystals, which are increasingly dim reflection of the sunset light, emerged in pearl-like color. (Wei Yuan)
南极罕见的极端天气产生的“云的珍珠母
人民网8月2日消息，路透社报道：近日，澳大利亚科学家说，在南极，极端天气条件下提出一个罕见的“珠母云”奇观，反映的可能是全球变暖。
上周在主持薄膜的珍珠云“母亲的南极气象专家，澳大利亚的莫森站。”
冬天，太阳只是地平线下，气温低于零下80摄氏度（零下112华氏度），订单，形成了珍珠云“妈妈。”澳大利亚南极研究站的专家安德鲁克莱克希克（安德鲁克莱克希克）说：“在冬季高纬度地区形成的极地云层珍珠”妈妈，是因为极地高山上升气流形成的。
气象学家Lainibeike（家丽娜贝克）说，据气象气球，在平流层的温度为20公里的地面资料约零下87摄氏度（零下124.6华氏度）。射击的珍珠云“妈妈，”贝克说：“这几乎达到了最低的表面温度。”
这种罕见的“珠母云”，也称为“极地平流层云”，这不仅是在一个已知的好奇心发现克莱克希克说：“这云表明极端恶劣的气候条件下，将损害臭氧层层，化学变化。“
克莱克希克说，在地面8至50海拔1000米的平流层，它会上升，在过去25年收集的数据证实了局势年全球气温下降。
他说：在此期间，“同温层的温度是一个比地面温度变化海拔小幅下降得更快。”
“珍珠云”颜色是由于日落母亲。 230每小时（143英里每小时）公里的平流层风，强风使水滴形成小冰晶，这是更加黯淡的夕阳光反射，出现了珍珠般的颜色。 （魏元）06.8.3
