中文摘要:

黑碳(BC ) 是最有效的不可溶解的轻吸收的微粒(ILAP ) ,它能强烈在可见波长吸收太阳的放射。一旦 BC 经由干燥或湿的过程在雪中被扔,甚至 BC 的小数量能显著地减少雪反照率,提高太阳的放射的吸收,加速雪融化,和原因气候反馈。BC 靠着公司被认为第二个很重要的部件 < 潜水艇 class= “ a-plus-plus ” > 2 以全球温暖。同样,矿物质灰尘(MD ) 是 ILAP 的另一种类型。到目前为止,很少注意都没在东亚的 midlatitudes 在雪表面上对 BC 和 MD 免职的量的大小被给予,特别在北中国上。在这份报纸,我们集中于考察为在山范围上在高亚洲的冰河收集并且测量清除 BC 和 MD 执行的几个实验(例如喜马拉雅山脉) 并且在在北中国上的季节的雪中。从调查文学的结果显示在季节的雪中的 ILAP 的吸收被 MD 在内部蒙古的区域结束在 Qilian 山并且由本地土壤灰尘统治清扫来源。当雪样品与 MD 被混合时,在用现代技术的雪和冰核心中的 BC 的察觉有大偏爱和 uncertty。证据也显示由 BC 和 MD 不安的雪反照率的减小能显著地增加网表面太阳的放射,升起,减少雪累积,并且加速雪融化的原因表面空气温度。

英文摘要:

Black carbon (BC) is the most eff ective insoluble light-absorbing particulate (ILAP), which can strongly absorb solar radiation at visible wavelengths. Once BC is deposited in snow via dry or wet process, even a small amount of BC could signifi cantly decrease snow albedo, enhance absorption of solar radiation, accelerate snow melting, and cause climate feedback. BC is considered the second most important component next to CO2 in terms of global warming. Similarly, mineral dust (MD) is another type of ILAP. So far, little attention has been paid to quantitative measurements of BC and MD deposition on snow surface in the midlatitudes of East Asia, especially over northern China. In this paper, we focus on reviewing several experiments performed for collecting and measuring scavenging BC and MD in the high Asian glaciers over the mountain range (such as the Himalayas) and in seasonal snow over northern China. Results from the surveyed literature indicate that the absorption of ILAP in seasonal snow is dominated by MD in the Qilian Mountains and by local soil dust in the Inner Mongolian region close to dust sources. The detection of BC in snow and ice cores using modern techniques has a large bias and uncertainty when the snow sample is mixed with MD. Evidence also indicates that the reduction of snow albedo by BC and MD perturbations can signifi cantly increase the net surface solar radiation, cause surface air temperature to rise, reduce snow accumulation, and accelerate snow melting.
