中文摘要：

在这研究，作者使用天气研究和预报模型( WRF-Chem )的化学版本检验导致的碳( BC )在在 0800 1月26日期间发生在南部的中国到 0800 1月29日的严重暴风雪期间在模仿的温度和 降水上在雪反照率改变的黑色的影响 2008 (除了当不那样说了时，所有时间是本地时间的笔记)。黑碳喷雾器在 WRF-Chem 以内在网上被模仿。模型结果显示出那表面反照率，平均超过 2728 1 月，能被 BC 的免职被多达 10% 减少。作为结果，相对模拟，那不在雪/冰上考虑 BC 的免职，预言的表面空气温度能由 -1.95 在 2728 1月期间不同到 2.70 K ，并且在 2728 1月的预言的积累的 降水能与大 BC 免职在区域 A 和 B 上由 -2.91 不同到 3.10 公里。变化的不同符号被云的反馈并且由水蒸汽的可获得性在空气决定。

英文摘要：

In this study the authors apply the chemistry version of the Weather Research and Forecasting model （WRF-Chem） to examine the impacts of black carbon （BC）-induced changes in snow albedo on simulated temperature and precipitation during the severe snowstorm that occurred in southern China during 0800 26 January to 0800 29 January 2008 （Note that all times are local time except when otherwise stated）. Black carbon aerosol was simulated online within the WRF-Chem. The model resuits showed that surface-albedo, averaged over 27-28 January, can be reduced by up to 10% by the deposition of BC. As a result, relative to a simulation that does not consider deposition of BC on snow/ice, the authors predicted surface air temperatures during 27-28 January can differ by -1.95 to 2.70 K, and the authors predicted accumulated precipitation over 27-28 January can differ by -2.91 to 3.10 mm over Areas A and B with large BC deposition. Different signs of changes are determined by the feedback of clouds and by the availability of water vapor in the atmosphere.
