Workshop on Electrification of Water Drops and Ice Particles: Simulations in the Laboratory and in the Natural Environment; Telluride, CO; August 10-14, 2009

带电的水滴和冰粒在许多自然现象中起着重要作用。最明显的例子就是伴随雷暴、龙卷风和活火山而来的闪电。这种电气化的关键是在水或冰表面破裂时发生的电荷分离。化学家和物理学家最近在水和冰界面上的实验和理论进展，为在分子水平上理解电气化提供了可能性。这些进步激发了2009年8月10日至14日在科罗拉多州特柳赖德举行的研讨会。来自工程、化学、物理和物理气象学等不同领域的科学家将齐聚一堂，对自然环境中的电气化现象进行更深入的了解。一位与会者将向几百名游客和特柳赖德的居民发表公开演讲。这是特柳赖德科学研究中心（Telluride Science Research Center）的常规活动，该中心将主办此次研讨会。这种教育推广可能会激励其他参与者在他们自己的社区提供类似的受欢迎的讲座。闪电对建筑物和它击中的任何东西都有相当明显的影响。对水和冰的电气化有了更好的了解，也可能导致对人类活动的影响（例如，大气中二氧化碳和其他污染物的增加）有更深入的了解。

Electrified water drops and ice particles play an important role in many natural phenomena. The most obvious example is the lightning that accompanies thunderstorms, tornadoes and active volcanoes. The key to this electrification is the charge separations that occur upon the breakup of water or ice surfaces. Recent experimental and theoretical advances by chemists and physicists at water and ice interfaces are opening up the possibility of understanding electrification on a molecular level. These advances have inspired a workshop to be held in Telluride, Colorado during August 10-14, 2009. Scientists from the diverse communities of engineering, chemistry, physics and physical meteorology will convene to develop a deeper understanding of the phenomena of electrification in the natural environment.One conference participant will present a public lecture to a few hundred visitors and residents of Telluride. This is a regular feature of the Telluride Science Research Center, which will host the workshop. This educational outreach may inspire other participants to offer similar popular lectures in their own communities. Lightning has fairly obvious impacts on structures and anything else that it strikes. An improved understanding of water and ice electrification may also lead to insights into the influences of human activity (e.g., increases in atmospheric carbon dioxide and other pollutants).
