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).

带电水滴和冰粒在许多自然现象中起着重要作用。 最明显的例子是伴随雷暴、龙卷风和活火山的闪电。 这种带电的关键是在水或冰表面破裂时发生的电荷分离。 最近化学家和物理学家在水和冰界面上的实验和理论进展正在打开在分子水平上理解带电的可能性。 这些进展激发了将于2009年8月10日至14日在科罗拉多特柳赖德举行的研讨会。 来自工程、化学、物理学和物理气象学等不同领域的科学家将齐聚一堂，深入了解自然环境中的电气化现象。一位与会者将向数百名游客和特柳赖德居民发表公开演讲。 这是碲化物科学研究中心的一个常规功能，该中心将主办研讨会。 这种教育推广活动可能会激励其他参与者在自己的社区举办类似的受欢迎的讲座。 闪电对建筑物和它所击中的任何东西都有相当明显的影响。 对水和冰带电的更好理解也可能有助于深入了解人类活动的影响（例如，大气中二氧化碳和其他污染物的增加）。
