Anyone who lives to the lee of the Great Lakes is familiar with a mesoscale meteorological phenomenon know as "lake effect snow storms". Lake effect snows are relatively local weather events that can cause some areas to receive as much as 100 cm of snow while other locations only a few tens of kilometers away may experience barely a trace. In particular, Lake Ontario, because of its length and orientation with respect to the prevailing winds, has an unusually well defined snowbelt with annual snowfall accumulations that exceed 500 cm. Lake effect snows have been recognized and studied for some time with much progress having been made in determining causative factors. Gaps, however, still exist in our knowledge as is evidenced by an inability to consistently predict the timing, location and amount of heavy snows. During the winter of 1990, a private power company, the National Oceanic and Atmospheric Administration and the Pennsylvania State University will collaborate in a joint field effort called the Lake Ontario Winter Storms Project (LOWS). The project will focus on improved understanding and prediction of intense local snowfalls to the lee of Lake Ontario. The field component will bring to bear on this problem advanced mesoscale measuring systems such as Doppler radar, wind and thermodynamic profiling systems, and a microwave radiometer. Under the National Science Foundation's program for Research in Undergraduate Institutions (RUI), the Principal Investigators (PIs) proposes to participate in the LOWS Project. The PIs bring to the project not only their meteorological expertise, but also they will contribute directly to the observational effort by fielding two mobile atmospheric sounding systems which will be operated by undergraduate students from RUI colleges in the area. Post field experiment research will concentrate on diagnostic studies and numerical simulations with the ultimate goal of gaining a better understanding of the environmental structure and physical mechanisms involved in the formation and maintenance of lake effect snows. The activities of the PIs complement nicely the other scientists involved in the project. //

任何住在五大湖背风处的人都熟悉 一种被称为“湖泊效应”的中尺度气象现象 暴风雪”。 湖效应雪是相对局部的天气 这些事件可能导致某些地区接收多达100厘米的 雪，而其他地方只有几十公里远， 体验不到一丝痕迹。 尤其是安大略湖，因为 它的长度和方向相对于现有的 风，有一个异常明确的雪带， 降雪量超过500厘米。 湖效应降雪 已经被认识和研究了一段时间，并取得了很大进展 在确定致病因素时所做的。 差距， 然而，我们所知仍然存在， 无法持续地预测时间、地点和 大量的大雪。 1990年冬天，一家私营电力公司， 国家海洋和大气管理局和 宾夕法尼亚州立大学将在一个联合领域进行合作 这项工作被称为安大略湖冬季风暴项目（LOWS）。 的 该项目将侧重于提高对气候变化的理解和预测， 安大略湖的背风处出现了强降雪。 领域 一个组件将对这个问题产生影响先进的中尺度 测量系统，如多普勒雷达，风和热力学 剖面分析系统和微波辐射计 根据国家科学基金会的研究计划， 在本科院校（RUI），主要研究人员 (PIs)我想参加LOWS项目。 私家侦探带来了 不仅是他们的气象专业知识， 它们将直接为观测工作做出贡献， 部署两个移动的大气探测系统， 由该地区RUI学院的本科生经营。 田间试验后的研究将集中于诊断 研究和数值模拟，最终目标是 更好地了解环境结构， 参与形成和维持的物理机制 湖效应降雪。 PI的活动很好地补充 参与该项目的其他科学家。 //
