RIME Implementation Workshop

该奖项将提供资金支持一个关于南极区域尺度天气气象过程及其在数值预报模式中的表现的讲习班。其目标是评估我们目前对南方高纬度地区的物理过程的了解，并提供一种方法来制定具体的实验，以产生新的信息，以便可以测试和改进数值模式中的必要参数化。研讨会将于2003年2月4日至6日在美国国家大气研究中心举行。几乎每一项涉及全球变化问题的研究都将极地地区列为对气候变化最敏感的地区之一。南极大陆由于其巨大的冰盖和对海平面变化的潜在影响，在全球变化情景中具有特别重要的意义。此外，近年来，从天气周期到与厄尔尼诺-南方涛动（ENSO）相关的时间尺度上，南极洲与低纬度地区之间存在着许多远距联系。然而，对南极过程如何与全球其他地区的过程联系在一起的物理理解仍然缺乏在所有时间尺度上。调查和了解南极洲与全球其他地区之间的联系的先决条件是彻底了解区域物理和天气过程以及进出该大陆的运输。南极过程的适当表述是全球变化研究的基础，特别是因为南极运输与当地地形和中尺度过程密切相关，而这些过程目前尚未在全球气候模式（GCMs）中得到解决。罗斯岛气象实验是一个基础和应用研究项目，旨在突出和弥补我们目前在南极天气过程知识方面的差距。

This award will provide funds for the support of a workshop on Antarctic regional-scale synoptic meteorological processes and their representation in numerical forecast models. Its objectives are to assess our current understanding of physical processes at high southern latitudes and to provide a means for formulating specific experiments to generate new information so that necessary parameterizations within numerical models can be tested and improved. The workshop will be held at the National Center for Atmospheric Research on February 4-6, 2003. Nearly every study that addresses issues of global change identifies the polar regions as among those most sensitive to climatic shifts. The Antarctic continent is a particular importance in global change scenarios because of its massive ice sheets and potential impacts on sea level change. In addition, numerous teleconnections between Antarctica and lower latitudes over time scales ranging from synoptic periods to those associated with the El Nino-Southern Oscillation (ENSO) and beyond have been documented in recent years. However a physical understanding of how Antarctic processes are linked to those over the rest of the globe is still lacking on all time scales. A prerequisite for investigating and understanding the links between Antarctica and the rest of the globe is a thorough understanding of regional physical and synoptic processes and transports to and from the continent. Proper representation of Antarctic processes is basic to global change studies, especially since Antarctic transports are strongly tied to local topographic and mesoscale processes that are currently not resolved within global climate models (GCMs). These considerations have been brought together in the Ross Island Meteorological Experiment, a basic and applied research program, designed both to highlight and remedy current gaps in our knowledge of Antarctic synoptic processes.
