This workshop will review recent advances on the dynamics of storm tracks, jets and their modes of variability and to address key questions related to the regional response to climate change. The conference will focus on areas of research in which recent progress has been notable, along with emerging themes: characterization of storm track response to climate change, model hierarchies of the storm tracks, model biases, low-frequency variability, coupling to the cryosphere, ocean, stratosphere and tropics, coupling with moisture and clouds and connection to extreme events.Storm tracks and jets, together with their modes of variability, affect the regional distribution of precipitation, temperature, and wind in the midlatitudes of both hemispheres. One of the most pressing questions regarding the impacts of climate change concerns how storm tracks will change. While comprehensive climate models predict a poleward shift of the zonal-mean midlatitude westerlies in response to global warming, observational evidence is mixed, and such a shift does not necessarily occur regionally, particularly in the Northern Hemisphere. The importance of understanding the dynamics and robustness of the regional response cannot be understated. It requires a better understanding of the conditions setting the time-mean structure of the storm tracks and jets, their low-frequency variability, and the role of boundary conditions (cryosphere, ocean, stratosphere, and tropics). The resulting changes to climate and weather (e.g., likelihood of extreme events) are also affected by coupling with moisture and clouds.The workshop will be held in Grindelwald, Switzerland 24-28 August 2015. NSF funds will support travel costs for approximately 6 early career scientists from the U.S.

该研讨会将回顾有关风暴轨迹，喷气机及其可变性方式的动态的最新进展，并解决与气候变化区域反应有关的关键问题。会议将重点关注的是最新进展以及新兴主题的研究领域：风暴跟踪对气候变化的反应的特征，模型的模型层次结构，模型偏见，低频可变性，与Cryosphere，海洋，海洋，海洋，平流层和热带和云层的变化以及稳定性的范围以及jets的变化，以及jets的变化。两个半球的中纬度的降水，温度和风的。关于气候变化影响的最紧迫的问题之一是风暴轨迹将如何变化。虽然综合气候模型预测Zonal均值中纬度西风的极端转移会响应全球变暖，但观察性证据是混合的，这种转变不一定在区域发生，尤其是在北半球。理解区域反应的动态和鲁棒性的重要性不能被低估。它需要更好地理解设定风暴轨迹和喷气机的时间均值结构，其低频变异性以及边界条件（冰晶，海洋，平流层和热带）的作用。气候和天气的变化（例如，极端事件的可能性）也受到与水分和云的耦合的影响。该研讨会将于2015年8月24日至28日在瑞士格林德瓦尔德举行。NSF资金将支持美国大约6个早期职业科学家的旅行费用
