Collaborative Research: Structure and Evolution of the East Pacific Intertropical Convergence Zone under the Influence of Easterly Waves & the Madden-Julian Oscillation in EPIC

EPIC（Eastern Pacific Investigation of Climate Processes in the Coupled Ocean-Atmospheric System）是美国气候变化研究计划（CLIVAR Program）的一项活动。EPIC 2001由四个部分组成，重点是（i）热带辐合区/暖池现象;（ii）进入热带辐合区的越赤道气流;（iii）海洋上层结构和混合;以及（iv）东南信风区边界层云特性的探索性研究。EPIC 2001的实地调查阶段定于2001年9月1日至10月15日期间进行，为期6周。除了ATM的八个奖项外，这项合作研究还获得了NSF/OCE和NOAA/OGP的奖项。在这个奖项下（与Zehnder/Arizona State Univ ATM 0104234合作），PI将在每周的时间尺度上研究东太平洋ITCZ强度和位置波动的因素。ITCZ对流的变化作为一个功能的昼夜循环也将被检查。这项工作很重要，因为它将改善对热带太平洋东部气候变化的理解和建模。

EPIC (Eastern Pacific Investigation of Climate processes in the coupled ocean-atmosphere system) is an activity of the US CLIVAR Program. EPIC 2001 consists of four components focussing on (i) intertropical convergence zone/warm pool phenomena; (ii) cross-equatorial inflow into the intertropical convergence zone; (iii) upper ocean structure and mixing and (iv) an exploratory study of boundary layer cloud properties in the southeasterly tradewind regime. The field phase of EPIC 2001 is scheduled for a 6-week period during the interval Sept 1 to Oct 15, 2001. In addition to the eight awards made by ATM, this collaborative research has awards made by NSF/OCE and NOAA/OGP.Under this award (collaborative with Zehnder/Arizona State Univ ATM 0104234), the PI will examine factors responsible for the fluctuations in the strength and position of the East Pacific ITCZ on weekly time scales. The variations of the ITCZ convection as a function of the diurnal cycle will also be examined. The work is important because it will improve understanding and modeling of climate variability over the Eastern Tropical Pacific.
