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.

东太平洋海气耦合系统气候过程调查(EPIC)是美国CLIVAR计划的一项活动。EPIC 2001由四个部分组成，重点是(I)热带辐合带/暖池现象；(Ii)热带辐合带的越赤道流入；(Iii)上层海洋结构和混合；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，这项合作研究还有美国国家科学基金会/海洋和大气层管理局/OGP颁发的奖项。在这个奖项下(与泽德/亚利桑那州立大学ATM 0104234合作)，PI将研究导致东太平洋ITCZ力量和位置每周时间尺度波动的因素。还将研究ITCZ对流作为日循环的函数的变化。这项工作很重要，因为它将改善对东热带太平洋气候变异性的理解和建模。
