热带气旋结构(TCS08)在2008年8月和9月期间与THORPEX太平洋亚洲区域运动(T-PARC)合作，是自1990年以来西北太平洋与热带气旋有关的最重要的实地试验。本文将总结TCS08的科学基础、观测平台和战略。TCS08的热带气旋形成部分将涉及多尺度方面，但主要重点将是天气尺度上的通风假说和有袋类范例，以及中尺度上的自上而下和自下而上的假说。许多数值模拟、伴随敏感性和目标性研究以及观测研究支持TCS08地层成分。TCS08结构变化分量的主要焦点是与次生眼壁形成有关的变化，通过边界层卷动和海洋响应和反馈产生的海气相互作用影响，以及对超强的理解。TCS08结构变化部分的一个主要目标是对强度和结构及其变化进行现场观测，以验证星基技术。数值模拟和数据同化研究也将支持结构变化部分。西北太平洋的远程闪电网络正在扩大，至少有五个新的观测站，这些观测将与强度变化联系起来，并结合模拟研究。开放的数据政策适用于TCS08和T-PARC，并鼓励研究人员在现场实验以及TCS08数据集的分析、数值模拟和解释方面进行合作。
The Tropical Cyclone Structure (TCS08) in cooperation with the THORPEX Pacific Asian Regional Campaign (T-PARC) during August and September 2008 is the most significant tropical cyclone-related field experiment in the western North Pacific since 1990. This article will summarize the science basis, observational platforms, and strategy for the TCS08. The tropical cyclone formation component of TCS08 will address the multi-scale aspects, but the primary focus will be on a ventilation hypothesis and a marsupial paradigm on the synoptic scale, and a top-down and a bottom-up hypothesis on the mesoscale. A number of numerical modeling, adjoint sensitivity and targeting, and observational studies are supporting the TCS08 formation component. The primary foci of the structure change component of TCS08 are changes associated with secondary eyewall formation, air-sea interaction impacts via boundary layer rolls and the ocean response and feedback, and understanding of superintensity. A major objective of the TCS08 structure change component is to make in situ observations of the intensity and structure and their changes for validating satellite-based techniques. Numerical modeling and data assimilation studies will also support the structure change component. The long-range lightning network in the western North Pacific is being augmented with at least five new stations and these observations will be correlated with intensity changes in conjunction with modeling studies. An open data policy applies to both TCS08 and T-PARC, and researchers are encouraged to collaborate in the field experiments and in the analyses, numerical modeling, and interpretations of the TCS08 data sets.
