Book Description
The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics", I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.

Book Description
This book presents a unique and comprehensive view of the fundamental dynamical and thermodynamic principles underlying the large circulations of the coupled ocean-atmosphere system Dynamics of The Tropical Atmosphere and Oceans provides a detailed description of macroscale tropical circulation systems such as the monsoon, the Hadley and Walker Circulations, El Niño, and the tropical ocean warm pool. These macroscale circulations interact with a myriad of higher frequency systems, ranging from convective cloud systems to migrating equatorial waves that attend the low-frequency background flow. Towards understanding and predicting these circulation systems. A comprehensive overview of the dynamics and thermodynamics of large-scale tropical atmosphere and oceans is presented using both a “reductionist” and “holistic” perspectives of the coupled tropical system. The reductionist perspective provides a detailed description of the individual elements of the ocean and atmospheric circulations. The physical nature of each component of the tropical circulation such as the Hadley and Walker circulations, the monsoon, the incursion of extratropical phenomena into the tropics, precipitation distributions, equatorial waves and disturbances described in detail. The holistic perspective provides a physical description of how the collection of the individual components produces the observed tropical weather and climate. How the collective tropical processes determine the tropical circulation and their role in global weather and climate is provided in a series of overlapping theoretical and modelling constructs. The structure of the book follows a graduated framework. Following a detailed description of tropical phenomenology, the reader is introduced to dynamical and thermodynamical constraints that guide the planetary climate and establish a critical role for the tropics. Equatorial wave theory is developed for simple and complex background flows, including the critical role played by moist processes. The manner in which the tropics and the extratropics interact is then described, followed by a discussion of the physics behind the subtropical and near-equatorial precipitation including arid regions. The El Niño phenomena and the monsoon circulations are discussed, including their covariance and predictability. Finally, the changing structure of the tropics is discussed in terms of the extent of the tropical ocean warm pool and its relationship to the intensity of global convection and climate change. Dynamics of the Tropical Atmosphere and Oceans is aimed at advanced undergraduate and early career graduate students. It also serves as an excellent general reference book for scientists interested in tropical circulations and their relationship with the broader climate system.

Book Description
This textbook introduces fundamental dynamics of tropical atmosphere and ocean useful for advanced graduate courses in atmospheric and climate sciences. It presents an overview of simple atmospheric and oceanic models, as well as the observed phenomena associated with major climate modes in the tropics. It provides students with an up-to-date understanding of the dynamics of tropical climate and weather phenomena. A particular focus is given to scale interactions and atmosphere-ocean interactions associated with tropical mean climate (such as ITCZ asymmetry and annual cycles), synoptic-scale variability (such as synoptic wave trains, easterly waves and tropical cyclones), intraseasonal oscillations (such as Madden-Julian Oscillation and boreal summer intraseasonal oscillation), and interannual variability (such as El Niño-Southern Oscillation and Indian Ocean Dipole). Theoretical and conceptual models are presented for better understanding of physical mechanisms behind the observational phenomena. This book aims to motivate graduate students in atmospheric sciences and oceanography by providing them with the key methods and tools necessary to conduct research.

Book Description
This book discusses the sources of uncertainty in future model projections of the tropical Pacific SST warming pattern under global warming. It mainly focuses on cloud radiation feedback and ocean dynamical effect, which reveal to be the two greatest sources of uncertainty in the tropical Pacific SST warming pattern. Moreover, the book presents a correction for model projections of the tropical Pacific SST warming pattern based on the concept of “observational constraints”; the corrected projection exhibits a more El Niño-like warming pattern.

Book Description
Air-sea interactions are a critical component of the global climate system. Despite this, uncertainty remains in our understanding of air-sea interaction across spatial scales, particularly on small scales, which are not observable by remote sensing and often not explicitly represented in models due to computational limitations. This dissertation provides insight into the key processes that drive air-sea interaction in two tropical regions that are important for modulating synoptic to global-scale weather and climate: the inter-tropical convergence zone and the trade winds. The first chapter uses a series of model experiments based on observations from the rainy eastern tropical Pacific to evaluate the influence of preexisting ocean stratification and tropical rain modes on the upper ocean salinity response to rainfall, a process that modulates how freshwater is incorporated into the ocean structure. Differences in the timing of convective and stratiform components of rain events can modify the duration which surface salinity anomalies persist following rain for over two hours, while strong preexisting stratification can allow near-surface salinity anomalies produced by rain to persist for over seven hours longer compared to when rain falls on a well-mixed ocean. Similar differences in salinity structure can exist at deeper depths of up to 20 meters in the mixed layer. This work provides insight into the limitations of using low-resolution satellite rain observations in the context of physical oceanographic studies and examines a critical component of the global water cycle. The second and third chapters use observations from surface drifters and autonomous vehicles that measure the atmosphere and near-surface ocean in the tropical Atlantic trade wind region to evaluate the spatial variability of ocean surface waves and bulk air-sea fluxes. While previous research has mostly been limited to areas having particularly strong submesoscale activity, this work provides insight into the spatial variability present in a less energetic region representative of larger areas of the global ocean. Surface current variability in the trade winds influence wave slope and air-sea momentum flux due to changes in the relative wind speed and wave-current interactions. Wave-current interactions specifically modify momentum flux by as much as 10%. Across scales of tens of kilometers, air-sea sensible heat, latent heat, and upward buoyancy fluxes vary by 10, 50, and 10 watts per square meter. Sensible heat and upward buoyancy fluxes are significantly influenced by spatial sea surface temperature variability, while latent heat flux variability is primarily driven by changes in the atmosphere. The findings from this work could ultimately be used to guide the development of fully coupled atmosphere-wave-ocean models or quantify the limitations of using lower-resolution remote observations or models. Collectively, the following work serves to elucidate the physics of the dominant small-scale air-sea processes in two regions of the tropical ocean, quantify the influence of these processes on air-sea interaction and upper-ocean mixing, and suggest hypotheses on the implications of neglecting small-scale processes in regional or global studies of the coupled air-sea system.

Book Description
This book focuses on two major challenges in the climate sciences: 1) to describe the decadal-to-centennial variations in instrumental and proxy records; and 2) to distinguish between anthropogenic variations and natural variability. The National Taiwan University invited some of the world's leading experts across the areas of observational analysis, mathematical theory, and modeling to discuss these two issues. The outcome of the meeting is the 23 chapters in this book that review the state of the art in theoretical, observational and modeling research on internal, unforced and externally forced climate variability. The main conclusion of this research is that internal climate variability on decadal and longer time scales is so large that sidestepping it may lead to false estimates of the climate's sensitivity to anthropogenic forcing.World Scientific Series on Asia-Pacific Weather and Climate is indexed in SCOPUS.

Book Description
Changes in sea level caused by global warming can be disastrous to modern civilization. Therefore, it is important to use accurate and reliable methods to monitor any change. During this century, and, in particular, the last three decades, tide-gauge records have been used to show these changes related to the world's oceans. Aubrey and Emery suggest, however, that tidal gauges should not be used unquestioningly as a benchmark for measuring eustatic sea-level changes. Tectonism, subsidence, ocean current variability, and human activity can, and do, affect the accuracy of these records. Understanding the reasons for changes in land and sea levels is essential for the proper development of coastal regions. The results of this study provide guiding data for scientific, engineering, and policy solutions to coastal flooding. Determining the true causes of relative subsidence, and how to use geological and oceanological controls, will allow us to exist within our natural environment, rather than force nature to conform to our legal and temporary 'remedies.'
