Book Description
An atmospheric profiling system has been developed at the University of Tennessee Space Institute. The system consists of temperature, pressure, humidity, relative wind, and a Global Positioning System GPS to track the payload's position. A data logger unit was integrated into the instrument for saving measured atmospheric properties. The atmospheric profiling system was carried through the troposphere and up to the middle region of the stratosphere layer using high altitude balloons. The balloon is assumed to follow a Lagrangian path where the relative horizontal wind represents turbulent perturbations (i.e. gusts). The Parcel theory (a numerical model) used in meteorology to predict atmospheric instability and the Richardson number schemes used for turbulence were adopted in investigating the presence of turbulence indicators. Theories and terminologies relevant for the analysis of turbulence are described and the results from both methods were analyzed and compared.

Book Description
In recent decades, great progress has been made in our understanding of zonal jets across many subjects - atmospheric science, oceanography, planetary science, geophysical fluid dynamics, plasma physics, magnetohydrodynamics, turbulence theory - but communication between researchers from different fields has been weak or non-existent. Even the terminology in different fields may be so disparate that researchers working on similar problems do not understand each other. This comprehensive, multidisciplinary volume will break cross-disciplinary barriers and aid the advancement of the subject. It presents a state-of-the-art summary of all relevant branches of the physics of zonal jets, from the leading experts. The phenomena and concepts are introduced at a level accessible to beginning graduate students and researchers from different fields. The book also includes a very extensive bibliography.

Book Description
COSPAR Space Research, Volume 20 covers the proceedings of the open meetings of the Working Groups on Physical Sciences of the 22nd Plenary Meeting of COSPAR in Bangalore, India on May 29-June 9, 1979. This volume is organized into four parts encompassing 50 chapters that review significant advances in space research concerning the Earth's atmosphere and plasma envelope, as well as in the planetary science and astronomy fields. Part I describes the unique properties of the different layers of the Earth's neutral atmosphere, including the tropical troposphere, stratosphere, and mesosphere. This part also deals with the measurements of atmospheric radiation, the application of remote sensing by satellites to radiation climatology, the structure and circulation of the stratosphere and mesosphere, and the theory and application of thermospheric models. Part II highlights the research studies concerning the chemistry and energetic charged particle effect in the ionosphere. This part also examines the in situ measurements of equatorial ionosphere and the distribution of singly ionized helium through backscatter observations. Part III contains surveys associated with some planetary components, such as the comets, moon, and Venus. This part specifically discusses the data obtained from different probes, models, and analytical techniques to study these components. Part IV explores research works on the sun, cosmic ray, and infrared and gamma-ray astronomy. This book is intended primarily to astronomers and space scientists and researchers.

Book Description
The classic textbook from Pijush Kundu, Fluid Mechanics, has been once again revised and updated by Dr. David Dowling and Dr. Jesse Capecelatro to better illustrate this important subject for modern students. With expanded topics and concepts presented more clearly in a revised didactic sequence, Fluid Mechanics, Seventh Edition guides students from the fundamentals to the analysis and application of fluid mechanics, including turbulence, gravity waves, compressible flow and such diverse applications as aerodynamics and geophysical fluid mechanics. Its broad and deep coverage, provided by 15 Chapters, 4 Appendices, 144 examples, and 568 exercises, continues to be ideal for both a first or second course in fluid mechanics at the graduate or advanced undergraduate level, and is well-suited to the needs of modern scientists, engineers, mathematicians, and others seeking fluid mechanics knowledge. - As with prior editions, the new edition continues to accommodate the needs of upper-level students who have completed minimal prior study of fluid mechanics - Enriched with 10 new real-world examples and 66 new exercises? - Computational worked examples and exercises using MATLAB have been added? - For improved clarity and readability much of the text has been re-written and chapter ordering has been revised

Book Description
The past 15 years have seen marked progress in observing, understanding, and predicting weather. At the same time, the United States has failed to match or surpass progress in operational numerical weather prediction achieved by other nations and failed to realize its prediction potential; as a result, the nation is not mitigating weather impacts to the extent possible. This book represents a sense of the weather community as guided by the discussions of a Board on Atmospheric Sciences and Climate community workshop held in summer 2009. The book puts forth the committee's judgment on the most pressing high level, weather-focused research challenges and research to operations needs, and makes corresponding recommendations. The book addresses issues including observations, global non-hydrostatic coupled modeling, data assimilation, probabilistic forecasting, and quantitative precipitation and hydrologic forecasting. The book also identifies three important, emerging issues-predictions of very high impact weather, urban meteorology, and renewable energy development-not recognized or emphasized in previous studies. Cutting across all of these challenges is a set of socioeconomic issues, whose importance and emphasis-while increasing-has been undervalued and underemphasized in the past and warrants greater recognition and priority today.
